Materials Needed

Two identical potted plants (small herbs work well)

Observation chart
Crayons for recording
Labels: 'Watered' and 'No Water'
Camera (optional)

Preparation

1Choose two healthy, identical plants

3Create simple observation chart with days of the week
4Place plants in same location with same light

Step-by-Step Instructions

1Show children both plants and explain the experiment
2Water one plant daily, leave the other dry
3Each day, observe changes together
4Children draw what they see on the observation chart
5Discuss: 'What do you notice? Why do you think this is happening?'
6After one week, discuss what plants need to stay healthy

Assessment

Can the child observe and describe changes in the plants?
Does the child understand that plants need water?
Can the child predict what will happen?

Extensions

Discuss how animals also need water and brainstorm where they find it
Look for signs of animals getting water around school
Create a 'Water is Important' poster
Water the school garden together

Teaching Tips

Don't let the plant die completely - water it after the experiment
Connect to children's experience of being thirsty
Use simple vocabulary: 'healthy', 'droopy', 'strong'
Take photos to document changes
