This fully-resourced lesson describes the differences between resolution and magnification, with reference to light and electron microscopy and the engaging PowerPoint and accompanying resources have been designed to cover the content of point 1.1 (d) of the CIE A-level Biology specification.
To promote engagement and focus throughout these 3 lessons in topic 1.1 (The microscope in cell studies), the PowerPoint includes an ongoing quiz competition and a score sheet is found within the resources to keep track of the cumulative scores. The quiz rounds found in this lesson will introduce the objective lens powers, the names of the parts of a light microscope and emphasise some of the other key terms such as resolution. The final round checks on their understanding of the different numbers that were mentioned in the lesson, namely the differing maximum magnifications and resolutions. Time is taken to explain the meaning of both of these microscopic terms so that students will understand their importance when looking at the cell structures in topic 1.2. By the end of the lesson, the students will be able to explain how a light microscope uses light to form an image and will understand how electrons transmitted through a specimen or across the surface will form an image with a TEM or a SEM respectively.
As detailed above, this lesson has been written to tie in with the previous lesson on measuring cells and units as well as the next lesson on calculating actual size.

Topics 1 & 2: Cell structure & Biological molecules (CIE A-level Biology)
It's no coincidence that cell structure and biological molecules find themselves as topics 1 and 2 of the CIE A-level Biology course, because a clear understanding of their content is absolutely critical to promote success with the 17 topics that follow. Hours and hours of intricate planning has gone into the 18 lessons included in this bundle to ensure that the detailed content is relevant and can be understood and that links are made to related sections of topics 3 - 19. The lesson PowerPoints and accompanying resources contain a wide range of activities that include: * differentiated exam-style questions with clear mark schemes * directed discussion points * quiz competitions to introduce key terms and values * current understanding and prior knowledge checks Due to the detail included in these lessons, it is estimated that it will take in excess of 2 months of allocated teaching time to cover the content of the resources A number of the resources have been shared for free so these can be downloaded in order to sample the quality of the lessons

Topic 1: Cell structure (CIE A-level Biology)
As Biology is the study of living organisms which are built out of cells, a clear understanding of the topic of cell structure is critical for a student's success in A-level Biology. Intricate planning has gone into all 7 of the lessons included in this bundle and the variety of tasks will engage and motivate the students whilst the details of the following specification points in topic 1 of the CIE A-level Biology course are covered: **Topic 1.1: The microscope in cell studies** * Use an eyepiece graticule and stage micrometer to measure cells * Use of the millimetre, micrometre and nanometre * Distinguish between resolution and magnification * The use of light and electron microscopes * Calculate the actual sizes of specimens **Topic 1.2: Cells as the basic units of living organisms** * Recognise eukaryotic cell structures and outline their functions * State that ATP is produced in the mitochondria and the chloroplast and the role of this molecule in cells * The structure of a typical prokaryotic cell * The differences between eukaryotic and prokaryotic cells * The key features of viruses If you would like to sample the quality of these lessons, download the magnification and resolution lesson, the eukaryotic cell structures lesson and the viruses lesson as these have been shared for free
