Students explore the process of evolution. They examine examples of how homeotic genes may work and obtain gametes. Using a microscope, students observe the fertilization of sea urchins. They video tape the process and write a...

Fifth graders observe the video, Exploring Light and Color. They access a website to create their own light show. They conduct lab experiments to investigate refraction, reflection,and other light-related topics.

Ninth graders observe, compare, and classify various microorganisms using a microscope. They answer discussion questions, and record their observations on a chart.

Students collect and microscopically examine seeds from the school yard and neighborhood. In small groups, they draw and discuss the shapes of the seeds to determine each plant's method of dispersal. they also test two types of seeds...

High schoolers conduct a series of activities to explore the nature of cells. In this biology lesson, students observe plant and animal cells under the microscope and compare them. They differentiate osmosis and diffusion.

Students collect water samples and use a microscope to find bacteria in the samples. They categorize the different bacteria they find, determine the number of colonies there are, and predict how the bacteria levels might affect animals...

In this anatomy of the heart worksheet, students participate in a lab to describe the location of the heart in the body, identify a cardiac muscle tissue and trace the flow of blood through the heart.

Students discuss the importance of plankton in the ocean ecosystem. In this biology lesson, students identify the different types plankton by observing them under the microscope. They explain how plankton population affect global climate.
