Teaching activities
Introduction
Show children the display of a plant. Ask for volunteers to use the labels of
the main parts of a plant to identify the correct part. This reinforces prior
learning. Ask the children if they can remember the LAW for plants. This is
Light, Air and Water, which all plants need for growth. Tell children they are
going to look at the effect of water, temperature and light on plant growth and
observe how the plant grows.
Activities
Divide the class into groups with computers. For each group, set up the
Helping plants grow well online activity. Show the children how to adjust the
amount of water, heat and light. Ask the children to predict what will happen
if the plant has 1) no light, 2) no water and 3) no heat. Ask them to find out
if their predictions were correct. How are you going to do this (reduce one
variable, but keep the others topped up)? What do you need to keep the same in
order to carry out a fair test?
Plenary
Were your predictions correct? What happened to the plant with 1) no light, 2)
no heat and 3) no water? Encourage observations of colour, shape and size and
reference to the main parts of the plant. Record comments and observations for
display.

Extension
Hand children copies of the Helping plants grow well worksheet. Answer any
questions children may have and, when they know what to do, let them complete
the worksheet independently.

Suggested homework
Ask children to take responsibility for a plant at home, recording the amount
of light, temperature and water every day, and writing up their observations in
a table.
