Students encounter three ecosystems for earth worms prior to performing an experiment. It will introduce students to one form of ecosystem as well as demonstrate how earthworms and the foods they eat affect the environment in which they...

Students summarize the steps of the scientific method. In this life science lesson, students explain the importance of varying only one variable at a time. They analyze possible flaws in their experiment.

Students compare and contrast different organisms characteristics. In this life science lesson, students design an experiment about plants and animals needs. They collect data and write their conclusion about the experiment.

Students perform experiments to examine whether trash can float, blow around, or wash away. The effects of these characteristics on the presence of marine debris in the environment are then discussed.

Learners record changes in an ecosystem. In this science lesson plan students make a hypothesis about changes in a terrarium. They record their observations. The learners conduct an experiment to test their hypothesis.
