Here is the scenario:

Someone has broken into the Sugar Shack Bakery and stolen the secret ingredient in the Death by Chocolate Cake recipe! Using samples from the bakery and evidence found in the suspect’s car, you will help solve the crime.

In this investigation, students will observe and test five known substances to determine if a new substance is made. Then, they will use this information to determine the identity of the evidence that was found in the suspect’s car.

Through this investigation, students will identify materials based on their properties, determine if new substances are made, and therefore determine if a chemical reaction has occurred.
