Sc 2 (Life Processes and living things) Yr. 3

Statutory Requirements.

Pupils should be taught to:

  • Explore the part that flowers play in the life cycle of flowering plants, including pollination, seed formation and seed dispersal

What you do

  • See the video clip on the website: www.practicalprimaryscience.co.uk
  • Demonstrate to the childen how to cut out the sycamore keys paying particular attention to the cut and fold procedures.
  • Demostrate exactly how the investigation should be carried out paying particular attention to “fair testing” procedures.

Group /Class organisation

  • Depending on the number of adult helpers and apparatus available will determine how many groups of three / four children will take part in this practical activity.
  • If limited help is available then other children not involved directly in the practical activity should be engaged in direct observation exercises e.g. making detailed sketches of sycamore seeds collected from the Nature Walk…..if conducted in the Autumn.

How it works

  • The longer the wings of the sycamore seed (helicopter) the longer it takes to reach the ground, because of the upthrust of the air on the wings.

Preliminary Activities

  • Collection of Autumn fruits/seeds from a Nature Walk….ideal for an Autumn project as it puts the children at the centre of the learning process.

Follow up work

  • An investigation into other forms of seed dispersal
