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

Eighth graders design posters of working ecosystems using pictures from magazines. They label autotrophic, heterotropic, or saprotrophic energy sources, and identify predators and prey.

Young scholars compare and contrast the process of dehydration with the processes of freezing and canning. They predict energy sources that may be accessible in the future in different environments such as the moon and planets, most...

The sun will continue to rise in the east and set in the west, no matter what. The first lesson in a series of eight introduces the class to solar angles. It makes connections between a person's latitude and the angle of position of the...

Investigate the maximum power output of a photovoltaic panel with a lesson that introduces the class to the maximum power point. Individuals learn how to determine the maximum power point of a solar panel by using Ohm's law and the power...

Can you listen to Jupiter on a simple radio? Turns out the answer is yes! The resource instructs scholars to build a simple radio to pick up the radio waves created when the charged particles from the sun hit Jupiter's magnetic...

How temperature affects the efficiency of a solar panel is the focus of the third in a series of eight resources that presents how engineers are able to control the temperatures of photovoltaic panels. Class members find out how the...

What is the real cost of electricity? The real cost is not just the price you pay, but the environmental and economic costs as well. Scholars build, use, and judge the effectiveness of a turbine. They also investigate the...

Knowing the temperature coefficient allows for the calculation of voltage output at any temperature. Groups conduct an experiment to determine the effects of temperature on the power output of a solar panel. The teams alter the...

Concentrate to determine the best reflector design. Pairs use the engineering design process to build a reflector to increase the current output of a photovotaic panel. Teams arrive at a final design and present it to the class along...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

Just because we can't see it doesn't mean it isn't there! A growing concern for environmental scientists is toxic nanoparticles in our air and water. Young scholars conduct an experiment to demonstrate how these particles can cross our...

Fourth graders engage in a study of sound pollution at their school. After a class discussion on what noise pollution is, learners are asked if they think there are areas of their school or community where noise pollution is a problem....

Weathering is not necessarily a result of the weather. Scholars conduct an experiment to explore the effect of surface area and volume on the weathering process. They create their own sugar cube rocks using the same number of cubes—but...

You can't tell by the title, but this is a functional periodic table of elements. Incorporating bright colors, lucid text, and easily operated features, this application serves as a valuable reference tool for your chemistry class.

Learners explore renewable and non-renewable energy sources, discuss how each source was created, and identify and sketch out the cycle of energy for each renewable source.

Young scholars analyze the energy consumption of a household to see the amount of carbon dioxide they add to the atmosphere each year.  In this energy consumption lesson students calculate carbon emissions and discuss sources of...

Students explore wind power as a renewable resource.  For this wind power lesson students build models of wind turbines and experiment with different changes to see if it increases efficiency. 

Students explain that photosynthesis is a process that plants use to convert light energy into glucose. They summarize photosynthesis as a chemical process in which the plant uses carbon dioxide and water to form glucose and oxygen.

Fourth graders research sources of fossil fuels especially oil while determining how scientists take core samples from an Earth model. They look at oil consumption and production in the US and throughout the world.

Students use a meter to measure the energy used and carbon produced by electronics and appliances. In this environmental science and technology activity, students use a Kill-A-Watt meter to determine the electricity used by everyday...

Students examine energy use and the different construction materials used in their home.  In this sustainable choices lesson students study different materials and what a sound environmental choice would be. 

Fifth graders investigate situations that show how kinetic and potential energy are exchanged. They determine how friction is a source of energy transfer from kinetic to thermal energy by experimenting with a car and track. They answer...

Students explain how sunlight is converted to electricity. For this series of physics lesson, students study how varying the characteristics of the light source affect photovoltaic cells. They research their different uses in other...
