Then try to design your own whirlybird-one that falls as slowly as possible. For example, what happens if you make the "wings" longer or shorter or narrower or wider? What if you make the edges of the wings wavy or zigzagged instead of straight? What if you make the wings curved instead of rectangular? Try out a bunch of different ideas to see what happens. Extra: Try modifying the whirlybird template or making your own design.Do the different types of paper fall at different speeds? Extra: Try making whirlybirds from different types of paper, such as printer paper, construction paper and cardstock.Write down the times to help you remember how fast it falls when you add different numbers of paper clips. You can also use a stopwatch to time how long it takes the whirlybird to fall with different numbers of paper clips on it.What do you observe as you add more and more paper clips? Keep adding paper clips, one at a time, to your whirlybird and drop it after each new paper clip.How did it fall with a paper clip attached? Do you think it will fall faster? Pay close attention. Now, attach a paper clip to the bottom part of the whirlybird and drop it again.Why do you think it is important to drop it more than once? Now drop the whirlybird a couple more times-in the same fashion, from the same height.Now it's time to drop your whirlybird! What do you think will happen when it gets dropped? Have an adult help drop it from a safe high place (such as standing on a chair or a stepping stool).Follow the directions on the template to cut out and fold your whirlybird.

If you do not have access to a printer, you can download the file and open it on your computer, then use a pencil and ruler to draw the whirlybird shape on a piece of paper, based on the dimensions in the template.

In this activity you will build a simple paper helicopter called a "whirlybird." Unlike a real helicopter, the whirlybird does not have a motor to make its blades spin. Aircraft such as helicopters with spinning blades are called rotary wing, unlike traditional airplanes, which are fixed wing. Helicopters stay in the air using spinning blades that are used to generate "lift." With enough of it, a craft can overcome the force of gravity, which pulls the object down toward Earth.

And you will learn a little bit about what keeps these amazing vehicles aloft. Have you ever seen a helicopter flying through the air? Have you ever wondered how they fly-or if you could try flying one yourself? This fun activity will help you get started at home building a simple paper helicopter.
