In this activity, learners create a marble maze that contains sensors. As a metal marble triggers the sensors, the Pico Cricket turns on lights or spins motors.

In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.

This outdoor activity (on page 2 of the PDF under SciGirls Activity: Sand Dunes) is a full inquiry investigation into how the amount of moisture in a sand dune relates to the number of plants growing

Learners explore how the attractive forces between water molecules create surface tension and allow certain objects to float on the surface of water.

Make your own mummy! Using a combination of salts, transform an apple into a mummy and discover how the Ancient Egyptians used drying as one step in the mummification process.

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.

This activity (on page 3 of the PDF under GPS: Roller Coaster Design Activity) is a full inquiry investigation into g-force and acceleration.

Build a musical ice theremin by programming a micro controller, like a Pico Cricket to respond to resistance generated by the ice melting, or the ice being touched.

In this activity, learners explore light, color and rainbows by making their own rainbow glasses.

In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).

In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection

In this activity, learners make a black box device that serves as an excellent analogy to Rutherford's famous experiment in which he deduced the existence of the atomic nucleus.

In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.

In this chemistry demonstration, acid rain is simulated in a petri dish.

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

In this activity, learners discover that it's difficult to distinguish between two different shades of gray when they aren't separated by a boundary.

In this activity, learners make acid/base indicator paper, place the indicator paper on an anthill, disturb a bunch of ants, and then observe what happens!
