This lesson uses a step-by-step guide to describe the role of gibberellins in the germination of barley. The PowerPoint and accompanying resource have been planned to cover point (3) of topic 15.2 of the CIE A-level biology specification (for assessment in 2025 - 27).
The lesson begins with a challenge, where the students must identify the term, germination, from a series of clues. They will learn that this is the development of a plant from a seed following a period of dormancy and involves gibberellins. A quick quiz round is then used to introduce the embryo, endosperm and aleurone layer in the structure of a barley seed. The process of seed germination can be divided into a sequence of 9 events and the main task of the lesson challenges the students to order these 9 events. However, this task has an extra level of difficulty as two of the events have been missed out, so the students must use the clues to predict the key biological processes in these events.

Topics 14.2 & 15.2: Homeostasis and control and coordination in plants (CIE A-level biology))
It's fair to say that the plant-based topics are not every students' favourite, so the lessons in this bundle are full of engaging activities and knowledge checks to maintain motivation whilst ensuring that the A-level details are understood. These 5 lessons cover the plant sections of topics 14 and 15 of the CIE A-level biology specification (for assessment in 2025 - 27) and complement each other by building on knowledge attained in the previous lesson.

Topic 15.2: Control and coordination in plants (CIE A-level biology)
This bundle of 3 lessons covers the content of topic 15.2 of the CIE A-level biology specification (for assessment in 2025 - 27). This topic, titled control and coordination in plants, isn't always a student favourite, so additional time has been put into the design and planning to maintain engagement whilst ensuring that the A-level content is covered in detail. A lot of these biological processes are sequences of events, so step-by-step guides are used to aid retention. Understanding checks are found throughout the lessons, as well as prior knowledge checks which challenge content from earlier plant-based topics such as 14.2 and 7. All answers to these checks are embedded into the PowerPoints to allow the students to assess their progress. Topic 15.1, control and coordination in mammals, is also available on here, as well as the larger bundle containing all the topic 15 lessons.

Topic 15: Control and coordination (CIE A-level biology)
These 12 lessons cover points 15.1 (1, 3, 4, 5, 6, 7, 9, 10, 11 & 12) and 15.2 (1, 2 & 3) from topic 15 of CIE A-level biology specification (for assessment in 2025 - 27). This topic is titled control and coordination and concerns comparisons between the endocrine and nervous system in mammals, and then the key structure of the nervous system before looking at this control in plants. Each lesson has been extensively planned and contains a wide range of engaging activities and tasks, interspersed with current and prior knowledge checks. The sensory, motor & intermediate neurones and cholinergic synapses lessons have been shared for free, if you want to download first to get an idea for the quality of these lessons.
