Students explain what is meant by term nuclear radiation, describe in detail electromagnetic spectrum, differentiate between ionizing and non-ionizing radiation, understand half-life of isotopes, differentiate between processes of...

What is reflectivity, and what does it have to do with the Earth's climate? As reflectivity is measured by albedo, scientists can gather information on Earth's energy balances that relate to global warming or climate change. Budding...

Get your classroom rocking with this four-lesson earth science unit. Through a series of shared reading activities and hands-on investigations, young geologists learn about the three types of rocks and the unique properties of each.

The water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

From types of rocks to types of weathering, learners gain knowledge on minerals, composition of soil, and the effects of weathering on Earth.

How did the earth become the mass that it is now? Your young scientists explore this question through the concept of density. Their inquiries consider the impact of gravity on the formation of planets. The culminating activity of the...

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...

While this is not the traditional, step-by-step lesson plan, it is chock-full of material that you can easily incorporate into your earth history unit. Its main purpose is to serve as a guide to using a three-part film, The Day the...
