This activity (on page 2 of the PDF) features a recipe to create the stretchy polymer Flubber from Borax detergent, white glue, and water.

In this demonstration, learners observe how liquid nitrogen both boils and freezes ingredients to make ice cream in two minutes.

In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.

In this outdoor, freshwater activity, learners explore the behavior and food preferences of crawdads (or crabs) by "fishing" for them with various baits.

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

Learners place an M&M candy in water and observe what happens. The sugar-and-color coating dissolves and spreads out in a circular pattern around the M&M.

This online interactive has three activities in the NanoLab (press the upper right button): Build, Zoom, and Transform.

In this activity on page 5 of the PDF, learners mimic the process for making bricks. Learners shape and bake creations from a dough that is made from flour, salt, and water.

In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.

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

In this activity, learners construct a rocket powered by the pressure generated from an effervescing antacid tablet reacting with water, and build a launch pad for their rocket.

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?
