Sometimes strong, sometimes soft, the wind blows in different directions and strengths. Today’s experiment, the kids will learn to make an anemometer – a device to measure wind speed. See if they could make a weather forecast from it too!
What you'll need:
- A white plastic bottle
- A wooden kebab skewer
- A Straw
- A pencil
- A marker pen
- Some sticky tape
In 6 easy steps construct an Anemometer:
- Cut a ring from the plastic bottle and split it in half
- Turn over one of the halves and attach the skewer down the middle.
- Make a hole in the middle of the bottle top, push the skewer through it and screw the top back on the bottle
- Draw 3 lines of dots on the bottle – 1 dot near the bottle top, 4 dots in the 2nd line and 8 dots along the edge
- Slip the skewer into the straw
- Hold the anemometer by the straw lightly to let it catch the wind.
