Homeostasis and Response Lessons PowerPoint | AQA GCSE Combined Science Biology B5, 9 Lessons
AQA GCSE Combined Science Biology B5 Homeostasis and Response: 9 lessons ready to teach, with a topic test
This is the Combined Science Trilogy version of B5 Homeostasis and Response, matched to the AQA 8464 specification. You get 8 teaching lessons and the 1 required practical as full lessons, all planned and ready to teach in editable PowerPoint.
What your classes work through
- The nervous system and reflex arc. Pupils set a hand jerking off a hot pan against deliberately lifting it with a cloth and explain the speed difference.
- The human endocrine system. Pupils decide how a newly found messenger released straight into the bloodstream travels and how fast it works, from four options.
- Controlling blood glucose. Pupils take readings at 30 and 90 minutes after a glucose drink and work out how quickly blood glucose falls without diabetes.
- Hormones in human reproduction. Pupils track progesterone through the second half of a cycle with no fertilisation and link its fall to the uterus lining breaking down.
- Contraception. Pupils account for how the hormones in a daily combined pill stop eggs maturing and being released, so pregnancy does not happen.
- Using hormones to treat infertility. Pupils test a student's conclusion about IVF against clinic data showing that 25 of 100 couples had a baby.
- Feedback systems. Pupils describe how negative feedback raises a low thyroxine level and explain why the level then stops rising too high.
- Homeostasis and optimum levels. Pupils turn single-word gaps into full explanations of how the body detects overheating and brings its temperature back down on a hot day.
The 1 required practical
- RP6 Reaction Time. Pupils add five ruler drop distances and divide by five to find the mean result from a reaction time test.
Who it is for
Use it for AQA GCSE Combined Science Trilogy B5 Homeostasis and Response lessons on the nervous system, reflexes, hormones, blood glucose, the menstrual cycle, contraception and infertility. It fits Combined Science Biology revision for KS4 and includes the reaction time required practical.
How each lesson runs
Each B5 Homeostasis and Response lesson starts with a Do Now that recalls earlier learning, with the answers on the next slide. It then moves through I Do, We Do and You Do, with a model answer after each task. It finishes with the AQA-style question listed above, its mark scheme and an exit ticket. A specification slide names the AQA points the lesson covers, so you can check it against your scheme of work.
Topic test
The B5 Homeostasis and Response topic test covers the whole unit with AQA-style questions and comes with its mark scheme, both in Word and PDF.
