High schoolers investigate community issues with solid waste. For this mock trial lesson, students examine the issues of solid waste from an ecological and economical perspective. They will develop a mock trial which encourages...

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.

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...

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...

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...

Learners explore geometry by completing a math worksheet in class. In this shape identification lesson, students identify the characteristics associated with 15 solid geometric shapes. Learners identify patterns between vertices, edges...

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

High schoolers read a variety of letters from soliders who were on the front lines during World War II. After viewing an excerpt from "The War", they answer discussion and comprehension questions based on the letters and video. To end...

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.

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...

Four different-shaped and dyed pasta types represent four different alleles. Following a guide sheet, young geneticists practice randomly selecting alleles and discover the traits of the resulting offspring. This is a fun and solid...

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...

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 role-play as engineers designing wedge tools. They devise methods for shaping quarry rocks into pyramid blocks. Following a teacher demonstration, they use materials such as soap, clay, and foam for blocks and wood, plastic,...

During this game, kids become migratory shorebirds and fly among wintering, nesting, and stopover habitats. If they do not arrive at a suitable habitat on time, they do not survive. Catastrophic events are periodically introduced that...

Is it getting hot in here? Observe boiling from inside a beaker in an engaging interactive. Chemistry scholars heat and cool polar and non-polar solids and observe how molecules react to temperature changes. Your class' misconceptions...

Take it all the way back! Young scientists discover the changes that took place from the time Earth became solid to present day through an interesting interactive. The resource guides users through key events that have shaped our world...

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...

Credit can be confusing for teens, some of whom are already using credit cards. Clear up misconceptions with this group research activity which has a solid outline with a lot of room to adjust to your needs and resources. Groups are...

Students explore matter by conducting an in class demonstration. In 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 dissolve...

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...
