| Unit 2.1 | Making Things Bigger. |
| Q1) Why do small things need to be magnified? | So they become visible to us. |
| Q2) What are objects that can only be seen by a microscopic called? | Microscopic |
| Q3) What type of microscope is used at many science laboratories? | A Light Microscope |
| Q4) What is unique about a monocular microscope? | It only has one eyepiece or ocular lense |
| Q5) What is a stereo microscope? | A binocular microscope that you see in three dimensions. |
| Q6) How is an image created? | Light shines onto the specimen and is then reflected back up through the lens to create and image. |
| Q7) What is the objective lens? | The lens of the microscope closest to the stage |
| Q8) Why is the stereo microscope also called the dissecting microscope? | Because it is often used to examine and dissect small plants and animals. |

| Q15) How far can electronic micrsocpes magnify up to? | A Million Times |
| Q16) Why are objects observed by microscope measured in very small units | Because they are even smaller than a full stop. |
