Curated OER
Water Strider Maze
In this mazes worksheet, learners examine the best way to help a water strider find the mosquito larvae through an adventurous maze.
Curated OER
Effects of Water Pollution on Aquatic Organisms
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...
Curated OER
Walking Magic
Young scholars 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.
Curated OER
Water Striders
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.
Curated OER
Break the Tension
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.
Curated OER
Spot the Differences
In this spot the difference worksheet, students analyze pictures of two
different water striders to see if they can find five differences between the
two.
Curated OER
Walking Magic
Students investigate surface tension using water striders. In this inquiry lesson, students develop a researchable question about the topic. They explain the environmental consequences of lowering water surface tension.
Curated OER
Water Unit
Students make boats and race them. For this physics lesson, students investigate surface tension, molecules, and cohesion by competing in a class race with their boats. Students experiment with liquid soap to see how much will make their...
Curated OER
Wet Pennies
Students 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...
Curated OER
Food Webs in a Pond
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.
Curated OER
Clay Ants: Insect Anatomy
Students examine anatomic structures in order to identify insects from other living organisms. They gain a level of comfort from anxiety when observing and handling live and pinned insects. They create clay models of an insect.
