Introduce your students to the scientific concept of sink or float. This hands-on experiment allows them to see which objects sink and which float. The concepts taught will be solidified with the completion of worksheets.

What do a bicycle and a car have in common? They both move using the simple machine wheel and axle. In this lesson, students learn about how this simple machine works, and will identify objects that use a wheel and axle.

Sink or float? This simple lesson has students guess the densities of different objects and place them into water to test their predictions.

Walk, sleep, run, eat! We're constantly using energy, whether we're moving or not. In this lesson, students learn how their bodies are constantly converting potential energy into kinetic energy and kinetic energy back to potential energy.

In this lesson, your students will explore the properties of solids and learn to describe them in various ways.

This hands-on lesson will get your students to investigate some mystery liquids, and they will have to use their observational skills to figure out what they are.

Use this lesson to show your students the different types of solids, liquids, and gases. Show them how a solid turns into a liquid and how a liquid turns into a gas by using real life examples.
