In this activity, learners cook amino acids and sugar to explore the range of aromas released.

Learners observe a sealed container holding a clear colorless liquid. They shake the container and the fluid turns blue. When allowed to sit for a few moments, the fluid turns colorless again.

In this activity (on pages 22-24 of the PDF), learners match extreme enviroments with life forms they support.

"Exploring the Universe: Filtered Light" demonstrates how scientists can use telescopes and other tools to capture and filter different energies of light to study the universe.

In this activity, learners follow a recipe to make hollandaise sauce. Learners discover how cooks use egg yolks to blend oil and water together into a smooth mix.

In this activity, learners will create beautiful greeting cards by marbling with shaving cream and food dye. They will explore the chemistry behind the art of marbling.

This is a quick, yet dramatic activity/demonstration that introduces learners to the concept of energy transfer. A small ball is placed on top of a large ball and both are dropped together.

This is written as a display, but can easily be adapted to a hands-on activity. Learners discover how all the parts of a diaper work together to keep babies dry and comfortable.

In this activity, learners build small animated toys that move.

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon.

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

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.

In this engineering design challenge, learners build an air-powered spinning machine.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

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.
