High schoolers trace a molecule of water through the water cycle including each of its three loops. They describe why evapotranspiration demands the largest portion of total precipitation falling on a forested watershed.

Students take a walk around the school grounds to discover the diversity of life that exists there.

Students research a frog's life cycle and habitat using books, the Internet and lecture. Students make origami frogs, write letters to Toad from Arnold Lobel's "Frog and Toad" and participate in a simulated camouflage activity.

Learners study chemotropic sybioses and chemotropic nutrition. In groups, they complete a Chemotrophic Species Investigations (CSI) Worksheet.

Tenth graders role-play as members of the food chain. Sticky tables acting as polluting factors are introduced and members of different trophic levels suffer varying degrees of damage due to those pollutants.

Learners survey and describe a stream ecosystem. They sample the benthic macroinvertebrate populations of a given stream and determine community structure through the use of the Chandler Index and a species diversity index.

Students study natural habitats, aquatic life, renewable and non-renewable resources. They discuss conservation efforts for sea otters and desert toad in this units.

Students build a soil erosion model to study the importance of soil conservation. They investigate how land forms from both constructive and destructive forces.

Students use egg cartons to construct models of coral colonies showing many aspects of the coral's natural history - including the structure of coral polyps and the coral colony's colonial life style.

Middle schoolers identify organisms of a benthic community. They place the correct organism in the correct community and practice using marine terms. They play this game like a game of bingo.

Students examine the role of carbon in the oceans and how phytoplankton determine the levels present. In groups, they practice measuring primary productivity using two methods. They use the internet to research the role of phytoplankton...

Tenth graders organize information to explain how photosynthetic bacteria contributed to climatic changes that happened on Earth. Students create a timeline by using a storyboard to tell the story of the change.

Seventh graders can go outside and explore the organisms that live in the environment outside their door. This is a wonderful opportunity for students to examine the world around them with a new perspective. This activity will increase...

Students discover the importance and how to change the water in an aquarium. As a class, they review the types of impurities that are found in water and discuss how to keep the tank as clean as possible. They develop a water change...

Sixth graders listen to music as they reflect on a time they told the truth without hurting anyone. Students listen to a story about a person who falls from a roof and breaks his leg. The person lies about how it happened. Students...

Students engage in a laboratory instructional activity in order to increase understanding of the impact of phosphates at the chemical and ecological levels. The lab exercise is completed with the goal of getting them to predict the...

Students investigate the different bioluminescent organisms. They use microscopes in order to make observations and draw what is seen. Students demonstrate they have studies the differences between the process of photosynthesis and...

Students discover and discuss the differences between prokaryotes and eukaryotes. Using a microscope, they examine various prepared slides of prokaryotic and eukaryotic organisms.

Eighth graders investigate the presence of talc in the geologic record. The different characteristics of talc is covered. The lesson includes background information for the teacher.

Students study the four groups of macroinvertebrates. In groups, they explore the characteristics of macroinvertebrates. Through playing a "Macroinvertebrate Simon Says" game, students discover the adaptations of the animals and their...

Students will observe the differences between photosynthesis and cellular respiration. Then they observe the links due to climate changes and relate how climate change affects their lives.

Young scholars research the geologic wonders of Yellowstone National Park. They locate the main geologic features of Yellowstone on a map of the park. Students write a description of the geologic features to be included on the map for...

Young scholars determine the changes in different types of water in a sealed container over time. They investigate how to measure dissolved oxygen, temperature, and carbon dioxide with calculator or computer probe-ware. Students...

In this unique writing worksheet, students complete two word searches by crossing off all the words hidden on each grid to uncover the mystery answers.
