Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.

In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.

In this activity, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.

In this activity, learners conduct scientific research on multitasking. Learners determine if multitasking with media while doing homework affects their ability to successfully complete the homework.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation about the different causes of glacial melt.

In this activity, challenge learners to keep an ice cube from completely melting in 30 minutes. Learners engineer a box or wrap to prevent an ice cube from melting.

This activity (located on page 4 of the PDF under GPS: Sea Turtles Activity) is a full inquiry investigation into testing a repair material.

In this activity (page 26 of the PDF), learners make observations, formulate hypotheses and design a controlled experiment, based on the reaction of carbon dioxide with calcium hydroxide.

Learners build devices from rubber bands to test for invisible air pollutants.
