The Edge is celebrating the International Year of Light and National Science Week with 6 inspired workshop plans for you to download and use for free. Using complex ideas but simple techniques, you can create hands–on experiments and DIY devices to explore this fundamental science.
Keep reading below for the list of available science week workshop plans, or download them here.
Light always travels in a straight line, but sometimes it goes around corners. Explore what happens when light travels from one substance to another and how this makes rainbows, optical fibres and elusive fish.
Create and ever changing mosaic of colour with this classic optical toy you can make in a few minutes from cardboard, scraps of plastic and a few coloured beads.
Waves of Light
You can feel energy travelling in water waves, and hear it in sound waves, and light energy travels in waves, too. Use the properties of light waves to make interesting things happen, using flyscreen, sheets of perspex and 3-D glasses.
See what is happening over the fence, and around the corner with this simple periscope design that uses plastic mirrors and a cardboard template (not suitable for submarines).
Light can come from many different sources, and this simple spectroscope made using a cardboard template and a piece of a CD disc will reveal how each type of light is different by revealing its unique spectrum.
The Colour White
We see millions of colours on our screens, and even more in nature, but how does the white light from the sun or an LED make that possible? Combine colours using torches and build a colour spinner to find out how the colour white is made.
