Control of the oestrous cycle & feedback in females

PowerPoint and activity introducing 'The principles of feedback mechanisms' and ' Control of the oestrous cycle'.

Students often find this especially challenging and it took me a while to come up with an effective lesson that helped students remember the interaction between the hormones involved in the control of the oestrous cycle. This resource takes about 2.5-3 hours to work through, but some of the activities can be done independently.

The PPT begins introducing positive and negative feedback, with a few examples of milk let down and birth.

Then, there is a card sort activity, which is supported with matching the cards with various sections on the graphs.

There's a few exam questions and an application activity about 'The oestrous cycle in pigs' near the end.

This resource also comes with a fully editable version of the accompanying student notes, which contains another application type activity and a selection of past examination (AQA) questions & marks scheme.
