In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

In this activity, learners explore how ordinary marshmallows expand when heated in a microwave.

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 explore the density of an object in water. Learners will compare what happens to fruits and vegetables in regular and salt water.

In this activity, learners make their own edible DNA double helix out of candy and find out about the shape of DNA.

Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.

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.

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 activity, learners touch supercooled water drops with an ice crystal and trigger the water drops to freeze instantly.

Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.

In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

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

In this activity on page 6 of the PDF (Chemistry—It’s Elemental), learners explore some of the properties of copper using a few common household ingredients.

This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

In this activity, learners make a model of the solid Earth's layers that's good enough to eat! Learners use tasty foodstuffs to simulate Earth's inner core, outer core, mantle, and crust.

In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.

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

Using a milk-based recipe, learners create "moo glue" which is basically white school-type glue. The "secret ingredient" in milk that helps make glue is a chemical called casein.
