If you look at a candle when it melts, it goes through a physical change. A physical change is when somethings changes but it's the same object. We did an experiment today and we tried to melt styrofoam but it didn't work. We tried with bowls that had a plastic surrounding it. We tried cups, and small pieces but it didn't work still. We poured nail polish remover over it but it didn't work. We even poured gasoline but it still wouldn't work. If we got a different kind of nail polish remover and a different kind of styrofoam I think it would work.
This experiment was also going through a chemical change. It's when an object changes and can't go back. When we played with it was warm because the water Mommy used was warm. We could make all kinds of shapes. I made the biggest necklace with it. You could stretch it, make shapes, tear it and then put it back together. It was fun!
