Year 3 Science, Investigating plants, 2 lessons with plans and resources.

Lesson 1: This activity should be used to focus on considering and analysing evidence, rather than planning an investigation. However, it can also be used before the children carry out an investigation of their own to provide them with a good structure for setting up their own tests

Lesson 1: Learning objectives
Children should learn:
• that plants need water but not unlimited water, for
healthy growth
• to use results to draw conclusions
Lesson 1: Learning outcomes
Children will be able to:
• state that plants need water to grow but too much
or too little water may kill them
• describe differences in the way the plants grew

Lesson 2: This activity is intended to support children in their understanding of how simple investigations are planned. Begin the lesson by asking the children to recall any investigations that they have done and the stages of planning that they went through.

Lesson 2: Learning objectives
Children should learn:
• to suggest how a fair test could be carried out
• that in experiments with living things, using just
one plant in each set of conditions does not give
sufficient evidence
Lesson 2: Learning outcomes
Children will be able to:
• recognise the correct order in which to undertake
a simple investigation
• describe factors that contribute to the test
being fair
• suggest why one sample may not be adequate in
each set of conditions
