The Carbon Cycle: Carbon Tracker
Source Institutions
In this activity, learners play NOAA's Carbon Tracker game and discover ways to keep track of carbon dioxide and other greenhouse gases in the world.
The Checks Lab
Source Institutions
A group of learners has an envelope containing a series of bank checks. A few checks are removed at a time, and the team attempts to construct a plausible scenario which involves those checks.
Headphone Helper
Source Institutions
In this design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.
Crushing Test
Source Institutions
In this activity, learners design a crushing test and discover that identifying and controlling the variables may be difficult.
Cookie Surface Area
Source Institutions
This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.
Oil Spill Cleanup
This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.
Exploring Bouncing Balls
Source Institutions
Learners explore the physical properties of a variety of balls and how they bounce.
As the Rotor Turns: Wind Power and You
Source Institutions
In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from
Mars from Above: Viewing Volcanoes
Source Institutions
In this activity, learners create volcanoes like those they have examined on Earth and Mars through images taken by spacecraft.
M&M's in Different Sugar Solutions
Source Institutions
In this activity, learners investigate whether having sugar already dissolved in water affects the speed of dissolving and the movement of sugar and color through the water.
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
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.
Multiple Reflections
Source Institutions
In this activity, learners explore how mirrors reflect light and change the way we see things.
Space Stations: Measure Up!
Source Institutions
In this activity, learners work in pairs to measure each other's ankles with lengths of string.
The Colors of Flowers
Source Institutions
In this activity, learners perform an experiment to find out what determines a flower's color.
Head in the Clouds
Source Institutions
In this activity, learners create a CloudSpotter wheel and record the different types of clouds they observe twice daily over several days.
Tug-of-War
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Tug O' War) is a full inquiry investigation into tug-of-war physics. Groups of learners will test two tug-of-war strategies.
Does the Moon Rotate?
Source Institutions
This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.
Print Hints
Source Institutions
In this physical sciences activity, learners explore how forensic investigators collect prints from a crime scene. Learners make hand impressions in damp sand and analyze the patterns they observe.
Airboat
Source Institutions
In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.
