Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.

In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

In this activity, learners explore the behavior of cold-blooded animals. Learners discover what happens when they change a fly's temperature.

In this activity, learners will test the strength of different brands of paper towels.

In this activity, learners will create a drawing with dry erase markers and watch it come to life. Learners will explore chemistry, art and storytelling through this activity.

In this activity, learners will make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.

In this activity, children and adults work together to explore their relationship with technology and examine ways to make sustainable media consumption choices.

In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this activity, learners will explore how and why weight distribution works.

In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.

This is a guide for facilitating interaction at a touch tank with marine animals. The instructions are for setting up a display in an informal science center, but could work anywhere.

In this activity, learners will build a bee hotel for pollinators. Learners will explore building and ecology through this activity.

In this activity, learners will repurpose an old t-shirt to create their own yarn or string.

In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.
