Parachutes

Eggy parachute Investigation

LEARNING OBJECTIVES

Children should learn:

  • that when an object falls, air resistance acts in the opposite direction to the weight
  • to check measurements by repeating them
  • to create a graph to show their findings to interpret the graph in conclusion.

YOUR CHALLENGE THIS WEEK

Create a fair test to investigate air resistance providing Eggy Bond with a parachute to land 'safely'.

Extra care needs to be exercised to prevent Eggy from having a similar mishap as his distant 'eggsin' Humpty Dumpty.

Make use of your prior knowledge (space probe investigation) and discuss your ideas about forces in action when a parachute falls.

Choose a force to investigate eg, air resistance.

Decide on a testable question eg, does the size of the canopy effect the speed a parachute descends?

Design a fair test

Medium
Adjust the catapult to create more tension/potential energy.

Mild
Create a pegs catapult which suggest how to create greater tension.


Bring in equipment and egg to make parachute.

Design and make the parachute.

Make a prediction.

Investigate

Record

Interpret and reach a conclusion based on scientific understanding.


VOCABULARY
air resistance, canopy, parachute, gravity, inflate, terminal velocity, area, descent.

EAL

Some questions to consider.

What are the two forces acting on an object when it is falling?

Gravity is always the same, so how can we increase or decrease the speed at which an object falls?

What would a force diagram of a skydiver look like? How would it be different before and after deploying the parachute?

What variables affect the speed at which a parachute descends?

Post your answers and any other helpful ideas in the comment section below.

Good luck with your challenge and
'MAY THE FORCE BE WITH YOU.'
