The Carbon Cycle: How It Works
Source Institutions
In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another
Design a Safer Bicycle Helmet
Source Institutions
In this activity, learners design a bicycle helmet. Participants will explore the design of bicycle helmets to gain an appreciation for the role that helmet layers play protecting the head.
Particle Detection
Source Institutions
By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.
Soaring Satellites
Source Institutions
Using a vertical wind tube and using simple materials, individuals and groups attempt to design a "satellite" that floats for at least 5 seconds.
Quipus
Source Institutions
Learners create an Incan counting device called a quipu (pronounced kee-poo).
Homemade Rube Goldberg Machine
Source Institutions
In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.
Sink or Swim?
Source Institutions
In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.
Making An Impact!
Source Institutions
In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.
Cup Draw
Source Institutions
In this activity, learners construct drawing machines using a cup, some markers, and a cricket to control the movement. A programmed LEGO RCX or Cricket is required for this high-tech version.
Secret Writing Devices
Source Institutions
In this activity about encryption, learners cut out a secret decoder badge from a handout and use it to encode messages to each other.
Ocean in a Bottle
Source Institutions
In this activity, learners consider how oil spills behave in the ocean and what impact they have on marine wildlife.
Can Nutrients in Water Cause Harm?
Source Institutions
In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.
Lungometer
Source Institutions
In this environmental health activity, learners investigate their own vital lung capacities.
How Sweet It Is
Source Institutions
In this activity (4th activity on the page), learners use their sense of smell to rate and arrange containers filled with different dilutions of a scent (like cologne or fruit juice) in order from wea
Survival of the Fittest: Variations in the Clam Species Clamys sweetus
Source Institutions
This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi
Survival of the Fittest: Battling Beetles
Source Institutions
This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.
Trees: Recorders of Climate Change
Source Institutions
In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho
Environmental Chemistry
Source Institutions
In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.
Wind Turbine Blade Design
Source Institutions
In this activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.
Tracking Otters
Source Institutions
This activity (on pages 38-43) has learners simulate the way scientists track and map the movement of otters in the wild using radio trackers.
