Storm Water Runoff Pollution
Source Institutions
This activity (located on page 8 of the PDF) introduces learners to the concept of Non-point Source Pollution--what happens when rain washes garbage and other pollutants into rivers and lakes.
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.
Good Catch!
Source Institutions
In this activity, learners "go fishing," then practice ruler use and size/pattern comparison with the animals they catch.
Evolution as Reproduction with Variability
Source Institutions
In this online activity, learners discover how random variation influences biological evolution.
Heavy Air
Source Institutions
In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.
How it is Currently Done
Source Institutions
In this quick activity, learners observe how wind creates ocean currents.
Constellation Tubes
Source Institutions
In this activity, learners will create their very own constellation.
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.
Make Your Own Sea Otter
Source Institutions
In this activity about sea otters, learners make their own "otter whiskers" and use them to find objects underwater.
Polar Opposites
Source Institutions
In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.
Water Bugs
Source Institutions
Some bugs can walk on the surface of a lake, stream, river, pond or ocean.
What am I?
Source Institutions
In this activity, learners examine nanoscale structures of common things.
Fill 'er Up!
Source Institutions
Learners discover that their breath contains carbon dioxide, one of the pollutants found in car exhaust.
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.
North American Endangered Amphibians Card Game
Source Institutions
In this activity, learners can play two card games related to endangered species, specifically North American amphibians.
Place Matters: How Sound Changes Due to Environment
Source Institutions
This is an online simulation of how sound changes due to environment. How does place--like a cave, a pier, or a forest--affect certain sounds?
Air Pressure
Source Institutions
In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.
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?
Why is the Sky Purple?
Source Institutions
This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.
Convection
Source Institutions
In this activity, learners model atmospheric convection currents using food coloring, water, and clear cups. Activity includes step-by-step instructions, STEM connections, and more.
