Exploring Earth: Investigating Clouds
Source Institutions
“Exploring Earth: Investigating Clouds” is a hands-on activity in which visitors create a cloud in a bottle and explore it with laser light.
Water Wire: Electricity Flowing Through Water
Source Institutions
In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.
Desert Water Keepers
Source Institutions
In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.
Float My Boat
Source Institutions
In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?
In the Toilet
Source Institutions
This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.
Gravity Fountains
Source Institutions
This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.
What's So Special about Water: Absorption
Source Institutions
In this activity about water's cohesive and adhesive properties and why water molecules are attracted to each other, learners test if objects repel or absorb water.
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.
Foam Tower
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Water Slides), learners will whip up some suds with a cup of water and a tablespoon of dish soap until the bubbles are stiff enough to star
What Molecules Make the Holes in Bread?
Source Institutions
In this activity, learners will discover why there are holes in bread.
Ice Cube Painting
Source Institutions
In this activity, learners "draw" with frozen tempera paint. The ice cubes are prepared the day before by placing watered down tempera paint and popsicle sticks in ice cube trays.
Under Pressure
Source Institutions
In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.
Float or Sink?
Source Institutions
In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.
Convection Current
Source Institutions
In this activity, learners make their own heat waves in an aquarium.
The Water (Hydrologic) Cycle: Transpiration
Source Institutions
In this lab, learners grow broad bean (also called fava bean) plants in three EarthBoxes for a few weeks before exposing one to wind (using a fan), another to heat (using a lamp), and the third to not
Using Solar Energy
Source Institutions
In this activity, learners discover how solar energy can be used to heat water.
Water Underground
Source Institutions
Many people get water from a source deep underground, called groundwater.
Go With the Flow
Source Institutions
In this activity, learners will observe laminar and turbulent flow of water using only a plastic bottle, liquid hand soap, food coloring and water.
How Does Water Climb a Tree?
Source Institutions
In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.
Water Drop Races
Source Institutions
In this activity, learners will explore the physics of liquids and gas by playing with both! Learners of any age use their own breath to move drops of water across a smooth wax paper surface.
