Physical Change
1} A physical change is, when you can stretch something, pinch something, pull something, touch something, pound something and flatten something.
2} An example of physical Change is, when you fold a piece of paper and it is still the same piece of paper but just folded.
3} After watching this video, I have learned the following things about physical change. That you can burn things and it's like changing the shape of the thing. It can be done with food or other things too.
Nice examples of physical change, Anjana! Remember that when you burn something, it involves a chemical change because a new substance/s (e.g. carbon dioxide, ash) is created from burning. E.g burning wood results in a release of carbon dioxide into the air, then ash is left over once thewood has finished burning. Keep up the great work - I know you have done some great experiments at home - please share some photos of these to your blog so our class can see them too! (e.g. the egg experiment you showed me in our last Google Meet)
