Welcome to our class blog. We are group 4th grade students (ages 9-10) in Mrs. McKelvey’s class in San Diego, California. We are here to share our experiences and work, and learn more about our world. We might even have a few videos in our blog.
Do you want to learn facts about Pandas and maybe even how to save them from extinction? If you read my article, I will tell you all about what they eat, where they live and even tell you the reasons why they are going extinct! This is all in my article so go ahead and read it I would love it if you did.
Pandas live in high in dense bamboo forests in the misty rainy mountains in Southwestern China. Pandas also sometimes live in the Chinese Zoos with a big area to roam around in and with people that adore Pandas so much. Pandas are originally from China. Pandas like to live in cool weather not hot or dry weather just cool climates.
Pandas eat bamboo as you all know, but they also enjoy honey, eggs, fish, fruit, and veggies like oranges, yams, and bananas. They also eat leaves, stems, and shoots. The Giant Pandas eat up to 20-40 pounds of food a day then they poo 50 times a day because they eat so much food.
When baby Pandas are born they weigh three to five ounces like a stick of butter. They are pink in color, blind, hairless, cute, and harmless. Pandas are the smallest newborn mammals relative to their mother’s size. They stay with their mother until they are 2 years old then they can fend for themselves out in the forest.
The reason Pandas are going extinct is that people are destroying the Panda’s habitat for development in China. There are only about 20 patches of forest in China left where the pandas can live. Pandas don’t have enough food to live in the forests. There are now only 1,114 Giant Pandas left alive in the world! Isn’t that horrible.
Pandas are going extinct. Isn’t that sad? So many people adore pandas. The world would be sad without pandas so we should come up with more ideas to help save the panda population.Like, give your loose change to Panda zoos because they also want to help save pandas.
You are the panda bear munching on delicious bamboo straws. WOW! Look out your little baby panda bear almost got tackled by a snow leopard! This article is about panda extinction and a few other facts, do you think pandas are going to go extinct? You should definitely read this article because if you love pandas and just want to know every single bit about them then, read this article!
Giant pandas are becoming extinct because of extensive habitat loss and destruction by hunters. Habitat loss destroys bamboo, which is the giant panda’s natural food source.
Pandas have to eat a lot of bamboo. This is because they do not digest bamboo very well. Pandas can digest only about 17 percent of what they consume. Pandas have to eat a lot of it so they can get nutrients from it. The study notes that the bears evolved from omnivorous ancestors but likely began to specialize in bamboo-chomping 7 million years ago. But in that time, they haven’t evolved to become efficient at breaking down cellulose. As a result, the panda’s stomach and intestinal system are more similar to a carnivore than a vegetarian.
Pandas became endangered on January 23 1984. Throughout many years, the lives of these Giant Pandas have been severely impacted by mainly habitat loss.
A pretty long time ago pandas lived in a large portion of China. Now they only live in a very tiny fraction of what used to be a big area. They live very close to Chang River and Huang River.
Usually, the characteristics of a panda are:
They Have “Cat-Like” Pupils For Seeing Well at Night.
Distinctively Black and White. Giant pandas have a distinctive appearance.
Their Paws Have Six “Fingers”!
To prevent pandas from going extinct people are donating money to panda societies. There are also panda clubs, and the new San Diego zoo is raising some pandas too! If you kill a panda you will be fined. New reproductive technologies that will help preserve sperm and egg DNA for future breeding.
The giant panda is a conservation reliant vulnerable species. A 2007 report showed 239 pandas living in captivity inside China and another 27 outside the country. In December 2014, 49 giant pandas lived in captivity outside China, living in 18 zoos in 13 different countries.
Some of the famous pandas that everyone knows about are:
Tuan Tuan and Yuan Yuan
And a very special brown panda named Su Lin
Su Lin is a one of a kind brown panda, brown pandas are actually very rare like Su Lin. Here I’ll show you a picture
This is Su Lin
You know what a lot of pandas are born in the world i think it’s time to see how many pandas are born each year.
In 2017 a record 42 giant pandas were born at to breeding stations of the China Conservation and Research Center for the Giant Panda On September 6, 2006, 9-year-old giant panda Lun Lun gave birth to a cub. According to Zoo Atlanta, which hosts Lun Lun and her mate Yang Yang, this was only the fifth cub born in the United States since 1990. Since four United States zoos host breeding pairs of pandas, this number might seem a little low.
If you want to help take care of pandas then you should tell people to start to care for pandas. You can tell the government to stop cutting down bamboo because that’s where pandas live and eat.
Are you looking for the perfect pet? I have one for you. It’s soft, it has a yellowish color and has bright orange cheeks. It’s not Pikachu, it’s a cockatiel! Cockatiels are the second most popular pet bird in the United States (after parrots). It’s not just because they are cute but because of the three C’s and those are easy to care for, cheap, and compatible for all ages.
It’s very easy to take care of cockatiels. Cockatiels can be left alone for a long time. This means if you are out of town for the weekend then you won’t have to get a pet sitter. They take care of themselves. They only need to get fed once every 2 to 3 days and their cage only needs to be cleaned once every 2 weeks. Another reason they are good pets is you won’t have to spend extra time walking them. They are happy exercising by themselves inside or out of their cage. Cockatiels like walking around inside the house, out of their cage while you pursue a quiet activity like studying or reading.
Another reason cockatiels are the perfect pet is because they are cheap. Of course buying one is about $100-$300 but after that, you will have nothing to worry about. The first reason is cockatiels get sick very rarely so you won’t have to pay for the vet often. Also, cockatiels don’t need check-ups or shots whin big bags last for a long time. Also, you won’t have to buy toys for them because they keep ich can be very expensive. Cockatiels do not eat much so the food which are cheap and come themselves entertained with anything around them. They don’t need toys to gnaw on to help their teeth (or beak) or climbing structures to be up high.
Whether you are 5 or 105, you will always love these nice animals called cockatiels. Cockatiels are smart so they are very easy to train. Kids will have fun teaching them do tricks. Kids would be amused seeing cockatiels learn simple tricks like stepping up and down and bow their head and some complicated tricks like somersaulting and saying their name. Also, cockatiels are quiet so if some families have babies who are afraid of loud noises then these birds are perfect for them. Cockatiels are also good for seniors especially if they live alone. They are good companions for them because they don’t need much attention but they can be there to keep them company. Seniors will also like the cockatiel’s quiet qualities.
Still not convinced that cockatiels are the perfect pet? Well just ask the millions of people who own them today and they will change your mind. They will tell you about the three Cs and other reasons that make cockatiels the perfect pet.
Could you imagine life without cell phones, tablets, or calculators? These are all computers. They are important part of our daily lives. Here is some information about computer history.
What computers are
So what are computers? They are defined as devices for saving and processing data. They were created initially to calculate math problems. Charles Babbage was the first one to invent the computer. It was a mechanical computer but he never managed to completely build it. The first digital, electromechanical programmable computer called Z3 was built by Konrad Zuse in Germany in 1941. Another fact is that the first computer mouse was made out of wood
First Modern computer
First modern, electronic computer was called ENIAC (Electronic Numerical Integrator and Computer) and was built in 1946-1947. It took as much as 1800 square feet of space. Early computers often stopped working. Sometimes it was caused by bugs. Not the software errors but actual insects that got trapped in these machines.
Nowadays, people have much smaller and faster computers And now they are not just used for calculating math problems They are to look things up, to upload pictures, to print and to help us in our daily lives.They are also getting more powerful. But about 6,000 computer viruses are released each month. That is one of the down sides of computers. But according to Moore’s law, computers get twice as fast every 18 months.
One thing is sure, it looks we will always use computers in our daily lives. I typed this homework on a computer, but who knows, maybe in few years, a computer would be able to write it all by itself.
Instead of walking, you are hopping. Instead of hands, you have paws. Instead of smaller ears, you have big, furry ears. What kind of animal could this be?——-you guessed it, it’s a kangaroo!
Kangaroos are famous for their large, powerful hind legs that they use for hopping. They are the only large mammal that uses hopping for locomotion. Besides that, kangaroos have another fun fact. They are marsupials. Marsupials are a group of mammals that carry their young in their pouch. Kangaroos are very different from other animals.
The Dangerous Journey
The newborn called a joey looks totally helpless. Yet, it manages to make its way to the pouch without any help from its mother. What an amazing feat a tiny creature can do. Clinging to its mother’s fur Joey climbs slowly to its mother’s belly to reach the warmth and safety of the pouch. The journey only takes a few minutes.
Life in the Pouch
Whenever a kangaroo is born, they go to their mother’s pouch. Safe in the pouch the joey clamps onto one of four teats that give life-giving milk. The teat swells to fill the mouth and works like an anchor, holding the baby firm so that the baby does not fall out as it’s mother hops around. Fed by the mother’s milk, the joey grows quickly. It’s eyes and ears open, it’s fur starts to grow, and it’s strong back legs develop. It starts to look more like a young kangaroo. After a few months, the joey takes it’s first peep out of the pouch. Soon it will be able to venture into the outside world the second time.
Leaving the Pouch
At the age of six months old, the red and gray kangaroos leave the pouch for the for the first time, as their mother’s tip them to the ground gently. Some kangaroos leave the pouch when they are eight months old and still suck milk for three to four months old. Others leave at eleven months and still suck the milk until they are eighteen months old. At first, the joey spends only a short amount of time on the ground before getting back into the pouch. The young animal moves awkwardly at first, but soon it learns how to hop on its hind legs like its mother. Their mother teaches them how to feed and take care of themselves.
Kangaroos are very interesting and unique animals, not only because of their hopping, but also because of the way they reproduce. Besides carrying their babies in the pouch female kangaroos are considered to always be pregnant. When one baby is ready to leave the pouch a new one is ready to climb back in it. Isn’t it amazing!
Have you ever wondered about National Parks? How many are there? What are they called? Where are they? Why do we have them? Why should we care about them? Why should we protect them? Well now I’ll tell you just read on and this article will answer those questions.
Did you know that since we are in the 4th grade we get to go to each National Park, with our family, for free? So why don’t you take a trip some time? A national park is scenic or historically important area of countryside protected by the federal government for the enjoyment of the general public or the preservation of wildlife. Commercial exploitation of natural resources in a national park is illegal.
There are 61 national parks in the United States. California has the most (nine), followed by Alaska (eight), Utah (five), and Colorado (four). Some popular national parks include Yellowstone National Park, Yosemite National Park, Grand Canyon National Park, Acadia National Park, Everglades National Park, Grand Teton National Park, Glacier National Park, Zion National Park, Denali National, and Mesa Verde National Park.
The largest national park is Wrangell–St. Elias in Alaska: at over 8 million acres (32,375 km2), it is larger than each of the nine smallest states. The next three largest parks are also in Alaska.
In 1906, President Theodore Roosevelt signed the Antiquities Act, which gave presidents the authority to create national monuments to preserve areas of natural or historic interest on public lands. The purpose of the Act was largely to protect prehistoric Native American ruins and artifacts.
All of these parks are holding onto something special. For example, places in California like Joshua Tree and Red Wood National Park are home to trees that grow nowhere else on the planet we know as Earth. Joshua Trees can only be found in Joshua Tree National Park. Same with the Redwoods. You can only see them in Redwood National Park.
We can help to preserve our national parks by purchasing a reusable water bottle or replacing our incandescent lights with CFLs or LEDs. These are some other rules you can follow to help and protect and preserve our national parks so our great great great great great great grandchildren can visit these amazing places:
Try To Put Fewer Greenhouse Gasses In The Air.
Reduce, Reuse, Recycle.
Walk, Bike, Carpool, or use Public Transportation.
Shorten Your Shower.
Use Less Electricity.
Replace Your Incandescent.
I hope you enjoyed this article and I hope you decide to visit a National park. I personally suggest Joshua Tree National Park. It is my favorite one because of the cool animals such as the chuckwalla. Also, the bouldering opportunities are endless. So if you like bouldering and wildlife go visit Joshua Tree National Park.
Imagine yourself as a copepod floating in the ocean seagrass among clown fish, puffers, and dozens of other sea creatures, when you realize you’re being hunted by a delicate slow poke seahorse who only swims five feet per hour. Copepods can escape from their prey very fast, so fast that the reach speeds that are the same as a human jumping 3000 miles per hour. Do you think that would be fast enough to escape a hungry seahorse? Not quite!
Best Ocean Predator
A seahorse’s favorite food to munch on is a copepod. Copepods are part of an animal group called crustaceans. Copepods are not only fast but they can sense vibrations from an oncoming predator and when they do sense those vibrations they get out of there speedy quick but seahorses can still catch those speedy copepods. Here’s why. Seahorses have a very unique shaped head with a feature above their nose that helps them make no waves and vibrations in the water when striking and then they suck up the copepod. This happens so fast that you cannot even see it without a very slowed down camera. If the copepods do sense the seahorse and try to bolt, the seahorse starts pivot feeding. Pivot feeding is where seahorse rotates their snout at high speed and then sucks in the copepod. This makes the seahorse one of the most successful predators in the ocean. I bet you thought it was sharks? Sharks are only successful at catching their prey fifty-five percent of the time. Seahorses are successful in catching their prey ninety percent of the time. Seahorses have to constantly eat to stay alive because food quickly passes through their simple digestive system. They have no teeth and no stomach. Since seahorses do not have teeth they have to suck in their prey and swallow it whole.
We talked about seahorses unique ability to catch their prey very fast and how successful they are. Another unique thing about the seahorse is that the male gets pregnant, carries the eggs and gives birth instead of the female. Seahorse males and females have a courtship. This is like dating. Before
they breed they court for several days by dancing in sync for eight hours and swimming side by side while holding the same strip of seagrass with their tales. During this time they sometimes change color.
Seahorses are usually found in shallow, tropical, and mild saltwater. They live in secure areas such as estuaries, coral reefs, and seagrass beds. Seahorse species are found in the Pacific and the Atlantic waters all the way from North America to South America. Species are also found in the European and Mediterranean waters.
If you like seahorses as much as I do, go down to the Batiquitos or San Elijo Lagoon and you might see them. Seahorses, as slow and delicate as they are, are quite unique and skilled at catching prey. Some seahorse species are endangered because in some countries they are hunted by humans to eat and they are also hunted for aquariums. Seahorse does not do well or live very long in an aquarium. I saw one in a tank when I recently went to a seafood restaurant for dinner. I thought it was very neat to see them but now after reading more about them, I feel sorry for the ones in the fish tank. Pollution is another reason for the threat to seahorses. We should all be doing our part to keep nature clean. I am going to the beach clean-up soon. Ask me how you can join in on it! I guarantee that you learned something about seahorses that you never knew before. Seahorses are not only cute but very interesting and I hope my article was too.
Close your eyes and imagine leading your team to the NBA finals. Your team is tied 62-62 in the 4th quarter of the last game. There are 5 seconds on the clock. You dribble it fast down to the other side of court to not waste time. You make a few bounces and then shoot it from the 3 point line over the point guards head. You shoot and then…YOU SCORE!
Basketball has been popular for a long time and it is the 3rd most popular sport in the United States. Basketball was created in 1891 in the YMCA (Young Men’s Christian Association) in Springfield, Massachusetts by James Naismith.
There are 5 positions in basketball. The positions are: the point guard, shooting guard, small forward, power forward, and the center.
There are types of actions that the players cannot do. They are called fouls. These are different types of fouls: hanging on people, punching and slapping, shoving and knocking them over. Specifically, if you touch them, the ref will call it a foul. The travel is another one. It is when you hug the ball and running with it without dribbling it. A double dribble is when a player catches the ball then dribbles it again.
Here are the two most popular leagues of basketball: NCAA (National Collegiate Athletic Association) and NBA (National Basketball Association).
There are 30 teams in the NBA. They are divided in to the Western and Eastern conference. Each conference has 15 teams. Each team plays 82 games in the regular season. The court is divided in 2 halves.
There are awards in basketball. This year all star Kevin Durant won the 2018 NBA finals MVP (Most Valuable Player) award. James Harden won 2018 all around MVP award.
There are championships in the NBA and NCAA. In 2019, it was Virginia vs Texas Tech in the NCAA finals. Virginia won. Meanwhile in the NBA, the playoffs are going on right now. This past year Golden State Warriors won the NBA finals against the Houston Rockets. In the playoffs, there are series. Each series is 7 games long. The first team winning 4 games is the winner.
Many people argue who is the GOAT (Greatest Of All Time). Most people say Michael Jordan and I agree with that. Michael jordan has led his fearsome Chicago Bulls along with his sidekick, Scottie Pippen to six NBA finals. Clearly, they have won all six. The Chicago Bulls dominated the 1990’s.
If you read this, this will help you get to learn more about basketball, how you play it and its rules. If you get the chance, play basketball.
It’s a Saturday morning and you race downstairs to see the box of Legos you’ve wanted to start on for days and you finally get to build it! You rip open the box, take out the instructions, pour the Legos out of the bag and onto the floor and you start building a big Lego spaceship! As you build, you stop to wonder: What is a Lego? Who came up with the idea of making Legos? How are Legos made?
Ole Kirk was the person who came up with the idea. In 1957, his idea became real. The reason why Ole Kirk came up with the idea was because in 1932 his wife died and he was left to raise his four children alone. He started to think about making toys that his four sons would love. First, he started making wooden toys like ducks, vehicles, and cats. Then, he started making plastic toys like cars, trucks, and binding bricks. Binding bricks are an early design of what we know are Legos today. Binding blocks have slits on each of the shorter sides and Legos don’t.
If you were wondering what is a Lego, it’s a building block that has studs on the top and tubes on the bottom and can be built and arranged into anything imaginable. You can use two eight-studed bricks in twenty four ways, three eight-studed bricks 1,060 different ways, six eight-studed bricks 915,103,765 ways, and with eight eight-studed bricks there are endless combinations. There ten Lego features that define a Lego but 3 of them I think are the most important. The first, is unlimited play potential. I think this feature is important because you couldn’t play soccer all day long, but you can with Legos. The second, is year round play. I think this is an important feature because you couldn’t play soccer all year round but you can with Legos. The last feature is development, imagination, and creativity. I think the final feature is important because you’re learning how to follow instructions and when you build things on your own your using your imagination.
Did you know that today, the Lego factory makes about 4 million bricks an hour? There are 16 steps in making Legos. Legos start their life as little plastic granulates or plastic rice grains. They are melted between 446 degrees F and 590 degrees F. Then, they pour the melted plastic into molds. The bricks travel on a conveyor belt into a crate and to a truck that ships the crates to the packing, assembling, and decorating department. The assembly machines attach the arms to hands and tires to wheels and so on. Printing machines add faces to heads. The packing department send bags of elements or Legos and books into boxes. Finally the boxes get packed and are shipped to stores.
I hope you learned some interesting facts about Legos. I even have experience with Legos. I have a whole tub of Legos. I think Legos are fun to play with, are for girls and boys, and fun for every age. I think Ole Kirk wants you to get a tub of Legos so you can have some fun and build huge creations like big spaceships, cars, trucks, other vehicles, and lots more.
You are standing in the shade under the beautiful cacao tree in hopes that a foot long pod will drop off the tree and into your hands. When it does you run, skip, and leap to your parents. You say, ‘let’s make chocolate!’ Chocolate tastes amazing but how is it made and what is it’s history?
Chocolate comes from cacao trees. These trees grow in tropical rainforests full of exotic birds, animals and flowers. They grow under the shade or canopy of the other trees around them. The beautiful cacao tree grows clusters of flowers and football sized pods. Inside these pods is white pulp. If you dig deeper down you will find dozens of rows of chocolate seeds! Once the chocolate seeds are gathered they are fermented, dried, roasted, shelled, and crushed into a smooth paste from which that sweet and melty chocolate bar is made.
The Maya Indians of Central America might have begun using cacao seeds as early as 600 BC. The Maya built a great civilization that included huge temples, hieroglyphics, and a passion for chocolate. From remains of hieroglyphics, we know that the Maya loved chocolate very, very much. During their religious holidays, they offered chocolate to their Gods. The Maya did not eat chocolate, they drank the sweet sensation out of carved pots. The Maya flavored their chocolate with chilly, flower petals, and vanilla. The Aztecs, who lived around 1500 AD used many of the same chocolate making strategies as the Maya. Just as the Maya had offered chocolate to their Gods, the Aztecs did the same.
Spanish explorers came to Central America in the late 1400s in search of gold. That is when they were first introduced to chocolate. Spanish Conquistadors adored chocolate. One Spanish Conquistador named Hernando Cortes, called chocolate the divine drink. The Conquistadors drank the sugary sweetness both hot and chilled. Chocolate first arrived in Europe in the mid 1500’s. But it is not known who brought it there. At first the Europeans gave chocolate mixed reviews. For 2,000 years chocolate was a drink only served to the upper classes. Hundreds of thousands of African American people were kidnapped and forced to work on sugar and cacao plantations.
This is an open Cacao pod.
Around the late 1800’s there were many advances in chocolate making. First came Daniel Peter who invented milk chocolate. He added evaporated milk to a mixture of liquor, cocoa butter, and sugar which created milk chocolate. He got this recipe from Henry Nestle. In the 1920’s Milton Hershey began to bring chocolate to the public in a grand way. He sold hundreds of thousands of chocolate bars at prices most people could afford. In the 1920’s many candy shops made their own chocolate. World war one gave chocolate a boost. American troops were given chocolate as an energy boost.
From cacao trees to delicious candy bars and from its beginnings in Central America through Europe and to the United States, chocolate has come a long, long way. According to the Farmers Almanac more than 58 million pounds of chocolate candy is sold during Valentines week. But Halloween takes the top spot as the number one chocolate candy holiday. 90 million pounds of chocolate candy is sold during Valentines week and Americans consume on average over 12 pounds of chocolate each year. What’s your favorite kind?
