Students explore where insects live and how they have adapted to their environment.

Third graders observe insects in a number of habitats. They recognize which insect characteristics are adaptations to their habitats.

Students study the four layers of soil while identifying the substances that each level is composed up. They investigate the properties of soil such as color, texture, water retention and the ability to maintain life by growing a plant.

Students work together to collect soil samples from different locations. In the samples, they identify the macroorganisms and classify them. They identify the conditions that affect how macroorganisms grow. They also analyze and identify...
