Lesson Details

Key learning points

Plants depend on their environment to provide what they need to grow and survive.
Changes to environments can cause danger to the plants within them.
Scientists use several methods to count and study the number of plants in an environment including surveys and sampling.
A quadrat can be used in different locations to help get an accurate estimate of plant numbers.

Common misconception

Children sometimes don't realise plants can be in danger as well as animals.

Share the examples in the slide deck and give pupils time to research other plants to discover there are lots of different plants in different environments that are in danger. If time, find out if any plants in your local area are in danger.
