Celebrate the changing of the seasons with this collection of arts and crafts activities. 

The moon orbits Earth while the Earth is rotating, and the Earth revolves around the sun. This can be a tricky concept for young astronomers. Implement an activity that helps distinguish between the movements of Earth's systems around...

Proving microscopic structures exist is a difficult task. Learn how scientists did just that in the mid-1800s as they set out to identify the cellular structures related to genetics. The online lesson explains the collection of work that...

One ecosystem is home to numerous habitats—how diverse are they? Pupils interact with an online lesson to explore three habitats in a rain forest ecosystem. They discover connections between species and how they depend on each other for...

Not all dogs are the same just like not all finches are the same. An interactive online lesson helps individuals learn about the causes and limitations to biodiversity. The clickable sections describe the basics of the genetics of...

Keep within a water budget. Learners find out that less than 2.5% of Earth's water is available to drink—and that there is a fixed amount of water. Scholars read an interesting article comparing the available water to a game of Monopoly...

From the scientific method to the function of a cell, the eBook has it all. A useful resource provides a free biology textbook with a focus on context. The text begins with an overview of the process of scientific inquiry and biology...

Do you know the name for the biological study of interactions? A short presentation with accompanying worksheet introduces individuals to ecology. The materials offer a broad overview of the subject and the levels of organization to...

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...

Middle and high schoolers study significant people who shaped the 20th-century history and are introduced to database tools. Researchers use the Internet to research five 20th century history makers. They write a short biography of five...

Engage learners with an intriguing presentation on DNA and its role in organisms. Individuals see its structure, what genes are, how the code works, and then explore DNA replication. For advanced classes, the presentation introduces...

The climate at the equator is hotter than the climate at the poles, but why? The lesson goes in depth, explaining how the angles of illumination relate to the heating rate at different latitudes and seasons. Scholars use a strong lamp,...

One of the key objectives of Europe's Copernicus Earth program is to monitor the temperatures of the oceans and seas on Earth. Young scholars learn the effects of different heat capacities through two experiments. These experiments...

A greenhouse provides additional warmth and protection to the plants inside, but what if the greenhouse gets too hot? Pupils discuss and experiment with the difference between natural and anthropogenic greenhouse effect. They measure the...

What can fossils tell us about periods of extinction? Young scholars interpret fossil layers to make conclusions about changes in life during different geological time periods. They analyze the fossils for abundance and diversity as well...

Explore the food chains that support Arctic ecosystems. A class discussion on interdependence and the different roles plants and animals play in ecosystems provides learners with the knowledge to complete a worksheet asking them to...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...
