Sense and response

During lockdown I’ve had time to prepare lots of lesson plans and resources. This one has had lots of positive feedback from colleagues and requests that I share it, so that’s what I’m doing.

This lesson, about how organisms sense changes in their environment (both internal and external) and respond, is suitable for combined science students and biology (separate science) students.

The curriculums of the various exam boards vary slightly, so I chose to focus here on the learning objectives of topic B5.2 of the OCR ‘ Twenty First Century Science’ course – GCSE (9-1) Combined Science B.


If you like the presentation and would like to pull it apart and re-use bits of it in your own lessons that’s fine.

Students under 18

I hope you find this lesson interesting. There are quizzes and surveys in the lesson that you may skip or choose to complete. If you complete them, when you’re asked for your name, enter ‘anonymous’ or use a nickname. I’ll provide feedback in the comments on this page. I will not receive any information that identifies you: IP, location, email, etc.
