Growing cress

Science Year 2
This unit is part of Year 2 Science Ready, Steady, Grow!

Objectives

Think about the conditions for healthy plant growth and plant your own cress seeds. Record their growth. How long will it take for them to be long enough to eat?

Science Objectives
i) Observe and describe how seeds and bulbs grow into mature plants.

ii) Find out and describe how plants need water, light and a suitable temperature to grow and stay healthy.

Working Scientifically

  1. Ask simple questions and recognise that they can be answered in different ways.
  2. Observe closely, using simple equipment.
  3. Perform simple tests.
  4. Identify and classify.
  5. Use their observations and ideas to suggest answers to questions.
  6. Gather and record data to help answer questions.

Lesson Planning

Teaching

  • Recall knowledge about plants’ needs.
  • Know what cress seeds need and plant them in contrasting locations.
  • Make predictions about cress growth and keep records

Activities

  1. Understand what plants need to be healthy.
  2. Know that cress seeds need water and the right temperature to germinate and grow.
  3. Predict, and begin to give reasons for what will happen to the cress in the dark cupboard.
  4. Start a record of the cress growth.

Investigation - exploring over time, pattern seeking, problem solving
Place one egg shell with cress in a cupboard and talk about what might happen to the cress and its growth.
Start a record of the cress growth and predict how long it will take for the cress to grow long enough to eat.
