Best Bubbles
Source Institutions
In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.
Surface Tension Icebreaker
Source Institutions
This is a quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.
Floating Paper Clip
Source Institutions
In this activity, challenge learners to float a paper clip in a cup of water. Learners discover that a paper clip will sink in a cup of water, except when it is placed on a piece of paper towel.
Cat's Meow
Source Institutions
In this chemistry activity, learners are asked to form a hypothesis about the behavior of milk as household detergents act upon it.
Physics Over the Sink: Water Glass Magic
Source Institutions
In this simple demonstration, learners investigate the properties of air pressure. Learners place an index card on top of a glass full of water, then invert the glass.
Gravity Fail
Source Institutions
In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.
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.
Water: Clearly Unique!
Source Institutions
In this activity on page 4 of the PDF (Water in Our World), learners conduct some quick and easy tests to determine the differences between water and other liquids that look very similar to water.
Does Size Make a Difference?
Source Institutions
In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.
Penny Drop
Source Institutions
In this quick activity about the properties of water (page 1 of PDF under SciGirls Activity: Malformed Frogs), learners will use an eyedropper to slowly place one drop of water at a time onto a penny,
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.
Drops on a Penny
Source Institutions
In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.
Make a Wire Critter That Can Walk on Water
Source Institutions
In this activity, learners make water-walking critters using thin wire, and then test how many paper clips these critters can carry without sinking.
Wet Pennies
Source Institutions
Learners initially test to see how many drops of liquid (water, rubbing alcohol, and vegetable oil) can fit on a penny.
Floating Paperclip and Other Surface Tension Experiments
Source Institutions
In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.
Lotus Leaf Effect
Source Institutions
This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.
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.
Levity Through Tension: Fun with Water's Surface Tension
Source Institutions
This experiment describes how to create a "dribble bottle" which only leaks water when the cap is unscrewed. The full water bottle has a small hole made with a push pin.
