Waves: An Alternative Energy Source
Source Institutions
In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

Star Power
Source Institutions
In this activity, learners create a star show and discover how they can prevent light pollution. Using simple materials, learners first design constellation boxes.

Paperfolding Polyhedrons
Source Institutions
In this activity (on pages 55-66 of PDF), learners fold paper into origami shapes and then combine several identical shapes into a three-dimensional structure.

Resonant Rings
Source Institutions
Things that are different sizes and stiffness vibrate differently, and in this Exploratorium Science Snack, you'll see how rings of various diameters react to vibration and external forces.

Cipher Wheel
Source Institutions
In this activity, learners make their own encrypted code to pass along secret messages using a printable cipher wheel.

Building with Wonderful Junk
Source Institutions
In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

AM in the PM
Source Institutions
In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.

Measure the Pressure II: The "Dry" Barometer
Source Institutions
In this activity, learners use simple items to construct a device for indicating air pressure changes.

Shadow Puppets
Source Institutions
In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.

Airplane Wing Investigation
Source Institutions
This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

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

Bone Basics
Source Institutions
This is an activity (on page 2 of the PDF under Bone Regrowth Activity) about the two main components of bone - collagen and minerals (like calcium) - and how they each contribute to its flexibility a
Magic Turtle Squares
Source Institutions
In this math activity, learners create a magic turtle where all the rows, columns and diagonals add up to fifteen.

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.

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

Cleaning Air with Balloons
Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

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.
Movin' and Groovin'
Source Institutions
In this math activity, learners play a game and identify patterns with fun moves and sounds. Discover how dancing and signing involve patterns.

Gross Growth
Source Institutions
In this activity, learners grow germs collected from their hands and other objects. They cultivate the germs on a growth medium (such as slices of grapefruit or processed cheese) for a week.

Smell Match
Source Institutions
In this matching activity (3rd activity on the page), learners use their sense of smell to match pairs of opaque containers filled with various smelly items like orange peel, roses, or moth balls.
