Students become marine biologists, and their goal is to characterize the biological communities that live on or near the seamount in the Monterey Bay area. There, they must identify a mystery mollusk.

Plants need nitrogen to build proteins and nucleic acids to grow healthy stems and leaves. Though the Earth's atmosphere is made up of 79% nitrogen, the form of nitrogen found in the atmosphere cannot be used by plants. In this...

In this instructional activity, students expand their understanding of solid waste management to include the idea of 3RC (reduce, reuse, recycle and compost). They will look at the effects of packaging decisions (reducing) and learn...

Use the scientific reasoning and critical thinking to take an in-depth look at the basics of biology.

An illustrated article helps learners understand the water cycle and the distribution of Earth's water.

Make learning about Earth's biomes fun and easy with video clips. Learn about the unique Chaparral climate characterized by mild, wet winters and warm, dry summers.

Make learning about Earth's biomes fun and easy with video clips, photographs, and diagrams. Learn about estuaries, the water environments formed where freshwater from rivers or streams mix salt ocean water. [6:38]

In this activity, students collect, categorize, weigh and analyze classroom solid waste. The class collects waste for a week and then student groups spend a day sorting and analyzing the garbage with respect to recyclable and non...

In this instructional activity, students explore solid waste and its effects on the environment. They will collect classroom trash for analysis and build model landfills in order to understand the process and impact of solid waste...

In this lesson, students will learn about types of land use by humans and evaluate the ways land is used in their local community. They will also consider the environmental effects of the different types of land use. Students will assume...

This activity will allow students to bury various pieces of trash in a plotted area of land outside. After approximately two to three months, the trash will be uncovered to allow the students to investigate what types of materials...
