This is a lab sheet where students explore a Physical Change. Students will make a Brownie Sundae and weigh each part of the brownie sundae, then add up the parts at the end to understand that the weight of the whole object equals the weight of the individual pieces of the object. The following things will be needed for this activity:
Brownie (sometimes I make brownies and show a chemical change, sometimes I buy store-bought brownies)
This is editable, so you can remove or add toppings as you would like to extend the activity.
