Students investigate water pollution. They develop an understanding of the behavior of organisms, of the structure and properties of matter, and of natural and human induced hazards by conducting lab tests. They present their data...

Students conduct experiment with water striders by placing the insect in two different solutions and discuss their observations. They discover that weight and surface area are important factors in their experiment.

Students analyze water strider behavior. In this water strider lesson, students study the movement and feeding behavior of water striders. Students catch water striders and then generate scientific observations.

Students experiment with the concepts of surface tension. They participate in a number of different experiments that introduce them to surface tension. They work in a small group in order to conduct these experiments.

Learners make boats and race them. In this physics lesson, students investigate surface tension, molecules, and cohesion by competing in a class race with their boats. Learners experiment with liquid soap to see how much will make their...

Learners conduct a simple test to determine how many drops of water, rubbing alcohol and vegetable oil can be placed on a penny before spilling over. They consider how varying surface tensions allow for different amounts of each liquid...

Students explore food chains and food webs in a pond and identify common creatures found in ponds. They look for tadpoles, fish, mites and other creatures in a pond during a field trip for first hand research.
