In this physics activity, learners experiment with the attractive and repulsive power of magnets.

Learners classify a variety of objects by their characteristics. They then design an experiment to determine which objects float or sink in water and add this characteristic to their classification.

In this activity, learners design a device to solve a problem: how to get a ball out of a drain pipe.

In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

This is written as a display, but can easily be adapted to a hands-on activity. Learners observe and shake containers of shiny liquids.

Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

This is an activity (on page 2 of the PDF under Bone Regrowth Activity) about the two main components of bone - collagen and minerals (like calcium) - and how they each contribute to its flexibility a

In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.

In this math lesson, learners compare products to determine the best product.

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