- 1Making Things Bigger: Using Microscopes
- 21. What does 'magnified' mean?Being made bigger.
- 32. What is a microscope and how does it help scientists?An instrument used to make very tiny things look bigger. It's useful when scientists need to zoom into very small specimens.
- 43. What is a specimen?The object being looked at through the microscope.
- 54. What is a light microscope?A microscope that uses light to reveal the image.
- 65. What is an image (in scientific terms)?What is seen through the microscope.
- 76. What is the difference between a LIGHT microscope and a BINOCULAR microscope?LIGHT MICROSCOPE: has one ocular lens
BINOCULAR MICROSCOPE: has 2 ocular lens - 87. What are the different parts of the microscope and what do they do?
- 9Eyepiece and Objective LensMagnifies the image
- 10StageWhere the specimen is placed
- 11Mirror/LampDirects light up through the stage and specimen
- 12HandleFor carrying the microscope
- 13Fine Focus Knob and Course Focus KnobFine Focus: used to focus the image on high power
Course Focus: used to focus the image on lower power
- 148. What is a Stereo Microscope?A binocular microscope that creates a 3D image
- 159. What is a dissection?To cut apart a dead plant or animal to study it
- 1610. What is magnification?The amount by which the image is magnified compared to the real object (specimen)
- 1711. What is a micrometre?1000th of a millimeter or one millionth of a metre. Used for measuring very tiny objects as millimetres might be too big.
- 1812. What is an electron microscope and what is it used for?A microscope that uses beams of electrons to magnify up to 1 million times.
Its used for higher magnification.
- 1913. What are the 2 types of electron microscopes and what do they stand for?SEM: Scanning Electron Microscopes
TEM: Transmission Electron Microscopes - 2014. Comparing TEM and SEM microscopes...
