Science In A Van

We had some people who work at Science in a Van to come and teach us heaps about science.
This was fun and educational for all of us and interesting to watch.

Potato Spud Gun Experiment

For Science today we made potato spud guns. And its not the first time we have done this experiment, we have attempted to do this experiment before. And we do it is by getting a straw and stab it in your potato, then you take and you will see it has so potato in the straw. Then repeat the step on the other side of the straw, then grab something like a tooth pick and then push the potato towards the other side where the other potato is, but make sure that you're not poking a hole though the potato. Then if their is hole in the straw, the experiment will not work because of how this experiment works. How it works is after you do that potato part their is air in the space of the potatoes so when you push the potato towards the potato 2, it will push the air to potato 2 and the air has no where to go so it pushes potato 2. And then potato 2 popes out! And we recorded how far it shot and who got the best shot.

Animal Classification

Today in topic we learned about animal groups. There are 2 types of animals, Vertebrates and Invertebrates. Vertebrates have a spine, so for example birds are Vertebrates because they have a spine. Invertebrates have no spine, so a jellyfish is a Invertebrate.

There are 5 types of Vertebrates:

Reptiles🦎

Reptiles are cold-blooded, which means they have to keep in the sun in order to stay alive. And they lay eggs.


Mammals🐻

Mammals are warm-blooded, so they tend to have a lot of fur and don't lay eggs.


Birds🐦

 Bird are warm-blooded like mammals, but they do lay eggs just like reptiles do.

Fish🐠🐟

Fish have scales like snakes do. Fish breathe air just like all animals do, but they take the oxygen from the water into their gills.

Amphibians🦎

Amphibians have one feature like a fish, they take air from the water into their skin.
