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.
Harmful Algal Blooms: In Full Bloom
Source Institutions
In this activity, learners will investigate the impacts of harmful phytoplankton using NOAA's Coastal Services Center Harmful Algal Bloom Forecasting (HABF) Project data.
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
Multiple Reflections
Source Institutions
In this activity, learners explore how mirrors reflect light and change the way we see things.
Sink or Float?
Source Institutions
In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.
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.
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.
How Small Can You Cut?
Source Institutions
In this lesson, learners cut paper into very small pieces to explore the small size of quarks, the smallest thing we know of on Earth.
