It's a Gas!
Source Institutions
In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.
Pedal Power
Source Institutions
In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.
Disappearing Statues
Source Institutions
In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.
Paper Bridge
Source Institutions
In this engineering activity, challenge learners to construct a paper bridge that can support 100 pennies.
¡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.
Mirror Messages
Source Institutions
In this activity, learners use mirrors to write secret messages to a friend. Use this activity to explore letters, optics, and/or symmetry.
Air Lift
Source Institutions
In this physics activity, challenge learners to lift a book with just air using a plastic bag and a straw. This activity demonstrates compressed air and forces.
High Rise
Source Institutions
In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.
Secret Goldenrod Messages
Source Institutions
In this activity, learners write invisible messages on goldenrod paper, and make the message appear and disappear using acids and bases.
Paper Table
Source Institutions
In this design challenge activity, learners use tubes of newspaper to make a table that’s at least eight inches tall and strong enough to hold a heavy book!
Super Golf Tower
Source Institutions
In this engineering activity, challenge learners to build a tower out of 10 sheets of newspaper and 3 feet of masking tape, which can hold a golf ball balancing at the top.
Release the Grease!
Source Institutions
In this simple activity (on page 7 of the PDF), learners use water and liquid dish detergent to see which one removes lipstick better from an index card.
Playground Patterns of Cracks
Source Institutions
In this math activity, learners observe and sketch cracking patterns in pavement.
Flinker
Source Institutions
In this activity, learners make a foam packing peanut "flink"--neither float away nor sink--in water. Learners experiment with materials to make a Flinker that "flinks" for 10 seconds.
