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.

This activity (on page 2) explores how sensing is part of robotics. Learners try tying their shoes with different constraints.

In this chemistry activity, learners fill two test tubes with a solution of "artificial stomach fluid," consisting of hydrochloric acid in the same concentration as in human stomachs, some soap to cre

Learners use a mortar and pestle to extract clove oil from cloves using denatured alcohol. They put this oil on paper, which they can take home.

In this investigation of reaction kinetics, learners alter the amount of iodate solution mixed with the same amount of starch solution.

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

In this chemistry demonstration, acid rain is simulated in a petri dish.

Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.

In this activity, learners perform a simulated blood test procedure.

In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.
