|---|---|---|---|---|---|
| Compound Light Microscope | Consists of a tube with lenses, and a light source - it magnifies the image
🗑
|
||||
| Electron Microscope | Tiny particles of matter are used to magnify images
🗑
|
||||
| Transmission Electron Microscope | Electrons pass through the specimen and produce a flat image - can magnify up to 200,000 times the actual size
🗑
|
||||
| Scanning Electron Microscope | Electrons bounce off the surface of the specimen and a three-dimensional [3-D] image is produced - can magnify up to 100,000 times the actual size
🗑
|
||||
| X-Rays | Used for almost a century to see internal structures of organisms [bones, heart, lungs] and the structures of proteins
🗑
|
||||
| CT Scans [Computerized Tomography] | Low dosage x-ray beams are passed through the body at different angles, and often a dye is injected to help highlight tissues - provides a clearer, more detailed image than x-rays - useful for studying brain and spinal tissue
🗑
|
||||
| MRI [magnetic resonance imaging] | provides a clearer image than x-rays by using short bursts of magnetic field - useful for studying brain and spinal tissue
🗑
|
||||
| Computers | Can collect, store, organize, and analyze information - can create graphs, solve math problems, and analyze data - With the help of computers, life scientists are able to solve problems that they weren't able to solve in the past

Liquid is measured in Liters
Solid objects are measured in cubic meter [m3] or cubic centimeters [cm3]
🗑
|
||||
| Mass | The amount of matter in an object

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
