Science: Life cycle of a plant-Seed dispersal
Objectives
Know about the life cycle of
plants, survival needs and
ways seeds are dispersed.
Recreate the different ways
that seeds are dispersed.
Make observations.
Summarise each method.
Starter
What do you think seed
dispersal might mean when
talking about plants?
Teaching
To be done with a class that you work with
frequently or don’t mind providing resources
for.
KS2
Activities
Either let children play with the
different stations on a carousel
to investigate or you could
demonstrate to the class.

When back inside, children to
write a summary of each method
Tell chn that plants that create seeds need to

disperse them over a wide area so that new
available for lower ability.
plants don’t become competition. Revise seed
dispersal methods- wind, animals carrying and
animals consuming.
Tell them about other methods-explosion,
mechanical dispersal (catapult) and water,
showing pictures of examples that do each.
Explain how each method works.
Explain to children that we will be going outside
to investigate the different ways that seeds
disperse. Outside we will have a section for
explosion (coke and mentos), wind (paper
sycamore seed and parachute seeds), water
(waterbombs with seeds in), mechanical
dispersal (catapult) and animals (cuddly toy
with things stuck on). Link to the science when
explaining each section.
