SCIENCE DAY!!!

We were measuring how heavy the clay was. 

We melted big lumps of wax.

On Monday we had a Science Day. We rotated around to all the fourth grade classes. In Mrs. Ricci's class we proved that air has mass and takes up space by doing science experiments. One of them was blowing air under a cup full of water and the water level went down because the air forced the water out of the cup.

When we went to Ms. Miller's class we learned how the solid state changes into a liquid state. We learned how ice(a solid) can change into water(a liquid). Heat is what makes a solid melt into a liquid.
If a solid melts into a liquid the will still have the same weight.We learned that any liquid can change
into a solid by freezing it because she froze olive oil.

In Mrs. Koenig's class we learned how solids can change into a liquid and back to a solid.  To change a liquid into a solid you have to add cold and to change a solid into a liquid you add heat. Once a liquid stays out to long it starts to turn back into it's solid state because it cools off.

When we went to Mrs. Cioni's class we learned that changing the shape of a solid won't change the solid's volume. We used a graduated cylinder full of water and put a piece of clay in the graduated cylinder. The clay displaced the water and we were able to measure the volume of the clay.  Then we changed the shape of the clay and put it back into the water. We learned that changing the shape of a solid doesn't change the volume of the solid.

We had a fun time at all the classes doing science experiments. We learned a lot and wish we can do it again.
