Dripping Wet or Dry as a Bone?
Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.
Perspectives: Powers of 10
Source Institutions
In this activity, learners complete a series of drawing activities to explore scale and powers of 10. Learners first trace each other on 1-meter-square pieces of paper.
Public Key Encryption: Kid Krypto
Source Institutions
In this activity, learners conduct a simulation exercise related to public key encryption and try to intercept a message sent between two learners.
Battleships: Searching Algorithms
Source Institutions
This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.
A Place in Space
Source Institutions
Learners construct and use a "real" 3D coordinate system out of balsa wood and foam core. They will then be able to locate coordinates in space.
Twenty Guesses: Information Theory
Source Institutions
This activity introduces the idea that computer scientists measure information by how "surprising" a message is.
Launch It
Add to list DetailsIn this design challenge activity, learners use a balloon and other simple materials to design an air-powered rocket that can hit a distant target.
Gumdrop Dome
Source Institutions
In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.
Radioactive Decay of Candium
Source Institutions
In this simulation, learners use M&M™ candy to explore radioactive isotope decay.
Dunking the Planets
Source Institutions
In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.
Mega Bounce
Source Institutions
In this outdoor activity (on page 2 of the PDF under GPS: Baseball Activity), learners will investigate the transfer of energy using sports equipment.
Super Bounce
Source Institutions
In this activity (on page 1 of the PDF under SciGirls Activity: Soccer Ball Kick), learners will investigate the transfer of energy using sports equipment.
Bouncing Balloons
Source Institutions
In this sports-themed engineering activity, learners create super bouncy balls out of balloons. Learners brainstorm, test their designs, and share results.
Exploring Strange New Worlds
Source Institutions
This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.
Four Corners
Source Institutions
In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.
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.
Paint by the Numbers
Source Institutions
In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.
The Poor Cartographer: Graph Coloring
Source Institutions
In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.
Divide and Conquer: Santa's Dirty Socks
Source Institutions
This activity introduces the idea of "divide and conquer" using a fictitious but serious problem--a pair of dirty socks has accidentally been wrapped in one of the presents that Santa is about to deli
Roving on the Moon
Add to list DetailsIn this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.
