A Great STEM Activity for All Ages!

The beauty of homeschooling is that it allows you to tailor your lessons to your child’s age and abilities. The anemometer-building experiment can be scaffolded to suit the needs of children of various ages, making it a versatile and engaging science activity for homeschooling families. See the list below for a summary of how you can use this experiment with your own homeschooling child.

Preschool (ages 3-5)

Children of this age will likely require assistance when building the anemometer.

While working on the project together, take the opportunity to engage them in a conversation about the concept of wind and its effects. You can explain what happens when the wind blows and how it influences various objects.

Once the anemometer is assembled, head outside. Encourage your children to observe their homemade anemometer as it spins in response to the wind.

Use this opportunity to draw the connection between the anemometer’s rotation and the speed of the wind. Explain that as the anemometer spins faster, it indicates that the wind is blowing at a higher speed. This real-world observation will help them grasp the practical application of their science project and deepen their understanding of the relationship between the anemometer and wind speed.

Early Elementary (ages 6-8)

Children this age can build the anemometer with little help. Once the anemometer is constructed, take the learning experience outdoors. Encourage them to observe the anemometer closely as it starts spinning in response to the wind.

At this age, discussing several key points that enhance their understanding is beneficial. First, introduce them to the concept of wind direction, explaining how they can determine which way the wind is blowing by observing the anemometer’s rotation; for instance, a clockwise spin indicates wind coming from the right.

Next, discuss wind speed, clarifying that a faster-spinning anemometer signifies stronger winds. Have children talk about how the wind feels on their faces.

Furthermore, connect their learning to real-life applications, sharing examples of why understanding wind speed and direction matters, such as weather forecasting and sailing.

Finally, empower them by explaining that they are little scientists in action, actively collecting data and making observations, much like professional scientists. Encourage them to ask questions and formulate hypotheses based on their observations.

Upper Elementary/Middle School (ages 9-12)

Middle school-age children are ready to take their anemometer project to the next level.

At this stage, they can independently build the anemometer and have the freedom to make adjustments as they observe it in action.

Encourage them to build the device and formulate hypotheses about its performance. Ask, “What do you think will happen when we use this anemometer?” This encourages critical thinking and hypothesis-testing skills, crucial in scientific inquiry.

Explain the importance of data collection. Provide them with the attached worksheets that guide them in recording their observations. Additionally, introduce them to the concept of data conversion, explaining how to translate the anemometer’s rotations into meaningful wind speed measurements.

Discuss the importance of instrument calibration, explaining how it ensures precision in scientific instruments like the anemometer. Discuss why calibration is essential for obtaining reliable data.

This is an excellent opportunity to rope in the steps of the scientific method. Encourage them to form hypotheses, design experiments, collect data, and analyze results, instilling in them the fundamental approach to scientific investigation. Invite them to measure wind speed at home and at a second location. They can then compare the two.

Connect their learning to real-world scenarios by discussing how understanding wind speed and direction plays a pivotal role in weather forecasting and climatology. Explore how meteorologists utilize anemometers to make predictions and decipher intricate weather patterns. You can also explain the significance of wind in biology, mainly how it serves as a crucial mechanism for dispersing seeds.
