What do brown bears in Alaska's Katmai National Park need to survive? Pupils explore the unique habitats, diet, and survival needs of this animal. They predict the consequences of removing any integral part of the bear's survival,...

Water can travel from the highest mountain tops to the largest oceans. Using an interactive, young scientists trace the movement using an interactive online resource. They follow the water cycle by reading pop-up explanations on a...

Three activities make up a solar system lesson that features the sun, its light, and the shadows it produces. Scholars step outside to discover the changes shadows make at different times of day, take part in a demonstration of...

You are what you eat—or at least a part of what you eat. Budding scientists examine owl pellets to develop their own food webs. They use tooth and skull identification techniques to classify what they find.

Tag, you're eaten! A lesson on predator-prey relationships uses the game freeze tag as a model. Learners become either a predator or prey and play a game of tag as the prey tries to reach areas that house food and shelter. During the...

Using a guided instructional activity, pupils learn about what it takes to make a circuit along with a switch. They build a complete circuit under the direction from the teacher and identify each of the elements of the circuit. Scholars...

In this word search worksheet, students search and locate words as they relate to energy. Words can be found forward, backward, up, down and diagonally.

Students explore energy sources. In this science activity, students complete an interactive activity in which they choose the energy sources they will use to power a city. Students discuss renewable energy options.

Learners investigate forms of energy as well as light and sound. In this science lesson, students participate in hands-on activities that require them to evaluate how sound affects astronauts in flight. A video of this lesson being...

Students experiment with a vibrating ruler and a kazoo to study the different pitches and frequencies they produce. They create both high and low pitch sound waves. They examine how engineers use sound energy when designing electronic...

Students explore how sound waves move through liquids, solids and gases in a series of simple sound energy experiments. They describe how sound needs molecules to move and that changing the medium that it travels through changes the...

Students research how water is used to generate electricity. They investigate water's potential-to-kinetic energy transfer in hands-on activities about falling water and waterwheels. They take measurements, calculate averages and graph...

Young scholars simulate the distribution of nonrenewable energy resources using cookies. They determine how the world's growing population effects the equitable distribution of these resources. They look at how engineers work to develop...

Students experiment with heat. In this physical science lesson, students engage in hands-on activities to develop concepts related to heat. Students offer explanations for their observations using given vocabulary.

Students see that solar energy is the energy given off by the sun. They explain that when light energy is absorbed by objects it is changed to heat energy and that dark-colored objects absorb more light and store more heat from sunlight.

Students investigate solar energy. In this solar energy lesson, students compare how heat is absorbed in light-colored objects and dark-colored objects by making S'mores.

Students investigate chemical energy. In this physical science lesson, students blow on saltine crackers to demonstrate how chemical energy in food can be converted to motion. Students compare the saltine cracker experiment to how...

Young scholars identify wind and water as natural resources that create energy. In this natural resources and energy use instructional activity, students work in groups to construct a pinwheel, then explore the effects of wind and water...

Students cook with the power of the sun. In this solar energy lesson, students explore solar cooking as they apply scientific principles to cook s'mores.

Students use a selection of solar panels, lamps, motors, and an AA battery to get as many motors or lights to operate as they can in an allotted time period. For each successful arrangement, they draw a diagram of their setup, label the...

Students discuss energy. In this energy challenges instructional activity, students read about greenhouse gas emissions and global climate change. Comprehension questions from the reading are provided. 

Students explore energy by participating in controlled electricity experiment. For this static electricity lesson, students identify the different sources that can create energy and how static electricity can be created very easily on...

Students explore concept of how solar energy is gathered by solar panels and adapted to provide power to machines, disassemble solar powered calculator and explore component parts, and work in teams to suggest design enhancements to the...

In this sound energy worksheet, students predict what happens when bats bounce sounds off of walls to communicate. Students complete 2 questions.
