Mojo from our Class Dojo account has shared a very simple breathing exercise with me, which is very calming and is helpful if you feel worried about anything. He also sent me a picture for you to use if you are ever having a bad day, which everyone has sometimes.
Scroll down below for a special science lesson from Wiktor!
You can also try this experiment if you have a sharp pencil and a plastic ziplock bag like Wiktor has.
If you would like to try it yourself, click on the link for more information!
Thanks for showing us Wiktor!
