Exploring Forces: Gravity
Source Institutions
In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

Chromatography Observations
Source Institutions
In this activity, learners will explore how water affects marker on filter paper. Learners will use science process skills such as making observations and predictions as they explore color.

The Liquid Rainbow
Source Institutions
Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

Wonderful Weather
Source Institutions
In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

Radial Chromatography
Source Institutions
How many colors make black? Gather as many water soluble black markers as you can find.

Tissue Paper Spray Art
Source Institutions
In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.

Exploring Science Practices: Early Explorations
Source Institutions
This activity gives caregivers and their children an opportunity to practice scientific ways of thinking that are developmentally appropriate for early learners.

Exploring Earth: Paper Mountains
Source Institutions
In this activity, learners explore in what ways the shape of the land and the pull of gravity influence how water moves over Earth.

Static Water
Source Institutions
In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

Boats Afloat
Source Institutions
In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

Be A Pasta Food Scientist
Source Institutions
In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

Homegrown Xylophone
Source Institutions
In this activity, learners create music from a series of bottles filed with water. Learners discover that the sound produced by each bottle depends on the amount of water in the bottle.

Mixing and Unmixing in the Kitchen
Source Institutions
In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

Mystery Sand
Source Institutions
In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

Vortex
Source Institutions
In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

Cartesian Diver
Source Institutions
In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

Energetic Water
Source Institutions
In this activity, learners explore how hot and cold water move. Learners observe that temperature and density affect how liquids rise and fall.

M&M's in Different Temperatures
Source Institutions
Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

Which Powder is It?
Source Institutions
In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.

Plant Power
Source Institutions
In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.
