This activity is designed to introduce learners to genes, genotypes and simple inheritance patterns.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this activity, learners explore how engineering has developed various means to remove impurities from water.

In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

In this activity, learners design a scientific exploration mission to a planet or moon of their choice.

In this activity, learners use simple tools to build a bookshelf with a built-in bookend.

Learners observe and compare the sizes of three toy “growing” crocodiles made from water-absorbent polymers. One is it its original state, dry, hard, and about 10cm long.

In this activity, young learners will make their own flower seed nursery in an egg carton.

In this activity, learners cut, fold, and paste paper representing biomolecules to create a three-dimensional cell membrane with embedded proteins.

Learners will follow a specific process to make their own paper using scrap paper, newspaper, or junk mail.

In this activity you'll see how the sun's tilt on its axis changes the length of shadows. For example, why is your shadow longer in winter than in summer?

In this activity, learners will measure their lung capacity by making their own spirometer. Learners will then explore factors that affect the amount of air the lungs can hold.

In this activity, learners investigate how geometry plays a role in perspective.

In this activity, learners examine photo images of Earth taken from space, and attempt to identify and explain some of our planet's geological features.

In this activity, learners will create a home for animal friends in their backyard using recycled materials. Some material suggestions include: pine straw and twigs.

In this geology activity, learners use a microscope to discover and identify the components of sand.

Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.

In this activity, learners use a fictitious map of "Tourist Town" and counters to problem solve how to place ice-cream vans on street intersections so that every other intersection is connected to one

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

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