How high will it go?

Finding the height achieved by a flying object using trigonometry.

In this activity learners will work out the height of a released balloon using a clinometer and trigonometry. This is one of a series of resources designed to allow learners to use the theme of the future of flight to develop their knowledge and skills in in Design and Technology, Engineering and Mathematics.

This activity could be used as a main lesson activity to teach learners about the practical application of trigonometry. It could also be used as part of an introduction to the use of trigonometry within engineering.

You will need:

  • Thin card
  • Balloons
  • Balloon pump, if required
  • Brass split pin paper fasteners
  • Scissors
  • Sharp pencils and erasers
  • Calculators
  • Tape measure

And please do share your learning highlights and final creations with us on social media @IETeducation or send them via email to to be featured in our online gallery.
