Malformed Frogs
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Malformed Frogs) is a full inquiry investigation into using indicator species to assess the health of an environment.
Oil Spill Cleanup
This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.
Rainbow Film
Source Institutions
In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.
LEGO Robots
Source Institutions
This activity (on page 2 of the PDF under GEMS Activity) is a full inquiry investigation into technology design and testing.
Built in Stopwatch
Source Institutions
In this activity (3rd on the page), learners investigate circadian rhythms by examining how well people do with estimating time.
Average Names
Source Institutions
In this activity, learners compare the number of letters in the names of the people in their families or group of friends.
Cylindrical Wing
Source Institutions
In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.
The Shadow Knows I
Source Institutions
In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.
Drawing Conclusions
Source Institutions
In this weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.
Mammal Flipbooks
Source Institutions
In this activity, learners explore mammal locomotion by constructing flipbooks.
Signs of Change: Studying Tree Rings
Source Institutions
In this very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible
Big Bubbles
Source Institutions
How do you measure a bubble when it's floating? You can't really, but in this activity, learners can measure the diameter of the ring of suds a bubble leaves on a flat surface.
Games of Chance and Brains
Source Institutions
In this activity, learners build and play three math games. In the first game, called "Switcheroo," learners place marbles in holes 1 through 4 and 7 through 10.
Medical Mystery
Source Institutions
This activity (on pages 15-23) combines interactive role-playing and graphing to introduce learners to the health affects of pollen.
Estimation
Source Institutions
In this online activity, learners will explore size estimation in one, two and three dimensions. Multiple levels of difficulty allow for progressive skill improvement.
Honeycomb Geometry
Source Institutions
In this activity, learners will build a honeycomb. Learners will investigate how the shape of the honeycomb develops. Activity includes step-by-step instructions and extension ideas.
Space Stations: Measure Up!
Source Institutions
In this activity, learners work in pairs to measure each other's ankles with lengths of string.
Make a Human Scale Ladder
Source Institutions
In this quick activity about size and scale (on page 2 of the PDF under What's Nano?
Radar Mapping: What's in the Box?
Source Institutions
In this activity, learners mimic remote sensing. Learners use a stick to measure the distance to a "planet surface" they cannot see, and create their own map of the landscape.
Light and Sound
Source Institutions
In this four-part activity, learners explore light and sound through a variety of hands-on investigations.
