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...

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...

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

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

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 practice spending money by completing math word sentences.  In this economics lesson, students utilize problem solving strategies to complete word problems written on the board involving making purchases with money....

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.

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 discover the history of hot air balloons by watching one ascent.  In this physics lesson, students utilize a Montgolfier Hot Air Balloon from an earlier lesson and record the temperature, rate of ascent and the volume....

Young scholars explore schools during the Colonial period. For this American history lesson, students participate in a simulation of school days in Colonial America. Young scholars visit a museum and use the schoolhouse as a setting for...

Students use this USA today activity to learn about hurricane season. In this hurricane lesson, students study the map of the earth and hurricane science. Students complete discuss questions. Students draw a map of the United States and...

A video leads off this activity on fables, introducing the class to this important form of traditional storytelling. The group defines fable and hears an explanation of the origin of this type of folk tale. They summarize the story they...

Seventh graders identify the three types of rocks. In this earth science instructional activity, 7th graders model the rock cycle using crayon shaving. They explain how rocks change as they go through the cycle.

It is impossible to cool down a glass of water by adding ice. Young scientists explore heat transfer through videos, experiments, and interactive games. They quickly catch on that the water melts the ice and things aren't always as they...

Students are introduced to invasive species and how they affect the ecosystems they now occur in. They explore the basic life histories of several invasive species that are of regional and or national importance. Pupils investigate how...

Students investigate how Newton's Third Law affects vehicle design. In this Newton's Third Law instructional activity, students use a web site to research Newton, his third law, and how to design a vehicle that uses a balloon for power....

Learners explore the functions of the heart and how it needs to work hard and rest. They play the "Wise Owl Says" game.
