In this chemistry activity, learners will separate a mixture of FD&C dyes (colors certified and allowed by the US for the Food, Pharmaceutical, Cosmetics & Personal Care industry) to practice

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

In this life science activity (page 8 of the PDF), learners explore the carbon cycle by mixing yeast, sugar and water.

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 shrink the scale of the vast solar system to the size of their neighborhood.

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.

In this physics activity, learners attempt to lift a jar full of rice using only a spoon.

In this activity, learners use three types of cheesy snacks--cheese balls, cheese puffs, and Cheetos--to learn about polymers.

Make your own mummy! Using a combination of salts, transform an apple into a mummy and discover how the Ancient Egyptians used drying as one step in the mummification process.

In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.

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

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

In this activity, learners will discover why there are holes in bread.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity (on page 2 of the PDF), learners make a plastic protein polymer from milk. Adding vinegar to milk causes the protein casein to solidify or curdle.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

Learners explore capillary action in plants (such as plants ability to move water from roots to leaves) in an investigation called Paper Blooms.

In this activity, learners mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow.
