Magnifying Tools
Use hand lenses, microscopes, and digital images, and what magnification means.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 32
- Magnify means to make something look bigger. A hand lens might show things ten times bigger, written 10×.
- A microscope goes much further. Look at a leaf at higher and higher power. At 100×, cells appear.
- At 400×, you can see inside a single cell.
- To find the total power, multiply. A 10× eyepiece with a 40× lens gives 400×. Digital microscopes also show images on a screen.
Georgia Standards of Excellence in Science:
- S5L3.a — Gather evidence by utilizing technology tools to support a claim that plants and animals are comprised of cells too small to be seen without magnification.
