Third Grade Classroom Kits

Students examine plants and animals to determine the function of structures such as teeth and beaks. These structures are related to the classification of animals and plants, an organism's ability to adapt to different environments, and its habitat. Students begin to explore how diverse living things are alike and how they are different.

The four lessons (and additional time to continue experiments) of this kit challenge students to design experiments testing how to keep foods fresh and which foods contain fats, proteins, and starch. They hunt for food preservatives, learn what "sell by" really means, and put together their own healthy body puzzle.

Students are constantly challenged to design tests, perform trials, and evaluate results as they explore magnets, pendulums, mixtures, materials, and light. From getting the iron out of cereal to solving a swinging problem for two friends to exothermic and endothermic reactions, students learn by doing science.

This unit starts with a look at space as students learn about the night sky and how to identify several constellations. Then time is spent learning about each of the planets and comparing them to each other. The focus comes back to Earth as students learn about our air and water, animals around today and those long extinct, and how our planet keeps changing quickly and over time.
