Lesson details
Key learning points

- Roots provide support for the plant by holding the plant upright, especially in windy conditions.
- Roots absorb water and nutrients from soil to provide the plant with what it needs to grow and stay healthy.
Keywords
Roots - The part of a plant that anchors it in the soil is called the root. Roots take in water and nutrients for the plant.
Function - The task that something has is its function.
Absorb - To absorb is to soak something up.
Nutrient - A nutrient is any substance that plants or animals need in order to live or grow.
Soil - Soil is ground up rock mixed up with plant and animal remains.
Common misconception
Pupils may think that roots are like drinking straws that suck up water through their tips, rather than absorbing it across their whole length.
Share the model used in the lesson of a paper towel absorbing water to help pupils understand that water is absorbed, not sucked up, by the roots. Pupils could experience this for themselves in the classroom to help them understand and remember.
