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.

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.

Show your class how combining two objects can create a new object in this hands-on science lesson. Students will learn why breaking apart an object doesn't change its mass.

Help your class gain a foundational understanding of matter by learning how to conduct inquiry and gain an understanding about the characteristics of gases. This lab will have your students amazed at what is really in the air.

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.

Help your students' reasoning skills grow with this activity that has them make educated guesses on whether or not an item will be attracted to a magnet.

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.

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

The science of matter becomes as fun as it is educational when George gets in the mix! After watching Curious George work with his 'floppafication' pot, students will learn about matter and force.

Mad scientists! In this lesson, your students will explore electrical circuits and engage in a hands-on activity to create them. They will identify the differences between parallel and series circuits.

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.

Your students will enjoy this hands on lesson where they make simple solutions and mixtures. They will have an opportunity to predict and observe solids that dissolve in water.

In this teacher-approved lesson, students will make and play with oobleck (corn starch and water), then write about their experiments. Young scientists will have a blast seeing their oobleck mixtures seemingly come to life.

Science can be sticky! This interactive lesson with an ooey-gooey ending will solidify your students' understanding of the states of matter!
