In this demonstration, learners observe as a bottle is placed on a table with wooden hoop balanced on top and a pencil balanced on top of the hoop.

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.

Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

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 use colored candy to represent subatomic particles and make a model of an atom (Bohr model).

Learners make a mobile model of a carbon atom using clay, wire, and pipe cleaners.

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.
