anemometer working model using paper cups

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:

1. Prepare the cups:
• If you’re using plain paper cups, you can decorate them with markers or stickers to make them look more appealing.
2. 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.
3. 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.
4. 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.
5. Mount the anemometer:
• Find a suitable location to set up your anemometer, such as outdoors or near a fan indoors.
6. 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.
7. 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.
8. 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.
