Rotating Light
Source Institutions
In this activity, learners explore what happens when polarized white light passes through a sugar solution.
Luminol Test
Source Institutions
Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.
Shake It Up!
Source Institutions
Learners observe a sealed container holding a clear colorless liquid. They shake the container and the fluid turns blue. When allowed to sit for a few moments, the fluid turns colorless again.
In the Toilet
Source Institutions
This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.
What does Color have to do with Cooling?
Source Institutions
In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.
Size and Distance
Source Institutions
In this activity about depth perception, learners create an optical illusion in a shoe box.
Inverted Foucault Pendulum
Source Institutions
In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.
Acid Rain
Source Institutions
In this chemistry demonstration, acid rain is simulated in a petri dish.
Rubberband Rollback
Source Institutions
In this activity about potential and kinetic energy, learners get to roll a can across the floor and then watch it roll back to them as if by magic. This activity is always great for looks of wonder!
Big Things Come in Little Packages
Source Institutions
As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.
Circuit Bending with Play-Doh
Source Institutions
Break open that used musical toy and squish some Play-Doh over the circuit boards, and you will hear some weird and distorted sounds the manufacturer never intended!
What's Your Blood Type?
Source Institutions
In this activity, learners perform a simulated blood test procedure.
Canned Heat
Source Institutions
In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.
Heavy Metal
Source Institutions
In this activity (on pages 25-31 of PDF), learners soak sponges with different amounts of plaster of paris to simulate different levels of calcification in bone formation.
Powder Particulars
Source Institutions
In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.
Finding the Carbon in Sugar
Source Institutions
In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.
Battling for Oxygen
Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.
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.
