Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

This Exploratorium activity can be used in many contexts because geysers are great opportunities for learning about heat and temperature changes as well as geological/space science phenomena.

In this chemistry activity, learners witness an exothermic reaction, while making their very own, completely usable sidewalk chalk. This is also an excellent activity for exploring color mixing.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

In this activity (on pages 13-16 of the PDF) learners investigate three mystery samples to see which one contains life. The three samples are sand, sand and yeast, and sand and antacid.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

In this group activity, learners consider environmental conditions—temperature, presence of water, atmosphere, sunlight, and chemical composition—on planets and moons in our solar system to determine
