More about flowers

Science Year 3
This unit is part of Year 3 Science Artful Flowers, Fruits and Seeds

Objectives

Learn how insects and other creatures are important in the pollination of flowers. Discover the secrets of how bees communicate using a waggle dance and give it a go yourself. Create some stunning bee and flower models.

Science Objectives
i) Explore the part that flowers play in the life cycle of flowering plants.

Working Scientifically

  1. Identify differences, similarities or changes related to simple scientific ideas and processes.

Lesson Planning

Teaching

  • Understand that flowers vary in size, colour, shape and form but all play a crucial role in reproduction..

Activities

  1. Discover the role played by insects in pollination.
  2. Learn to do a bee Waggle Dance and know this is how they communicate with other bees.
  3. Create 3D models of either flowers or bees.
  4. Play a waggle dance game to communicate the location of a target “flower”.

Investigation - analysing secondary sources/observation
Identify male and female parts and learn their function. Make model flowers and insect puppets for the exhibition. Use puppets and models to demonstrate pollination.

Vocabulary
