Second graders investigate the properties of solids and discover how to classify them. Using rulers, they measure various solids on display. In groups, they play an identification game where one students names a location, such as the...

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.

Need a solid resource for teaching about states of matter? Science scholars go with the flow in a simple interactive that shows how intermolecular attractions determine a substance's phase. Pupils take control of the level of attraction...

Which travels faster, light or sound? Scholars work in groups to simulate the ability for waves to travel through solids, liquids, gases, and through a vacuum. Then, they learn about the properties of a mystery wave and must determine...

Young scholars 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.  Young scholars...

Students examine how a hot air balloon works. In this hot air balloon lesson plan, 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...

What happens inside a melting solid? Prospective physical chemists observe a solid-to-liquid phase change at the molecular level using an inspired interactive. Pupils add heat to a close system, then monitor changes in kinetic and...

Energize your phase change lesson plans! Add a short but focused interactive into the mix and watch as pupils experience how states of matter react to changes in kinetic energy. The resource tracks the kinetic energy of a cold solid...

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...

Students describe the motion of solids, liquids and gases. In this chemistry instructional activity, 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 instructional activity, students define the properties of matter and how heat can change those properties. Students experiment with heating objects...

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...

Given a variety of rocks, junior geologists calculate densities and correlate them to Earth's layers. As a simulation of continental crust, they experiment with how materials of differing density float in water. Finally, they...

Students define trash, garbage, or solid waste, discuss ways of disposing of trash, list examples of biodegradable materials, and have trash relay race in order to sort trash into appropriate containers labeled biodegradable, reusable,...

There's more to melting than meets the eye! Junior physical chemists investigate the differences between specific and latent heats as a substance undergoes a phase change. Users remove heat from the system and observe changes in kinetic...

Students study the location of Earth's water and study the water cycle using a terrarium. In this water study lesson, students study a model globe for the Earth and find Alaska. Students locate the bodies of water and study an overhead...

Young scholars determine the differences between the crystallization of igneous and metamorphic rocks. They examine both liquid state and solid state crystallization.

Students observe earth science by examining results from an experiment. In this buoyancy lesson plan, students practice floating different items in two different liquids and identify why certain objects will float and others sink....

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 combine movement with science in this fun integrated lesson. When students are "liquid" they can "melt" or "ooze" at the end and when they are are "solids" they can "freeze" in a shape.

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...

Second graders analyze the effects of sunlight on a glass of water by using the thermometer to measure its temperature. They predict and measure the difference between water outside in the sun and shade and inside. They role-play a game...
