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 two separate bags, learners mix water with Epsom salts and detergent.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

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 explore the engineering behind life vests or personal flotation devices and the challenges met by these devices.

This lesson focuses on how materials behave differently as their surface area increases.

In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area.

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.
