So, what are physical changes and chemical changes?

A physical change is when matter is changed but can be reversed.

For example: cutting paper

A chemical change can not be reversed and rearranges the structure of molecules.

For example: burning wood

Process

So, after you have watched The Magic School Bus video at this link : http://www.teachertube.com/video/get-ready-set-dough-347712

Use the video to answer this constructed response.

In the video The Magic School Bus, what happens when the baker puts the cake batter in the oven? Use information from your notes and the video to answer. write your response on a pice of paper.
