Students explore the energy changes from a liquid to a solid. They model the arrangement of a solid and the change in states due to changes in energy using desks and chairs. Assessment questions are provided in lesson plan.

Students investigate what matter is and how it changes states.  In this physical properties lesson, students examine the vocabulary database and identify the characteristics of the three phases of matter.  Students perform a...

Students examine how a hot air balloon works. In this hot air balloon lesson, students do an experiment to test the effects of heat on density. Students make their own hot air balloon and act out how nitrogen moves when turned to a liquid.

Third graders study different bodies of water and how they fit into the water cycle. They explain that materials exist in different states (solid, liquid and gas) and change from one to another, that there are systems, order, and...

Pupils describe the motion of solids, liquids and gases. In this chemistry lesson, students describe how temperature affect motion of the particles. They determine the physical properties of each phase.

Students analyze earth science by creating a frozen treat in class. In this heat transfer lesson, students discuss how matter is transformed from solid to liquid and liquid to gas when energy is removed from the equation. Students...

Students explore liquids and solids by conducting in class experiments. In this matter lesson, students define the properties of matter and how heat can change those properties. Students experiment with heating objects such as butter and...

Learners explore matter by conducting an in class demonstration. For this liquid mixture lesson, students identify the difference between a solution in which a solid dissolves into liquid, and a suspension where the solid doesn't...

Third graders rotate between three property stations, the solid station, the gas station, and the liquid station. They experiment with each activity until the teacher gives the signal to change.

Pupils explore matter by conducting an in-class experiment. They experiment with water's various forms by melting and freezing water, identifying its new shape. These observations are recorded to supplement later discussion. They also...

Young scientists explore Earth elements by conducting an experiment. They define water vocabulary terms such as condensation and precipitation. In addition, they conduct a water experiment in which they build a terrarium, so they can...

Use the accompanying presentation and colorful technology sheets to introduce your class to the 10 different energy technologies. Connect kids to an interactive computer tool that allows them to combine different types of power...

Students explore energy by researching fuel usage on Earth. In this fossil fuel lesson, students define fossil fuels, the energy created by burning them, and the impact on the environment when using them. Students conduct pollution...

Students investigate the different states of matter by experimenting in class.  In this matter lesson, students participate in a lab activity moving from one station to the next creating different formations of matter....

Students explain how the elements are arranged in the periodic table. In this chemistry lesson, students determine the subatomic particles for certain elements. They research the physical and chemical properties of an element they chose.

Learners explore matter. They use a formula to measure the volume of matter.
