It IS rocket science!

Fourth Grade

Fourth graders will begin to study more advanced concepts of earth science, engineering, health, and chemistry with these kits. Students will have many opportunities to perform exciting hands-on building activities and experiments during these units.

Earth Science

Students  explore the tools and techniques of meteorologists, geologists, and astronomers in this unit. As meteorologists, they gather weather data and interpret weather maps. As geologists, they learn to read the story of a rock and then how to identify it. As astronomers, they experiment with lenses to understand simple telescopes and then go on to learn about the latest advances in astronomy. See what’s inside the Earth Science kit.

Engineering Toys

Engineering Toys is a unit that covers the basic stuff of physics, energy, motion, and forces—but with a fun twist. Cotton ball catapults, tops, quiz boxes, and sound cannons are a few of the great toys that students take apart, build, design, and experiment with as they come to understand forces, forms, and transformations of energy and motion. See what’s inside the Engineering Toys.

Healthy Science 4

Four systems of the body are explored with models and activities. Students make lung models, watch digestion, check out bones, and explore their nervous system with tricks and treats. What is the role of smell in taste? Can you really hold your hand steady? Students will also get the chance to try and fool their eyes with some of the greatest optical illusions they’ve ever seen. See what’s inside the Healthy Science 4 kit.

Investigation Chemistry

Students get their hands on many different kinds of materials in this unit as they explore physical and chemical changes, measure mass with their own balance scale, and put their knowledge to work at the polymer lab. Students explore mass and volume as they find that sometimes 10 + 10 = 15 and sometimes 1 + 10 = 50 (milliliters, that is!). See what’s inside the Investigation Chemistry kit.


What does it take for a plant or animal to survive? What behavioral or structural adaptations does it need to get food, reproduce, and avoid being eaten? How do communities of animals and plants work together, and what happens when something goes wrong? Students try their hands at designing seeds, creating food webs, and classifying adaptations. We include a gel ant farm as a fascinating and easy way to observe up close how living things survive. See what’s inside the Survival kit.
