### SKY DIVING - Number Loving

```Learning Objective:
To investigate the maths to
do with parachutes
Leonardo DaVinci’s Parachute Design
The original design was sketched by Da Vinci in a
notebook in 1483.
"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."
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
15cm
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.

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
• 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.
