Parachuting in

Science Year 5
This unit is part of Year 5 Science May the Forces Be With You

Objectives

Parachuting In
The recovery team needs to parachute in to begin the process of repatriation - but which parachute is best? Your remote team needs to work out the solution.

Science Objectives
i) Explain that unsupported objects fall towards the Earth because of the force of gravity acting between the Earth and the falling object.

ii) Identify the effects of air resistance, that acts between moving surfaces.

Working Scientifically

  1. Plan different types of scientific enquiries to answer questions, including recognising and controlling variables where necessary.
  2. Take measurements, using a range of scientific equipment, with increasing accuracy and precision, taking repeat readings when appropriate.
  3. Record data and results of increasing complexity using scientific diagrams and labels, and tables.
  4. Use test results to make predictions to set up further comparative and fair tests.
  5. Report and present findings from enquiries, including conclusions, causal relationships and explanations of and degree of trust in results, in oral form.

Other Curriculum Areas
Maths

  • Calculate and compare the area of rectangles (including squares) using square centimetres (cm2).
  • Use all four operations to solve problems involving measure using decimal notation, including scaling.
  • Scale speed from cm/second to m/min and km/hr.

Lesson Planning

Teaching

  • Plan an investigation into the effectiveness of various parachutes.
  • Identify variables that need to change and that need to stay constant.
  • Record data using a ‘best of three’ approach.
  • Video record findings offering possible explanations.

Activities

  1. Explore parachutes and air resistance, identifying enquiry questions for investigating effective parachutes.
  2. Set up and carry out a parachute investigation to determine which one travels the slowest (and safest). Recording data and drawing conclusions.
  3. Calculate the area of the parachute and its scaled up speed.
  4. Video recommendations for the best parachute design and materials for the job, based on findings.
