This is my last blogpost in sciennce :*( . I love 5 scienced the is so much different kinds of science. I am going to blog over the summer though. YAY!

I think the 5 is going to expand a little. I think the 10 is going going to expand even more. The 15 is going to POP!
The 5 mL was smaller than the 10 mL. But none of them exploded. : ( And the 15 mL got smaller then the 10 mL... I know what your thinking..... WHAT?

In science we got to pick what we were going to do for the rest of the year, I picked photo engineer. Photo engineer is when we toke pictures around the school and make it better. I picked it because I've always wanted to be an engineer. I think it did good because I thought of good ideas like nonsqueaky chalk. I think I did good at thinking of ideas. I didn't do good at writing about it. I learned that thinking of new ideas is hard. If I did this project differently I would take better pictures.

Matter is thing that takes up space. matter is made up of atoms. Everything is made up of atoms. Atoms are super tiny. Some states are solid, liquid, and gas. Every object has a melting point, a boiling point, and a freezing point. Some matter is made of different elements, this is called a mixture, but you can take the the mixture out and put back together. Air and water are even a mixture. A water is made is up of two hydrogen and one oxegon, that's why it's called h2O.

Are class today had to watch 3 BrainPops and wright about one of them. I chose the heat BrainPop to right about.
Heat is when molecules are exposed to energy the start to move because start to absorb it at this point they starting moving faster and bump each other. Temperature measures how fast they are moving and heat measures energy contained in an object because of molecules moving. The lowest temperature you can get the molecules is absolute 0° and at this point the are pretty much frozen. Heating an object causes it to expand because the molecules take up more space and if you get the object warm enough they can turn into a liquid and getter even more hot it can turn into a gas. Heat likes to even itself out. If you put a heater in a room it will heat up the room. Turn it off the the air won't be as warm.the are different ways heat can be produced. One way is solar energy like the sun. Another way is chemical energy stored inside gas. That is what I learned from the BrainPop on heat
