3. Intro We have explored and learned many things at the Shanghai Science and Technology. This Power point will show you what we learned at the fantastic museum.

4. Walrus There are 2 types of walrus. The Atlantic walrus and pacific walrus. There are more Pacific walrus than Atlantic walrus. The walrus kills animals with its long razor teeth. Not only that but they use their tusk to pull themself out of the water. Walrus eats organisms like shrimps, crabs, soft corals, sea cucumbers and clam. Walrus like to live on shallow water on icy floes. A walrus’ tusk is about 2-4 ft. They have skin that is very wrinkly which is like a armor to prevent being eating by predators like orca whales hunters and polar bears. Walrus can swim up to 22 miles per hour. A walrus’ has its whiskers not just for fancy looks but they can use it to sense for food.

5. Polar Bears The polar bear is twice as big as a Siberian tiger. When ice forms over the ocean, the male polar bear goes hunting for seals while the female polar bear takes care of their a cub. Polar bears are strong swimmers and can swim up to 6 miles per hour. Polar bears’ fur also grows on the bottom of there paw to prevent it from getting cold when touching something cold. Polar bear use their white fur to camouflage itself with snow. Polar bears mostly eat seals. There strategy of catching seals is by breaking a hole in the ice so when the seal comes up to take a breath, the polar bear will catch the seal.

6. The African savannah • In the African savannah, a deer gets hunted by a ferocious lion. Normally you would think they would be weak and almost extinct due to excessive hunting. But no! A deer can confuse the lion by madly running and jumping in all directions. • Hippos are also part of the African savannah and they can’t be ignored. They are like the kings of the savannah. They are very peaceful and only attack when attacked. They can only be brought down by a big pack of lions. Also an interesting thing about hippos is that they spend all morning in water but at night they sleep on land.

7. Cave Life Some animals somehow ended up living in dark caves. They had to do the only thing they can do: survive. In order to do that they must adapt. Their eyes start to become worse or even disappear completely! One example is the eyeless fish, which is kind of self-explanatory. This seems bad though. But if you were in a cave you actually wouldn’t care. And get this: you get improved smell and/or hearing. Win!

8. How does adaptation work? It all starts with these long DNA strands that are basically like storage systems that store each and every thing about you, not including the mental stuff. This determines what and how you are. If you are missing some then, oh well. Adaptation is kind of like this. To survive specific environments DNA will change accordingly. Then these are passed down to the children. That is how adaptation and DNA works. DNA

9. Another Fact! Did you know? The amphibians were the first of the land-dwellers. Sea animals developed into amphibians, half land half water animals. And those, make up the vast majority of our land-dwelling friends, and that includes us! Imagine me, a frog! Ribbit!

10. In our Chinese New Year assembly we had to do a zodiac project, and guess what? Zodiacs are animals! And we just talked about ANIMALS! Another minor point: we learned about body systems, animals have those too, and when William talked about DNA stuff, that has to do with the Nervous system How do Animals Relate to School

11. Spiders

12. Place Where Spiders Lives Spiders lives in almost every place on earth. The only place where there are no spiders are the polar regions, the high mountains, and oceans. Surprisingly, few spider species have invaded the ocean’s edge, living in rocks, and the coral crevices of the intertidal zone. Also, most spiders live in their own web except a few. A few spider live in trees like the tarantula or on the water, but not always.

13. Food Spiders usually eats insects like beetles or dragon flies, but some spiders like the tarantula can eat small birds like humming birds. Their food is only live prey. Also, spiders actually does not eat the prey. They drink the blood from their prey that they captured with a spider web. Spiders often increase there body weight by 50% with a good meal. Spiders can live for a long period without food. The record for a spider without food was 1 year (however, they do need moist conditions to prevent de-hydration).

14. Some spider legs can be as long as 200mm. • The smallest spider in the world is the web building spider. • Spiders has only 2 body parts. • All Spiders has fangs, most of them has venom in them. • Spiders can’t chew. • Lucky for us, most of the spiders poison is too weak to harm us. • You can fit 10 of the smallest spiders in the end of a pencil Facts about Spiders

15. How Spiders and School Relate Some spiders have a lot of dangerous venoms, and these venoms affect the body system: minor point, but still a relation. For example some venoms can make you act like a crazy madman and drop down on the floor. This affects the nervous system. Some others can stop your blood or does something to your blood: circulatory system.
