In this activity, learners of all ages can enjoy experimenting with ice. Try this experiment at the kitchen table or in the great outdoors to encourage budding scientists to experiment with ice.

In this biology activity (page 8 of the PDF), learners will determine whether they are "tasters" or "non-tasters", test selected individuals from their families and peer group for the trait, and chart

This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.

In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

Learners are given mysterious white powders and have to determine their identity with chemical tests.

Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.

In this adapted version of poker, learners practice writing chemical formulas by playing this chemistry card game.

If you have access to a copper metal tube, this activity does a great job demonstrating what happens to matter when it's heated or cooled. This activity requires some lab equipment.

In this chemistry activity, learners explore the amount of copper in a new penny. Learners use toilet bowl cleaner to hollow out the interior of a penny with zinc inside.

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this activity, which requires adult supervision, learners get to explore the awesome power of chemistry.

This activity was designed for blind learners, but all types of learners can use it to investigate heterogeneous and homogeneous mixtures and solutions, identify the differences, and explore the conce

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.

In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

In this activity, learners make their own flip book that shows real solar flares erupting from the Sun in November 2000. Step-by-step instructions are included with photos.

In this activity, learners construct an indoors obstacle course and discover how using an eye patch can help them complete the course in the dark.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

In this activity about depth perception, learners create an optical illusion in a shoe box.

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.
