Sight: Stained Glass
This activity will help you to explore the sense of sight
Equipment You Will Need
- PVA glue
- Coloured tissue paper
- Tracing paper
What you need to do
1. Assemble your materials
2. Look at the different colours of tissue paper, what colours can you see?
3. Tape your sheet of tracing paper to the board. Brush a little PVA glue over your sheet of tracing paper.
4. Tear the tissue paper into small pieces
5. Glue pieces of tissue paper onto the tracing paper, adding more glue when necessary until your whole sheet is covered.
6. Wait for it to dry
7. Hold it up to the light!
What is happening?
When light hits an object – like your coloured tissue paper – the object absorbs some of the light and reflects the rest of it. When you look at your stained glass, the wavelengths of reflected light determine what colour you see. The light waves reflect off the stained glass and hit the light-sensitive retina at the back of your eye.
Why is colour important?
Although our distant ancestors probably first used colour vision to find fruit in trees, it is still useful to us. Colours are used to send all sorts of important messages in the modern world. Traffic lights turn from green to red to tell us to stop and warning lights turn orange on the car dashboard. Colour is also beautiful – think how much time we spend admiring sunsets, art, and landscapes, and how much less-impressive firework displays would look in black and white.
