💭What do you think when you see these pictures (on the right)? What makes the skydiver fall to the ground? How can the skydivers land safely?
💬 Share your ideas with your peers, ✍ Record these in your book under the Skydiving forces heading.
✍ Start the worksheet about skydiving forces by drawing a force diagram of a person falling with and without a parachute.
👀 Watch the video clip about how to make a parachute. Making a parachute
✋Make a parachute and test them out recording the landing data on the Skydive into forces worksheet, comparing them to those of your classmates with different shapes and sizes, and without a parachute.
