KS2 Science at Home: Week 10

Key Stage 2 Experiment of the Week! – Parachute


How does it work?  

When you release the parachute the weight pulls down on the strings and opens up a large surface area of material that uses air resistance to slow it down. The larger the surface area the more air resistance and the slower the parachute will drop.

Cutting a small hole in the middle of the parachute will allow air to slowly pass through it rather than spilling out over one side, this should help the parachute fall straighter.

Materials you need

  • A plastic bag or light material
  • Scissors
  • String
  • A small object to act as the weight, a little action figure would be perfect


  1. Cut out a large square from your plastic bag or material.
  1. Trim the edges so it looks like an octagon (an eight sided shape).
  1. Cut a small whole near the edge of each side.
  1. Attach 8 pieces of string of the same length to each of the holes.
  1. Tie the pieces of string to the object you are using as a weight.
  1. Use a chair or find a high spot to drop your parachute and test how well it worked, remember that you want it to drop as slow as possible.

Key Vocabulary

Air resistance: A force that acts in the opposite direction of moving object.

Surface area: The total of all the areas of each of the sides of an object.
