Life Below: Brrr!

What effects do temperature and carbon dioxide levels have on the zooplankton of Antarctica? This concluding lesson plan in a short unit on climate change and the ocean helps environmental scientists answer these questions. After...

Plants take cues from the environment—change in daylight hours and temperature—to complete their seasonal life cycles. Lesson four in the series of six has classes collect phenology data on plants. After taking initial observations,...

Pupils explore the important factors that affect habitat quality and the associated survival of migratory water bird populations. They discuss an organisms dependency upon a variety of habitats and habitat quality. Students play a game...

Discover the chemistry behind the color change in leaves. The lesson narrator describes how trees must recycle nutrients in the leaves before they fall off for the winter. The video breaks down the process and highlights the chemistry of...

There's something to look forward to in 2021 or 2022! Although the actual event occurred almost 2,000 years ago, the appearance of a new star will become evident from Earth in a few short years. The video instructor from the solar...

Students explain why dissolved oxygen is important in aquatic ecosystems. They evaluate the optimal dissolved oxygen levels for living organisms.

Students research the Earth's patterns of rotation and revolution, create a chart and graph of these patterns and use them to explain the causes of night and day and summer and winter.

Pupils become plants in an interpretive play that depicts what happens throughout the seasons in a rain garden. As you narrate, students bloom, flower, and go to seed accordingly. The lesson is first in a series of lessons written for...

Students investigate how plants absorb carbon dioxide during photosynthesis. In this biology lesson, students differentiate photosynthesis and cellular respiration. They discuss the important role of plants in the environment.

Young scholars differentiate between point and non-point pollution and determine how the different types of pollution are harmful to aquatic ecosystems. They complete a series of tests on a sample of "polluted" water and a sample of...
