Lesson details
Key learning points
- Quadrats are square frames which can be used to sample plants or slow-moving animals.
- There are different measurements that you can take using a quadrat depending on what you are investigating.
- Most sampling using quadrats is random to avoid bias in your results.
- Classification keys can be used to identify different species.
- The results of ecological sampling can be used to inform conservation and preservation efforts.
Keywords
Quadrat - A quadrat is a square frame which is used to sample populations of plants or slow-moving animals.
Species - A species is a group of organisms that are able to reproduce with each other to produce offspring that are also able to reproduce.
Bias - Bias is when a person carries out an investigation and affects the outcome
Common misconception
Pupils often associate the use of quadrats to survey plants in one type of habitat. Pupils do not consider how they can be used to sample sedentary animals e.g. barnacles / limpets on a rocky shore.
During the slide deck there is reference to how quadrats can be used to sample plants and sedentary animals in different habitats.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
