Measurement (length): Saguaro Seeds

Further Challenges

• Watch the related clip below. It shows how seeds can be dispersed by the wind. The sycamore seed has a special rotating wing attached to it that helps carry the seed away from the parent plant (increasing its chance of germination). Instructions for making a ‘helicopter’ seed, like the sycamore, can be found here on the Science Sparks website. Try making a seed and test it outside. Use your measurement skills to see how far away it landed from where it was dropped. Can you calculate an average distance?
