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

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

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.
