Dye Detective
Source Institutions
    
  Learners analyze mixtures of dyes using filter paper chromatography. They place spots of the different dyes at the bottom of a piece of filter paper, and hang the paper to touch the surface of water.
  Triboluminescence
Source Institutions
    
  In this activity, learners discover what happens when they crush wintergreen-flavored candies in a very dark room.
   
Magic Inks
Source Institutions
    
  Learners write their initials by applying different clear "magic ink" solutions to separate pieces of paper and then "develop" the inks with other clear solutions.
   
Static Electricity
Source Institutions
    
  In this activity, learners will explore ways static electricity interacts with the surroundings of an object. The activity has step-by-step instructions in English and Navajo.
   
All Mixed Up!
Source Institutions
    
  In this activity, learners separate a mixture of pebbles, salt crystals, and wood pieces. They add water and pour the mixture through a strainer.
   
Flubber
Source Institutions
    
  Learners experiment with a piece of Silly Putty® by stretching, bouncing, and snapping it. They then create flubber, a similar substance, by mixing diluted glue and a solution of sodium borate.
   
Lager Lamp
Source Institutions
    
  In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.
   
Resistance is Useful
Source Institutions
    
  Learners write or draw with white crayon on white paper. They look and feel to detect their marks on the paper. Then, learners paint over their paper with watercolor paint.
   
Thar She Glows!
Source Institutions
    
  Learners observe glow-in-the-dark objects in a homemade light-proof box. Objects can include glow sticks, glow-in-the-dark toys, and toys with fluorescent paint.
   
Electric Gelatin
Source Institutions
    
  In this activity, learners explore static electricity and electrical charges while experimenting with an inflated balloon, unflavored gelatin powder, and a wool sweater.
   
Magnetic Lines of Force
Source Institutions
    
  With a magnet, iron fillings, and a bottle, you can create a cool demonstration about magnetic lines of force: the fillings will arrange themselves within the magnet's magnetic field.
   
Currently Working
Source Institutions
    
  Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.
   
See the Light
Source Institutions
    
  Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.
   
Dusted!
Source Institutions
    
  Learners press their fingertip onto a clean Plexiglas sheet. The fingerprints are then revealed as learners dust over the print with fingerprint powder.
   
Egg Drop
Source Institutions
    
  Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.
   
Make a Water Cycle Wristband
Source Institutions
    
  In this activity, learners thread colored beads onto string. Each beach represent a process of the water cycle.
   
Create Gas
Source Institutions
    
  Learners mix vinegar and baking soda together in a bottle to create a chemical reaction. The reaction produces a gas, carbon dioxide, which inflates a balloon attached to the mouth of the bottle.
   
Exploring Properties: Surface Area
Source Institutions
    
  This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.
