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 make their own flip book that shows real solar flares erupting from the Sun in November 2000. Step-by-step instructions are included with photos.

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.

In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.

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

In this activity (4th activity on the page), learners use their sense of smell to rate and arrange containers filled with different dilutions of a scent (like cologne or fruit juice) in order from wea

In this optics activity, learners explore interference by adding wax blocks to a ripple tank.

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