Why Teachers Avoid Experiments & Demos

• Preparation – setting up a lab takes too long

• Materials – the equipment is not available

• Failure – it might not go as planned

• Risk – some activities are too dangerous

• Cost – it is too expensive to supply the class with the materials

• Content – I have too much material to cover

• Knowledge – I do not have enough background in science

Why We Should Use Experiments & Activities

Because getting into it is the

whole point of Science!

The application of the scientific method is the means by which the content of science is discovered.

And …It’s a lot more exciting that way.

Scientific processes engage the learner and require active learning…..

MYSTERIOUS GLOWING BALL

• Persistence of vision– White light appears to break down into its

component colors– Humans see three colors and all other shades

are a blend of these colors– Check out a TV set – Check out a painting by Seurat (a pointillist)

UV BEADS

• Explore the nature of sunlight or the effects of UV radiation

• Test with different SPF sunscreens while exposed to sunlight or UV

Hanging a Hammer

Magnet FUN• A great demonstration to show how a

magnetic force can cause an acceleration

• Or to slow a falling object.
