Clean Water: Is It Drinkable?
Source Institutions
In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

Crank It Up
Source Institutions
In this engineering activity, learners explore simple machines and then build cardboard automata using cams.

Exploring a Complex Space-Filling Shape
Source Institutions
In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.

Scaling an Atom
Source Institutions
In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!

Design Your Own Rube Goldberg Machine
Source Institutions
Engineer and cartoonist Rube Goldberg is famous for his crazy machines that accomplish everyday tasks in overly complicated ways.

Shell Shifts
Source Institutions
Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.

Soaring Satellites
Source Institutions
Working in small teams, learners try to build a satellite that can float for at least five seconds in the marked area of a vertical wind tube.

Plant Tissue Culture: Classroom Activities in Plant Biotechnology
Source Institutions
In this activity related to plant biotechnology, learners use the tissue culture process to rapidly produce clones (genetic copies) of a particular plant (cauliflower, rose cuttings, African violet le

Kinematic Fanatic
Source Institutions
In this activity, learners are challenged to design and build a system of gears and kinematics to create a hand-stamping machine.

Gel Electrophoresis
Source Institutions
In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

Set It Straight
Source Institutions
In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads.

What Gives?
Source Institutions
In this activity, learners design, build and test a model suspension bridge for sturdiness and strength.

Make a Totem Pole
Source Institutions
In this activity (on page 2 of PDF), learners make their own totem poles out of recycled materials.

Balloon Car
Source Institutions
In this physics activity, challenge learners to make and race a balloon-powered car. Learners construct the body out of a paper cup, wheels out of wooden spools. and fuel tank out of a balloon.
Starburst® Graph
Source Institutions
In this activity, learners use Starburst® candy to sort, classify, compare, and graph. Learners grab a handful of one-inch candy squares, sort them by color, graph the candy, and discuss the results.

Color Sudoku
Source Institutions
The popular sudoku puzzles use numbers, but the game could played with any set of 9 different objects!

Pencil Balance
Source Institutions
In this activity, challenge learners to make a pencil stand on its tip using only two pieces of wire and two clothespins. Use this activity to demonstrate the center of gravity.

DIY Pasta Rover
Source Institutions
In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

Geometry and Algebra: The Future Flight Equation
Source Institutions
In this activity, learners discover how NASA engineers develop experimental aircraft.

Does Sunscreen Protect My DNA?
Source Institutions
In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.
