NGSS Science and Engineering Practice: Asking Questions and Defining Problems

Each worksheet (there are 2 provided) gives students 8 interesting questions such as “Are people who wear perfume more likely to be bitten by mosquitoes?” and “Does feeding a horse sugar cubes give it cavities?”. Students will:

• READ each question.

• DESIGN AN EXPERIMENT that could be performed to test their hypothesis. They state the independent variable and dependent variable then describe controls that would need to be put into place.
