This is a fun and engaging lesson that uses a range of quick competitions and tasks to ensure that the students recognisethe electrical symbols for the essential components and can describe the functions for each of these. Competitions such as SNAP and SAY WHAT YOU SEE will introduce the students to the components and their symbols. This lesson has been written for GCSE students and looks to build on what they should know from KS3 - however, it could be used with higher ability students at that level.

This is a detailed lesson which looks at the topic of reaction times and guides students through calculating a reaction time using the results of the well known ruler-drop test. In addition, students will see how reaction times can be applied in athletics but also in the calculation of the thinking distance for drivers. The lesson includes an engaging lesson presentation (32 slides) and a student task worksheet. The lesson begins by introducing the key term, reaction time, and teaching students that the average reaction time is 0.2 seconds. Moving forwards, a step by step guide is used to show the students how to take the value for distance travelled by a ruler in the drop test and use the equations of motion and change in velocity equation to calculate the reaction time. There is a large mathematical element to the lesson which challenges the students ability to rearrange formula, convert between units and leave answers to a specified number of significant figures. The answers and methods in obtaining these are always displayed at the end of each task so that the students can assess their understanding and recognise where errors were made if any were. Students will have to follow the provided method to obtain 5 results in the ruler drop test and ultimately find out their own reaction time. The remainder of the lesson looks at how the thinking distance at different speeds can be calculated. This lesson has been written for GCSE students due to the high maths content but could be used with younger students of high ability.

This is an engaging revision lesson which uses a range of exam questions, understanding checks, quick differentiated tasks and quiz competitions to allow students to assess their knowledge of the topic of cells and related topics as covered in the GCSE Biology and GCSE Combined Science courses. As cells are the building blocks of living organisms, a strong understanding of this topic is critical for the success of a student on these two courses. The following topics are covered in this revision lesson: The key differences between eukaryotic and prokaryotic cells The structure of a bacterial cell Specialised cells The individual functions of the organelles Calculating size Students will be engaged through the range of activities which includes quiz competitions such as “CELL, CELL, CELL” where students have to compete to identify specialised cells from descriptions. This lesson can be used at any time during the year as a revision material, in the lead up to mocks or as a final revision lesson before the GCSE terminal exams.
