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

In this yummy chemistry activity which requires adult supervision, learners use sugar and water to explore how crystals form.

In this simple activity (on page 2 of the PDF), learners make a crystal garden using salt, water, and a brick.

In this hands-on botany activity, learners sprout vegetables in film canisters.

Don't scream for ice cream -- make it with milk, sugar, flavoring and some 'salt-water' ice. Discover the chemistry of ice cream by creating your own.

In this activity, learners will "paint" their own crystal artwork by creating a picture with a super saturated salt solution.

In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.

Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.

Learners observe and record what happens when they manipulate bottles containing a liquid (water or corn syrup) and one or more objects (screw, nail, paper clip).

This activity (on page 2 of the PDF) features a recipe to create the stretchy polymer Flubber from Borax detergent, white glue, and water.

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

This is written as a display, but can easily be adapted to a hands-on activity. Learners discover how all the parts of a diaper work together to keep babies dry and comfortable.

In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.

In this physics activity, learners will explore buoyancy.

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.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.
