In class we have been learning about chemical reaction.
I enjoyed seeing it all bubbled up
I found it challenging to write how it happened.
Have you ever wondered what makes things fizz, foam and froth?
A physical change is reversible, like how you can change ice back into water. A chemical change is irreversible. First, you put baking soda and a cup, then you add vinegar and it will explode. How did it happen? Well when you added the vinegar you changed the properties of the baking soda and that makes it explode.
Kia ora Charlotte,
ReplyDeleteWriting explanations can be tricky - that's where brainstorming the technical language can be helpful. Maybe you could add to this post and tell me about the carbon dioxide reaction that happened when you added the vinegar.
