Actual Length Learning Objective (LO) Use a formula to calculate actual length Success Criteria (SC) I can compare magnified images I can calculate actual length I can rearrange a formula to calculate magnification. Key Words Magnification, units
Questions How might it be possible to see images of objects that are very small? How might maths be used in the study of magnified images? http://t2.gstatic.com/images?q=tbn:ANd9GcRJ-ZaAHTbEin73TvnvkhHO1BkaIbP2psJ4k0rCZmxd5mWpKdBK5D1D8HbB:www.bestsciencesupplies.com/images/firsttemplate/scientist%2520with%2520microscope.jpg
Magnification Study the eight images of objects. Most of them can only be seen when magnified by a light microscope or electron microscope. Task 1 Rank the images in order from largest to smallest.
How big? The animation showed different scales of measurement: 1mm = 1000 m (micrometers) 1cm = 10mm How many m in 1cm?
Actual Size Actual size = measured length magnification Magnification = measured length actual size
20 0.002 = x10,000 10 0.006 = x1,666.67 Object Measured Size Actual size Magnification 300 0.01 = x30,000 E Coli 20mm 0.002mm x Yeast Cell 10mm 0.006mm x Blood cell 300mm 0.01mm x 40 0.5 = x80 Pollen Grain 40mm 0.5mm x 6 3.5 = x x1.7 Hair 6cm 3.5cm
