In this activity, learners construct a model of DNA to better understand the structure of DNA and protein synthesis.

In this activity, learners build a plastic emergence chamber (or use purchased "mini mosquito breeder") to observe and analyze the mosquito life cycle.

In this activity, learners explore rocketry and the principals of space flight.

In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

In this technology activity, learners build simple circuits, design soft circuits using conductive thread, and then sew switch-activated circuits.

In this activity, learners explore how engineering has impacted the manufacturing of canoes over time, including the development of new, durable, and lighter materials.

In this activity, learners explore how the pendulum has been a reliable way to keep time for centuries.

In this activity, learners apply Ohm’s Law to construct voltage divider circuits. Learners discover how to read resistor codes and calculate resistor values.

In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

In this activity, learners examine the different materials gardeners add to their soil, and discuss how these materials are important for plant growth.

In this activity, learners explore how boats are engineered to achieve speed.

This interactive demonstration reintroduces learners to three states of matter (solid, liquid, gas), and introduces them to a fourth state of matter, plasma.

In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).

In this two-part activity about the connection between the lupine plant and butterflies, learners first read "Miss Rumphius," a storybook about lupine by Barbara Cooney.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

In this activity, learners use household materials to investigate and explore their ability to smell an odor.

In a series of three experiments, learners explore the basics of biotechnology using self-locking plastic baggies. Each experiment demonstrates a phenomenon or principle of biotechnology.

In this activity, learners explore the engineering behind the conveyor belt and consider the impact this invention has had on transportation and the coordinated shipping and delivery of goods.
