Make An Anemometer Weather Science Experiment
In this fun and easy science experiment, we’re going to explore and investigate weather by making an anemometer.
- Needle or thin nail
- Lump of modeling clay
- Small block of wood for your base
- Foil muffin cups
- Piece of cardboard
- One brightly colored sticker
- Set the block of wood on a flat surface or table. This will be the base of your anemometer.
- Place the lump of modeling clay in the center of your block of wood.
- Stick the pencil into the modeling clay with the eraser pointed up. Mold the clay around the pencil so it is secure and straight up and down.
- Cut two strips of cardboard sixteen inches long and two inches wide.
- Use a drop or two of glue to fasten the two strips together in the shape of a cross.
- Now push the pin or nail through the center of the cross into the eraser. The cross should spin freely.
- Tape a foil muffin cup to each end of the cross making sure all of the cups are facing in the same direction.
- Set you anemometer outside and begin documenting the wind speed each day.
- To measure the wind speed for this demonstration, use the stopwatch to count the number of rotations per minute.
How it Works:
An anemometer is a meteorological instrument. An anemometer is used to measure wind speed. When the wind blows, it causes the foil muffin cups to spin. As you count the number of rotations, you are able to determine higher and lower wind speeds.
Make This A Science Project:
Try recording winds speeds (rotations of the foil cups) at different times of the day. Try recording winds speeds (rotations of the foil cups) at different times and seasons of the year.
