In this activity, learners discover that two pendulums suspended from a common support will swing back and forth in intriguing patterns, if the support allows the motion of one pendulum to influence t

In this activity about living things and gravity (page 5 of PDF), learners design and build an exoskeleton or an endoskeleton for an animal of their own invention.

In this activity, learners work in pairs to conduct a series of experiments using a balloon, drinking straw, and paper.

In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.

In this activity (page 2 of pdf), learners craft a model of a skate egg case and come to understand that cartilaginous fish such as sharks and shakes employ reproductive strategies that differ from th

Wheels aren't the only things that can "roll" objects that are placed on top of it. Make non-intuitive shapes from cutouts and a compass to demonstrate this.

This activity (located on page 3 of the PDF) is a full inquiry investigation into mapping the underground “plumbing” of geysers.

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

What's a more compelling problem to solve than being stranded on a deserted island?

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 classic memory game (on pages 37-45 of PDF), learners turn over tiles to reveal images on the back.

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

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

In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

“Exploring the Universe: Orbiting Objects” is a hands-on activity that invites visitors to experiment with different sized and weighted balls on a stretchy fabric gravity well.

In this activity about light and perception, learners discover how a flash of light can create a lingering image called an "afterimage" on the retina of the eye.

This fun hands-on astronomy activity lets learners explore models of the Milky Way and other galaxies to get a sense of relative distances to other galaxies.

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.
