Teaching activities


  1. Give the children a quick quiz recapping on the following - that plants need light, warmth and water to grow well; that plants need healthy leaves, roots and stems to grow well; that a number of plants need to be used in investigations to provide reliable evidence.
  2. Explain to the children that they are going to label and dissect a flower in the Bitesize life cycles activity.
  3. Watch Learning Zone Class Clips - Reproduction in plants and ask the children to match the names to the parts of the flower.


  1. Explain that reproduction is a process that all living things do. Reproduction of flowering plants is made possible through the processes of pollination, seed production, seed dispersal and germination.
  2. Watch Learning Zone Class Clips - The life cycle of a dandelion. If possible, present this in the context of a story of the life of a flower.
  3. On an interactive whiteboard, open the Bitesize life cycles activity.
  4. Explain briefly the key points and functions of the petal, sepal, nectary, style, stigma, ovary, ovule, anther, filament, receptacle. Show the class how to drag labels to the right parts of the plant.
  5. Click on the Dissect button to show how to pull away each section of the plant.
  6. Explain that rather than destroying a living thing, this online resource is ideal for dissection as no real plant is harmed.
  7. Divide the class into groups with a computer for each group. Allow each group to work through the Label and Dissect screens, taking it in turns within the group to control the mouse. Walk around the groups, talking through problems and encouraging those who have finished early to click on the magnifying glasses to find out more information.


  1. Complete the Label and Dissect screens of the Bitesize life cycles activity as a class on the interactive whiteboard.
  2. Ask the children to identify and explain the functions of each part of the plant. Can they retell that part of the story?
  3. Watch Learning Zone Class Clips - Pollination in plants. Ask the children what the special delivery is (Insects).
  4. Ask the children to act out pollinating plants through insects.


Ask the children to complete the Life cycles worksheet (PDF 65KB) matching the right name and function to each part of the flower.


Ask the children to look for different flowers on their way to and from school. On close inspection, which reproductive parts of a flower can they see? Ask them to report their findings to the class.
