In this article I am writing on how to make anemometer working model using paper cups – diy – science project exhibition
Making a simple anemometer using paper cups is a fun and educational DIY project. This basic model utilizes the cup anemometer design, which is one of the more straightforward types to construct. Here’s a step-by-step guide to creating your paper cup anemometer:
Materials you will need:
- 4 small paper cups (plastic cups can also work)
- 4 straws
- Pushpin or thumbtack
- Thumbtack with a large flat head (or a small stick and some clay/playdough)
- Ruler
- Scissors
- Tape
- Markers or stickers (optional, for decoration)
Step-by-step instructions:
- Prepare the cups:
- If you’re using plain paper cups, you can decorate them with markers or stickers to make them look more appealing.
- Attach the straws:
- Take the four straws and carefully tape them horizontally to the outside of each paper cup so that they point outwards like spokes on a wheel.
- Assemble the cups:
- Gather the cups together, with the straws pointing outward. Position them in a square or cross shape, with the open ends facing outwards.
- Create the central axis:
- Take the thumbtack with a large flat head (or a small stick and some clay/playdough) and push it through the center of the cups. If using a stick, make sure it is securely attached to the cups with clay or playdough to act as the central axis.
- Mount the anemometer:
- Find a suitable location to set up your anemometer, such as outdoors or near a fan indoors.
- Observe the wind speed:
- When there is wind, the cups will rotate due to the force of the wind. The rotational speed will depend on the wind’s velocity.
- Measure the rotations:
- Use a stopwatch or a timer on your phone to count the number of rotations the anemometer makes in a specific time interval, such as one minute.
- Calculate the wind speed:
- To estimate the wind speed, you can use the formula: Wind Speed (in mph) = Number of rotations per minute × Circumference of the circle formed by the cups (distance covered in one rotation) × Conversion factor.
