Make snack time into measuring time and learn to read Nutrition Facts labels. Try this when you’re using “pourable” foods, such as cereal, yoghurt, or juice.

In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.

It's difficult to see convection currents in any liquid that's undergoing a temperature change, but in this Exploratorium Science Snack, you can see the currents with the help of food coloring.

In the kitchen, learners can perform their own density investigation.

In this hands-on activity, learners explore static electricity through the use of common household products. They also explore the connection between static electricity and cold weather.

In this activity, learners thread gumdrops together to make a model of a polymer.

In this physics activity, learners will investigate the strength of egg shells.

In this activity, learners make their own rock candy. Crystals will grow from a piece of string hanging in a cup of sugar water. The edible crystals may take up to a week to form.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

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.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

In this activity, learners use marshmallows and gum drops to construct seven models of molecules. Learners classify (solid, liquid or gas) and draw diagrams of the molecules.

Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

Learners see that a carrot slice sinks in fresh water and floats in saltwater.

In this quick activity (page 1 of the PDF under SciGirls Activity: California Fish), learners will build a simple Cartesian Diver in an empty 2-liter bottle.

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.
