Exploring Products: Nano Sand
Source Institutions
In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.
Salt 'n Lighter
Source Institutions
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.
Chromatography
Source Institutions
In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion.
Surface Tension
Source Institutions
In this activity exploring liquid dynamics, learners design and build a clay channel in a tray of water and then see what happens when food coloring and liquid soap are added to the mix.
Pepper Scatter
Source Institutions
In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.
To Dye For
Source Institutions
Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.
Miscibility
Source Institutions
Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.
Pepper Scatter
Source Institutions
In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract
That Sinking Feeling
Source Institutions
In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.
Exploring Products: Nano Fabrics
Source Institutions
In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.
Make Your Own Deep-Sea Vent
Source Institutions
In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.
Shrinking Cups
Source Institutions
This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.
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.
Water Ways
Source Institutions
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.
Fireworks in a Glass
Source Institutions
In this activity, learners use water, oil, and food coloring to observe a chemical reaction that creates a shower of colors inside of a glass.
