In this math lesson, learners analyze the density of liquids in order to explore linear functions.

Learners set up three different bowls, each with a different mass of oatmeal. Learners monitor the temperature of the oatmeal and find that larger masses take longer to cool.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

Learners build simple catapults and use them to launch cotton balls.

Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.

In this activity, learners determine the elastic and plastic properties of different types of metal wires.

In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).

In this chemistry activity, learners discover that the weight of the product of combustion is greater than that of the starting material.
