In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

In this activity, learners design a device to solve a problem: how to get a ball out of a drain pipe.

In this activity (located at the bottom of the page), learners investigate soil and explore the creatures that live in it.

In this activity, learners construct a device that allows them to look over ledges or around corners.

In this physics activity, learners will explore buoyancy.

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, learners will put a set of containers in order by capacity. Would the tallest container hold more or less water than the wide, short one?

In this outdoor game, learners role play predator and prey to explore the importance of keen hearing and silent stalking skills in the animal world.

In this quick activity, learners observe how wind creates ocean currents.

In this challenge, learners have to figure out in what order to combine five solutions to change the color from clear, to yellow, to blue, and back to clear.

In this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving.

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

In this experiment, learners examine the way oil affects bird feathers and test different cleanup methods to find out which works best.

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

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In this activity, learners will develop a method to test five similar-looking powders (baking soda, baking powder, cream of tartar, detergent, and cornstarch) with four test liquids (water, vinegar, i

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.
