science learning story

Last week there was a big metal crate outside of Room 3. The big metal crate was called LAB IN A BOX. Lab in a box was a place where you can make things like rockets, explode balloons, pest trapping, mini beasts and dried ice. We got to choose three that we wanted to do. I chose dried ice, exploding balloons and rockets.

For dried ice we froze some fruit, flowers and marshmallows. Sue had to use gloves to put the things in the freezer because the ice was so cold that it could burn your hand. Then we smashed the flower, fruit and marshmallow. We found out that the reason why they broke so easily was because the middle was frozen and that is why it was so easy to break.

Next in the exploding  balloons group. Sue could not get the gas working so we did another thing called egg in vinegar, if you want to know what that is it is where you an egg and put some vinegar into a bottle and then in a day or two the egg should be bouncey.

The last workshop was my favorite because it was rockets. In rockets we had to get a little plastic bottle, we then had to make a mixture of water and baking powder, then we put that into a the lid of the little plastic bottle. Now we have one more thing to do we had to pour a little bit of vinegar into the bottle then we put the lid on and shook it a little bit and then it exploded. We noticed that if you put much vinegar in it and not enough baking powder your rocket will not pop and go very high. So we had a second try and we put a lot of the baking powder mixture and we filled the bottle up with about a quarter of vinegar. That made it go very high. The reason it exploded was because the air pressure was getting too tight in the small bottle it had to be in a bigger space but since it did not have a bigger space it popped the lid off and sprung into the air.

I think I was good at trying to guess the gas that Sue was showing us.

I think I was good at trying to stay focused on what she is talking about.

I think I need to work on trying not to sit next to my friends.

I think I need to work on trying to work with other people other then my friends.
