Illuminations on Rates of ReactionsAdd to list Details
In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.
What is Light?
In this four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.
Heat Speeds Up ReactionsAdd to list Details
In this activity, learners investigate the effect of heat on a reaction.
Glow Fast, Glow Slow: Alter the Rate of a Reaction!Add to list Details
Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.
Glow UpAdd to list Details
In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.
See the LightAdd to list Details
Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.
In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.
LuminescenceAdd to list Details
In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.
