- Describe the compound light microscope
-
magnification:5x1000x
How it works/discription:*made of a tube with lenses stage, and a light
*specimen is placed on the stage, light passes through, and the lenses magnify
Uses:*To observe things that are too small to see with the naked eye.
*Looking at pond, water, blood samples, tissue samples (living things)
- How are the images created by electron microscopes different than compound microscopes?
- Electron microscopes are abl to see up to 200,000 x and provides clear highly magnified images which are none living samples where the compound light microscope magnifies 5x 1000x and observes pond water, blood samples and only living samples
- Describe the MRI(magnetic resonance image)
-
How it words: *Use short bursts of magnetic field
Uses:*Brain/spinal tissue images
*to see tears in soft tissue
*diagnosis of medical conditions - What is the deffinition of Life Science
- Life science is the study of living things. The main themes are: To see how orginisums grow and how they function, to find cures, combating disease, inherited diseases, and protecting the enviorment
- Describe the Scanning electron microscope
-
Magnification: up to 100,000x
How it works/description: *Electrons bounce off surface of the speicmen. * A 3D image is produced
Uses: *Provides clearer pictures of surface features (NONE living samples) - Which type of microscope would a scientist use if he or she wanted to look at LIVING organisms in a drop of pond water? (explain)
- A compound light microscope because it observes living samples such as pond water
- Describe the Computer
-
Year Invented:1946 (first electron computers)
Uses:* collections, storage, prginisums, and analysis of imformation
*Creating of graphs, solving complex mathematicle problems, share data/information with other scientist - List Some key words in the quiz
- Scientific method(all 6 steps), question, hypothesis, research, conclusion, data, observation, independent variable(goes on the x axis), dependent variable(goes on the y axis), control(s)
- Describe the CT scan(computed tomography)
-
How it works:*Low dosage x-ray beams pass through body at different angles(dye is injected to highlight tissues)
Uses:*Brian/spine tissue images
*Show body clots
*Diagnosis of medical conditions - Which of the tools(s) mentioned above provided the clerer images
- CT scans and MRI's
- Describe the X-ray
-
How it works: *Beams of electrons(radiation) are used to form an image
Uses: *Used to see internal industry analyst of chemicals (bones, heart, lungs)
*Used to learn about protein structure - Describe the Transmission electron microscope
-
Magnification:up to 200,000 x
How it works/description:*Tiny particles called electrons are used to produce magnified images
*A flat image is produced
Uses: *Porvides clear highly magnified images (NONE living things) -
