This detailed lesson explains how observable features at a microscopic level can be used to classify living organisms into one of the five kingdoms. The engaging PowerPoint and accompanying resources have been designed to cover point 4.2.2 © (i) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply an understanding of the features of the animalia, plantae, fungi, protoctista and prokaryotae kingdoms.
This lesson begins with a knowledge recall as students have to recognise that prior to 1990, kingdom was the highest taxa in the classification hierarchy. Moving forwards, they will recall the names of the five kingdoms and immediately be challenged to split them so that the prokaryotae kingdom is left on its own. An opportunity is taken at this point to check on their prior knowledge of the structure of a bacterial cell from module 2.1.1. These prior knowledge checks are found throughout the lesson (along with current understanding checks) as students are also tested on their knowledge of the structure and function of cellulose. This is found in the section of the lesson where the main constituent of the wall can be used to distinguish between plantae, fungi and prokaryotae. Quick quiz competitions, such as YOU DO THE MATH and SAY WHAT YOU SEE are used to introduce key values and words in a fun and memorable way. The final part of the lesson looks at the protoctista kingdom and students will come to understand how these organisms tend to share a lot of animal or plant-like features.
Both of the accompanying resources have been differentiated to allow students of differing abilities to access the work and this lesson has been written to tie in with the previously uploaded lesson on taxonomic hierarchy and the binomial naming system (4.2.2 a & b).

Module 4.2.2: Classification and evolution (OCR A-level Biology A)
Classification and evolution is a topic that students can find difficult, which may be for a number of reasons that include a lack of engagement during lessons or because these topics are taught quickly as exams approach at the end of year 12. However, a clear understanding is critical, as assessment questions on the content of this module are common and are often worth a significant number of marks. In line with this, the planning of each of the 7 lessons in this bundle has focused on the inclusion of a wide range of tasks that will engage and motivate the students whilst covering the following points as detailed in module 4.2.2 of the OCR A-level Biology A specification: * The biological classification of species * The taxonomic hierarchy * The binomial system of naming species and the advantages of such a system * The features used to classify organisms into the five kingdoms * The evidence that has led to new classification systems, such as the three domains of life * The different types of variation * Using standard deviation to measure the spread of a set of data * Using the Student's t-test to compare means of data values of two populations * Using the Spearman's rank correlation coefficient to consider the relationship of the data * The different types of adaptations of organisms to their environment * The mechanism by which natural selection can affect the characteristics of a population over time * How evolution in some species has implications for human populations If you would like to sample the quality of the lessons included in this bundle, then download the following lessons as these have been uploaded for free: * Taxonomic hierarchy and the binomial naming system * Adaptations & natural selection
