Beach windmill template

Once you have arrived at the ideal number and pitch, you may decide to glue them in place. How much difference does the number of blades make? Or the angle that blades are pitched at? Or the distance from the fan? We created a table for conducting the experiment and counted how many times the windmill would turn in half a minute, after we made adjustments to the the blades.

To make counting easier, you might want to colour one of the blades with marker on the back. According to our experiment, adjusting the pitch of the blades make more difference than the number of blades did. Before, I would have guessed the opposite. Here is another short video of us adjusting the blades.

Aside from the coloured version, our tutorial includes a template that children can colour themselves. If you do make a coloured windmill, please, share it with us! I would love to make these with my year six class this term. Please advise how to access the template.

Making a craft that actually moves is sure to entertain even the youngest of kids, and with the help of a household fan, our windmill flew. Now, what dolly can I put inside? Experimenting with the blades presents a good opportunity for a little scientific study.

How does the number of blades affect the speed of rotation? How does the pitch? And the distance from the fan? How to Make a Windmill Model. Thread a small bead on the back of the paper fastener. Make a hole near the top of your cardboard tube. Push the paper fastener in the hole and fold the ends back to stop it from coming out again. You can decorate the cardboard tube to make it more colourful. You might also like.
