Introduction to Microscopes: Cut and Paste Paper Microscope Model
For my students the "Science Works" Microscope Model opens up a whole new world. It can be pure entertainment in and of itself to build the microscope.
Knowing how to use the microscope properly and being able to get excellent resolution is crucial for students to see this microscopic new world. In this "Science Works" lesson, students will have fun creating a color coded microscope model made from paper while learning the structure and function of its parts.
a. Cut out microscope parts handout with color-coded key
b. Student structure and function notes chart with key
c. Practice microscope quiz with parts lettered
d. Teacher sample of completed model project
1. I like to start out with a discussion about what students can see with a microscope. Show real life examples. I use a combination of Youtube videos showing fantastic microscope clips. This gets students interest in thinking "small". You can also just use cool pictures projected to get the discussion started.
2. Next we go over the actual microscope, filling in the structure and function chart together. Students have an unplugged microscope on their desks to follow along. I have them point to the parts and write down the function while they explore it on a real microscope.
3. After this, students color their microscope parts in and fill in the color coded key. I give each student a piece of light colored construction paper and they glue the scope back together with the key.
4. At this time, it is a good idea to explain how a microscopic field of view works and how to view specimens under increasing power. If you look on the teacher's sample included you will see the field of view diagram I use to explain this. It is fun to use the example of viewing an ant.
5. Finally we use the practice quiz paper included to check for understanding. Students can partner up to practice quizzing each other using the chart. It can also be an open or closer the next day.
6. I like to close with a Quick write or exit ticket:
a. How do you think the microscope changed the history of the world forever?
b. What would you like to look at under microscopic power next?
I love teaching biology using a microscope because it's a delight to hear students squealing, "Mrs.Goit, come look at this!".
