Cells Lesson Plan (1) 1 double period Learning Objectives… What are the key topics to be taught……. The parts of a microscope and their functions. Understand the difference between the terms magnification & resolution Content Outcomes Skills Outcomes Students Should be able to… Students Should be able to…. Label a diagram of the parts of a microscope to include; eye piece, barrel, objective lenses, stage, stage clips, focus, base. Give the function of each part above. Understand what is meant by the terms magnification & resolution. Calculate the magnification of an image (from the eye piece and objective lens magnification). Prepare a microscope for use. Focus a microscope at different levels of magnification to view an image clearly. Draw a diagram of a microscopic image appropriately. Common misconceptions with these objectives to watch out for when teaching That microscopes make objects look bigger (magnifies them) but in reality their size does not change. Maginification means increasing the size of an object image, but with this usually comes a loss of resolution (clarity/sharpness). Cross-Curricular Links ICT Opportunities Physics - astronomy Chemistry – examining materials for fatigue e.g. aeroplane wing/engine joints Viewing many microscopic images from google images. Key Vocabulary Use a camera connected to a microscope to project images of everyday objects from students on to white board French microscope Objectif Objectif étape clips scène Glissez lamelle baril se concentrer base grossissement résolution English Microscope Objective Lens Stage Stage clips Slide Cover slip Barrel Focus Base Magnification Resolution Activity Possible teaching strategies 1a) Brainstorm (spider diagram) equipment we use to make things look bigger. Resources/Number of Practical Whiteboard and maybe ppt if necessary to help students visualize. 1b) Brainstorm why we make objects look bigger. 1c) How do microscopes make objects look bigger 2. Look at a microscope and help students to recognize and label microscope parts. 3. Show students how to set up microscopes and focus on objects starting with low power. Get all students to focus on a piece of newspaper writing. ppt slide & worksheets 7A1(Parts of a Microscope, Using the Microscope, Who invented the Microscope?) 12 microscopes Newspaper pieces 4. Explain to students how to calculate magnifications of objects (lens mag x eye piece mag = x …..) and the difference between magnification and resolution. 5. Students examine a variety of either personal or classroom objects, sketch them and calculate a magnification for each one. Plenary Homework Look at examples of each others drawings – what would make them better? Spotlight 7A1 who invented the first microscope? Or Research a commercial use of microscopes Personal objects; e.g. pencil tips, hair, nails, glass pipette ends etc. Safety (including any relevant CLEAPSS card reference for the use of chemicals) Demonstrate clearly to students how to carry microscopes (hands on base and around barrel) and use them to focus correctly without scratching lenses (always look at stage and lenses when moving stage towards lenses- look down eye piece to focus only when moving stage away from lenses). Ensure students do not look directly at the sun or other lights with microscopes. When examining general objects ensure students do not put fluids (especially body ones!!!) on the stage directly to examine.
