In this collection of demonstrations, learners explore Newton's Laws of Motion.

In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.

In this activity, learners explore how the hull shape impacts a ship's performance and stability.

In this activity, learners build inexpensive pulley assemblies from pulley wheels used for sliding screen door replacement or from clothesline spreaders.

In this activity, learners explore sublimation by conducting experiments with dry ice.

In this activity, learners explore how wind energy can be generated on both a large and small scale.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this activity, learners will design a protective package for an egg that will allow the egg to withstand a fall without cracking.

In this activity, learners use cardboard bases and track tubes to make a ball run to explore the properties of mass, force, and motion.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

In this activity, learners build a nanorover model using styrofoam meat trays and a balloon.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

Learners work with plastic sheeting, masking tape, and string to design the perfect material for plastic chair webbing, and then construct their webbing.

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

In this activity, PVC pipe, plastic water bottles and vinyl tubing are used to make a simple working toilet model. The model shows the role of a siphon in the flushing of a toilet.

In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.

In this activity, learners discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.

In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.
