In this activity (on page 2 of the PDF), learners explore surface tension by adding pennies to cups which are "full" of plain water or soapy water.

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

In this activity (on page 2 of the PDF), the learner places a golf ball between salt water and colored fresh water. The golf ball is not as dense as the saltwater.

Learners use filter paper and water to analyze six different markers. They mark the paper with ink, and dip the paper in water. The water travels up the paper and dissolved ink travels with it.

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.

Learners observe a sealed test tube containing a small amount of solid stearic acid.

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

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.

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 chemistry demonstration, learners will discover that phenolphthalein is an acid/base indicator. One learner will read a poem about four witches making a potion.

This is written as a display, but can easily be adapted to a hands-on activity. Learners observe and shake containers of shiny liquids.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.
