Personal Pinhole Theater
Source Institutions
Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

Paper Proteins
Source Institutions
In this activity, learners use an origami template to design eight amino acids. Learners configure the amino acids to form a protein. Use this activity to introduce proteins and amino acids.
Pour Some: Measure Serving Size
Source Institutions
Make snack time into measuring time and learn to read Nutrition Facts labels. Try this when you’re using “pourable” foods, such as cereal, yoghurt, or juice.

Circles or Ovals?
Source Institutions
This science activity demonstrates the dominant eye phenomena. What does your brain do when it sees two images that conflict?

Tomb Mapping
Source Institutions
In this activity, learners examine the culture and history of the tomb site.

Pollution Patrol
Source Institutions
In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

Make Your Own DNA
Source Institutions
Learners match puzzle pieces to outlines of a DNA strand. The puzzle pieces represent the four chemicals making up DNA base pairs: adenine, thymine, guanine, and cytosine.

Heart of the Matter
Source Institutions
In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

The Carbon Cycle Game
Source Institutions
In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

Make a Shaker
Source Institutions
This hands-on activity shows you how to make a shaker -- a small instrument with a big sound! Fill it with beads or even pennies for a cool sound.

Smooth Operator
Source Institutions
In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.

Thrush Songs: An Interactive Game
Source Institutions
In this interactive game, learners listen to the songs of four different thrushes and then try to match each bird with its song.

Control a Bird’s Flight
Source Institutions
In this engineering design challenge, learners make a bird and then control its flight with attached strings.

Busted by Biology
Source Institutions
In this two-part activity, learners will extract their own DNA from their cheek cells and learn how DNA is analyzed and used to solve crimes.

Carbon Cycle Poster
Source Institutions
In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

Tube Zither
Source Institutions
In this activity, learners explore sound by constructing tube zithers, stringed instruments from Southeast Asia and the South Pacific.

Oil Spill Solutions
Source Institutions
In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

Make Money Appear Before Your Eyes
Source Institutions
In this optics activity, learners use water to make a coin "appear" and "disappear." Use this activity to demonstrate how light refracts and introduce light as waves.

Paper Chromatography with Leaves
Source Institutions
In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.

Screaming String Thing
Source Institutions
In this simple and fun activity, learners discover the relationship between vibration and sound by making a squeaky toy instrument out of simple household materials.
