Make an anemometer Follow FizzicsEd 150 Science Experiments: Comments 0 You will need: 4 plastic cups (we used 30mL biodegradable cups) A sharp pencil Two cardboard strips (at least 20 x 3cm each) Stapler A boxcutter & adult help Thumbtack (optional) Copyright Instruction 1 Form the two cardboard strips into a cross. Use at least two staples to join them together. Optional: You can use the thumbtack to make a small hole through the middle of the cardboard strips. 2 Use the stapler to attach a plastic cup on the end of each strip of cardboard. 3 Make sure that the plastic cups are all facing the same way. 4 Push the pencil into the centre of the cardboard cross. 5 Take the anemometer out into a breeze and see if it spins! Extra tip: Colour one of the cups so that you can count it every time it passes in front of you. 6 School science visits since 2004! – Curriculum-linked & award-winning incursions.– Over 40 primary & high school programs to choose from.– Designed by experienced educators.– Over 2 million students reached.– Face to face incursions & online programs available.– Early learning centre visits too! 7 Online courses for teachers & parents – Help students learn how science really works 8 Get the Unit of Work on Pressure here! Want to dive into air pressure? It’s all about air pressure in many ways! From how storms form to how planes fly, this unit covers many concepts about air pressure. Includes cross-curricular teaching ideas, student quizzes, a sample marking rubric, scope & sequences & more What is going on? The stronger the wind, the faster your anemometer moves! Design In this design, the friction between the pencil and the cardboard strips does cause the anemometer to not spin as fast as it could. Can you design a better version? Share your ideas below! Variables to investigate More on variables here Can you reduce the friction between the pencil and the cardboard? What happens if you increase the cup size? Measure the wind speed Measure the length of one cardboard arm that holds a cup. This is the radius of the circle that the cups travel around. Work out the circle circumference of the travelling cups by using the formula below:Circumference = 2 x Pi x radius (where Pi = 3.14 as an approximation) Count the number of revolutions in one minute (rpm) Substitute your answers into the formula below to work out the wind speed of your anemometer:Wind speed (km/hr) = (rpm x circumference x 60 minutes) / 1000 meters Worked example Eg: If an anemometer spins 90 times in 1 minute, and it has a measured circumference of 1 metre… Wind speed (km/hr) = 90 rpm x 1 meter x 60 minutes / 1000 metres = 5.4 km per hour How can you measure wind speed without an anemometer? The Beaufort scale is a way that you can roughly work out the wind speed based on what you can see happening in the environment around you. Learn more! It’s all about pressure!
