Learning Objective: To investigate the maths to do with parachutes

The original design was sketched by Da Vinci in a notebook in An accompanying note read: "If a man is provided with a length of gummed linen cloth with a length of 12 yards on each side and 12 yards high, he can jump from any great height whatsoever without injury." Leonardo DaVinci’s Parachute Design

1.Take a sheet of fairly stiff paper 30 cm long and 16cm wide. Fold it in half. 2.Open it out and draw a line 1cm along the bottom 3.Cut off this section on the left and leave it on the right – it’s a tab so that you can glue your parachute together. 4.Draw a diagonal line from the centre to each corner. Now fold it along the diagonal - from corner to corner. Make a Parachute Build your own parachute using Leonardo da Vinci's design for the first ever parachute. It looks like a pyramid! Here’s how. 15cm

5. Measure 15cm from the centre along these diagonals, mark this with a cross. 6. Join up the crosses as shown on the diagram and cut out your shape. 7. Fold it into a pyramid shape and selotape in place 8. Attach strings from each corner of the base (use selotape) 9. Attach a weight to these strings Make a Parachute Build your own parachute using Leonardo da Vinci's design for the first ever parachute. It looks like a pyramid! Here’s how. 15cm

Next lesson you will be testing these You will have three trials which you will time Design a data collection table to record your results

Why do modern parachutes not look like the DaVinci parachute?

Choose your shapes or combination of shapes you would like to use to create your parachute. Create your model Calculate the surface area and compare it to the surface area of the DaVinci model

Which launch was more successful and why? – Calculate averages and range to compare your sets of data What other shapes do you think would work well? How would you change your design if you could use any resources you wanted?
