This activity is a field investigation of plant succession stages, which students will gather evidence of the areas plant history.

This site helps students see how plants and animals interact to accomplish pollination. Students (Grades 3-8) identify plant and animal parts involved in pollination, connections between pollination and food production, relationships between pollinators and the plants they pollinate, and ways flowers have adapted to encourage pollination.

Help Sam the gardener in the Sunflower Greenhouse. Learn about plants and their parts, photosynthesis and energy. This lesson includes practical exercises. Good for grade 3.

The students will play a classic game from a popular show. Through this they will see the probabilty that the ball will land each of the numbers with more accurate results coming from repeated testing.

In this activity students learn about the life cycles of many aquatic insects and then on a fieldtrip collect and analyze samples of pond life.

This activity is designed to help students learn common names of pond life in Minnesota. To be most effective students should make a visit to the pond before participating in this activity.

This course serves as a description and critical assessment of the major issues and stages of developing a pharmaceutical or biopharmaceutical. Topics covered include drug discovery, preclinical development, clinical investigation, manufacturing and regulatory issues considered for small and large molecules, and economic and financial considerations of the drug development process. A multidisciplinary perspective is provided by the faculty, who represent clinical, life, and management sciences. Various industry guests also participate.

Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating to work. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.

Explore what makes a reaction happen by colliding atoms and molecules. Design experiments with different reactions, concentrations, and temperatures. When are reactions reversible? What affects the rate of a reaction?

In this video segment adapted from NOVA, learn about the critical role of flowers in seed plant reproductive biology.

In this video, students learn how scientific surveys of wildlife are performed at a site in Yosemite, California. These surveys, in conjunction with studies from the early 1900s, provide evidence that animal populations in Yosemite have shifted over time in response to rising temperatures.

This site examines misconceptions about herps (the collective name given to reptiles and amphibians), how herps have been viewed throughout history, and how reptiles and amphibians are similar to and different from one another.

This activity is a field investigation where students gather data, draw detailed diagrams, and write descriptions about living organisms and non-living things seen in a small school ground area.

This video explores the work of environmentalist John Hart, a Professor of Environmental Science at U.C. Berkley. In the Rocky Mountains of Colorado, Dr. Hart has established an experimental laboratory in which he has artificially created and maintained a 3-degree increase in surface temperature of a plot of land, and documented the impact on plant species occupying the plot.

This video segment features subsistence fishing and harvesting in the Northwestern US. The segment was adapted from a student video produced at Northwest Indian College in Bellingham, Washington.

Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. Relate the charges on ions to the number of ions in the formula of a salt. Calculate Ksp values.

This student activity engages the students' thinking by listening to a story, brainstorming ideas in small groups about how human activity or natural disasters could possibly impact an animal's environment, and then reinforcing that thinking using a board game called Save an Animal.

This lesson is a classroom and field-based activity where students learn about the parts of a flower through observation, journaling, and Observation.
