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...

Water is the only molecule on Earth that can naturally exist in all three states of matter. The interactive simulation shows different molecules changing states of matter with the addition or removal of heat. Learners then see how...

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...

Pupils conduct a mock trial focusing on environmental accountability of industrialized nations. As an example, they evaluate evidence provided on carbon dioxide emissions. They participate in a mock trial of industrialized nations by the...

Third graders observe and reproduce the water cycle in their very own classroom. A simple, yet very effective, demonstration on how water evaporates is observed by the young scientists. They make observations and sketches in their...

Teams of six to eight players imagine that they are driving in a vehicle and collect balls that represent carbon dioxide emissions based on their different activities. "Greenhouse Gas Guzzler" cards tell teams how many balls to collect...

Excite your classes with an exploration of the kinetic energy of electrons. Scholars watch as excited electrons transfer their energy between one another. The simulation models this transfer while graphing the change in kinetic energy of...

Plastic is fantastic! But, why does it behave the way it does? Science sleuths investigate the behavior of plastic in response to applied forces using an interactive. The resource allows users to bend a sample of plastic using three...

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 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...

Students illustrate the molecular nature of matter and show that chemical change involves alteration of molecules.

Third graders explain the basic healthy eating and physical activity concepts.  In this healthy lifestyles instructional activity, 3rd graders describe two main components of a healthy lifestyle, demonstrate two different types of...

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

Students investigate the economic and social changes that occurred in the High Middle Ages. They listen to a lecture and take notes, and in small groups compose a medieval charter and role-play its presentation to the class.

Do charged and neutral particles behave differently as they undergo phase changes? Science sleuths examine two types of attractive forces using an informative interactive. Pupils can vary the amount of Van der Waals attraction present...

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.

How do we clean up oil spills and other pollutants in the water? Explore water treatment strategies with a set of environmental science experiments. Groups remove oil from water, work with wastewater treatment, and perform a water...

Students simulate crater formation through a lab activity. In this space science lesson, students calculate how much energy is transferred during meteorite impact. They identify different factors affecting the size and depth of craters...

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.

Students role play molecules in a container as the container is heated to develop a definition of heat and temperature. They also observe demonstrations of conduction, convection, radiation, and phase transfer. Using these observations...

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 reflect on Abraham Lincoln's views of slavery.  In this United States History lesson, students analyze how things have changed in the United States over the course of their lifetime, then use this information as a...

Ninth graders explain how a scanning tunneling microscope works. In this chemistry lesson, 9th graders construct atomic models and simulate how their images appear under the STM. They discuss the limitations of their atomic model.
