In this activity, learners are challenged to design, build and test a birdhouse that will stay cool in the sun.

In this activity, learners use Styrofoam to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.

In this activity, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.

In this activity, learners will use magnets and household items to create a structure that allows paperclips to appear like they are floating.

Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.

In this activity, learners build their your own seismograph with household materials to document shaking.

Testing magnets is always a fun pastime, but here, we're going beyond "will it attract the magnet?" In this activity, learners will investigate which materials allow magnetic fields to pass through or

Learners attach an egg to a rubber-band bungee cord and drop the egg.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity, learners use marshmallows and gum drops to construct seven models of molecules. Learners classify (solid, liquid or gas) and draw diagrams of the molecules.

We're told from a young age that we have 5 senses, but we have many more. One of which is our awareness of our own body part's orientation and position.

In this quick activity, Dracula has a hole in his house and learners help solve the problem by using a mirror and protractor to reflect incoming light out of his house.
