Old Faithful Plumbing Investigation
Source Institutions
This activity (located on page 3 of the PDF) is a full inquiry investigation into mapping the underground “plumbing” of geysers.

Paper Airplane Contest
Source Institutions
In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.

Race to the Top
Source Institutions
In this math game (Page 6 of the Are You Game? PDF), learners examine the probability of rolling sums from 0 to 12 with two dice. The first player to reach the finish line is the winner.

Paper Bridge
Source Institutions
In this engineering activity, challenge learners to construct a paper bridge that can support 100 pennies.

¡Libera el globo!
Source Institutions
En esta actividad, los aprendices usarán la lógica para ganar un juego. Dos personas toman turnos quitando uno o dos "cuerdas" de las estacas en el suelo.

Motor Effect
Source Institutions
See what force a magnet has on a wire that has current running through it: will it push it, pull it, or will nothing happen? This is the foundation of a simple electric motor.

Cooling the Mummy's Tomb
Source Institutions
In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.

From Gas to Liquid to Solid
Source Institutions
What causes frost to form on the outside of a cold container? In this activity, learners discover that liquid water can change states and freeze to become ice.

¡Espirales de Colores!
Source Institutions
En esta actividad sobre la densidad de los líquidos, los participantes ven si las gotas de colorante se hunden en diferentes soluciones de agua.

Persistence of Vision
Source Institutions
If you had a long tube with a 5 millimeter wide slit, would you see the entire Golden Gate Bridge?
Numbered Heads
Source Institutions
In this math activity, learners play a game and use a variety of strategies to solve a hidden number problem (or missing factor). Learners practice their number and operations skills.

Colour by Numbers: Image Representation
Source Institutions
This activity shows learners how computers use numbers to represent pictures. A grid is used to represent the pixels (short for picture elements) of a computer screen.

A Stand-up Egg
Source Institutions
In this science trick, learners get an egg to stand-up on its long-axis vertical to a table's top.
Six Squares: Geometry and Design
Source Institutions
In this activity, learners take a turn contributing a closed figure made of six squares to a large grid; each must be different from all the others on the grid so far.

Glider
Source Institutions
In this activity, learners construct paper airplanes that twist and turn.

Balancing Ball: Suspend a ball in a stream of air
Source Institutions
Balance a ball in the air with a hair dryer! This Exploratorium produced activity shows learners concepts like lift and air streams. You can try many different angles, speeds, and ball types.

Gravity-Defying Water
Source Institutions
In this activity, learners explore gravity and air pressure as they experiment with holding a glass full of water upside down, without spilling it, using a simple piece of cardstock.

Straws and Airplanes
Source Institutions
Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.

Lateral Inhibition
Source Institutions
Which one of your eyes are dominant? Do they act independently or are they equally "in control?" This activity explores how your eyes work (or don't work) together.

Solar Flip Book
Source Institutions
In this activity, learners make a flip book that shows the progression of two solar events on reversible sides of the flip book.
