Plants without water

You can find out and describe what happens when plants do not have water.

Lesson details

Key learning points

  1. Plants are living things, they need water to grow, stay alive and and keep healthy.
  2. Without water, a plant can dry out, drop leaves, lose its strength and begin to wilt.
  3. Changes in plant growth can be compared and described using observation skills.
  4. Different plants can survive without water for different amounts of time.
  5. Unhealthy plants without water can sometimes be recovered with water within a short period of time.

Common misconception

Pupils may think that plants need lots of water everyday

Remind pupils that different plants need different amounts of water, and a plant with too much, or not enough, water could become unhealthy

Keywords

  • Plant - A plant is a living thing that often has roots, stem and leaves.

  • Water - All living things need water to stay alive.

  • Survive - A plant will survive, or stay alive, when it has everything it needs.

  • Compare - When we compare, we look at what is the same and what is different about at least two things.

  • Record - We record in science to keep information so that it can be looked at again.

Pupils will be observing the plants growing without water since lesson 3. They will compare these to the plants growing with everything (water, warmth and light). They will add today's observations without water to their chosen method from lesson 4
Teacher tip

Equipment

Pupils will need equipment for their chosen method of recording (ipads, drawing materials etc.)
