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.

Traveling Networks
Source Institutions
In this geometry activity, learners explore networks painted on playgrounds, such as a four square court, and draw their own.

Keep a "SLOG" (Sleep Log)
Source Institutions
In this activity (1st on the page), learners keep a "SLOG" or Sleep Log to study their sleep patterns.

Make a Model of a Home Made From Shipping Containers
Source Institutions
In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.

Sleep Patterns
Source Institutions
In this activity about sleep rhythms (on page 21 of the PDF), learners will collect data about their own sleep cycles and use a fraction wheel to examine their data.

Three Bean Salads
Source Institutions
This game teaches ratio and proportion by having learners make "salads" that combine three types of beans in different combinations.

Special Effects: Titanic and Beyond
Source Institutions
In this activity, learners investigate how geometry plays a role in perspective.

Bridge Building
Source Institutions
This is a quick activity (on page 2 of the PDF under Hockey Sticks Activity) about how the arrangement of carbon atoms determines carbon's different properties.

2-Liter Landfill
Source Institutions
In this activity, learners gain a better understanding of how household/school waste breaks down in a landfill. Learners collect trash and then create miniature landfills in 2-liter bottles.
Musical Coathanger
Source Institutions
In this activity, learners turn an ordinary metal coat-hanger into a (very quiet) musical instrument.

Rainbow Glasses
Source Institutions
In this activity, learners explore light, color and rainbows by making their own rainbow glasses.
Build A Hydrometer
Source Institutions
In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

Conduction Countdown
Source Institutions
In this quick SciGirls activity (page 1 of the PDF under SciGirls Activity: Doghouse Design), learners will be introduced to the concept of thermal conductivity.

Crime Scene Investigation (CSI) with Powdery Mildew Fungi
Source Institutions
This exercise can be used to stimulate the investigative nature of learners as they use forensic plant pathology techniques to prove the learners' innocence in a mock murder investigation.
Piece It Together: Puzzle Hunt
Source Institutions
In this activity, learners follow clues to find five puzzle pieces, then assemble them. This activity works well with a whole group, individuals, or families.
Transparent Gelatin
Source Institutions
In this optics activity, learners explore how they can make gelatin stop light, but not stop them from seeing fruit suspended within.

Physical Change
Source Institutions
In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

Earth Walk
Source Institutions
In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook
Mystery Jars: Estimate Contents
Source Institutions
This activity puts a mathematical twist on the familiar “guessing jar.” No guesses allowed, estimates only.

Passion for Pixels
Source Institutions
In this technology activity, learners explore digital imaging and pixels. Learners "transmit" an image to a partner by creating an image on grid paper.
