Chemical and physical change
This storyboard does not have a description.
We learned about Chemical Changes and Physical Changes.
What did you learn about today in science class?
I have flying powers.
How are you dunking if you're only 5'1?
Ok. Now tell me what Chemical and Physical Changes are.
A physical change is the process of only changing the size, shape, temperature, or phase of a substance.
Now, a chemical change is the process by which new substances are formed through chemical reactions.
Some examples of a physical change are, evaporation or melting because they both can go back to their original form.
Do you have a good example for a chemical change?
Yes. If a wooden log is burned to ashes, it can't go back to its solid form, therefore it is a chemical change.
Oh, I get everything now. Thank you.
