In this chemistry lab activity, learners model the colors of fireworks by burning metallic solutions in a flame and observing the different colors produced.

In this activity, learners investigate the effect of heat on a reaction.

Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.

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.

In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl

Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).
