Supplies- 1 sheet of aluminum foil- Easy off oven cleaner- GogglesPurpose:We will use aluminum foil and oven cleaner to

understand how a chemical reaction works.

Practice Part 2“Easy Off Quick Lab”

Infer:List as many properties of metals as you canAnalysis:1. What property changes did you observe as

the reaction started to happen?2. What “clues” did you observe that indicated

a chemical reaction was happening?

Application

1.Use your notes to explain the difference between an endothermic and exothermic reaction.

2. Determine at what points did each reaction happen in your lab investigation.
