What's in the Water
Source Institutions
"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?
Exploring Size: Ball Sorter
Source Institutions
In this activity, learners use sieves with different-sized holes to sort balls by size.
Water Body Salinities I
Source Institutions
In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.
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
Irrigation Ideas
Source Institutions
In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.
Runaway Runoff
Source Institutions
When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.
The Ballistic Pendulum
Source Institutions
In this physics crime lab or demonstration, learners pretend they are criminologists and must find the "muzzle velocity" (speed of the bullet as it leaves the gun) of a gun used to commit a crime.
Laser Projection Microscope
Source Institutions
In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.
Exploring Products: Nano Fabrics
Source Institutions
In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.
Human Impact on Estuaries: A Terrible Spill in Grand Bay
Source Institutions
In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.
What Does Life Need to Live?
Source Institutions
In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).
Tabletop Biosphere
Source Institutions
In this activity, learners create a sealed, mini ecosystem that supplies freshwater shrimp with food, oxygen, and waste processing for at least three months.
Diffusion & Osmosis with Data Analysis
Source Institutions
This three-part lab helps learners understand the essential principles governing diffusion and osmosis.
The Watershed Connection
Source Institutions
In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.
Collect Oxygen Over Water
Source Institutions
In this activity, learners use a pneumatic trough (see related activity) to generate and collect pure oxygen.
Liquid Body Armor
Source Institutions
In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.
Instant Ice Cream with a Dry Ice Bath
Source Institutions
In this chemistry meets cooking activity, learners make carbonated, vanilla ice cream using dry ice and denatured ethanol, which are both inexpensive and accessible.
Suminagashi: Floating Ink Paper Marbling
Source Institutions
In this activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.
Exploring Earth: Land Cover
Source Institutions
This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.
Sublimation Bubbles
Source Institutions
"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.
