This worksheet is a template for recording what you see when you look at things under a microscope. Since there are no specific questions or data provided to solve, I will explain how to fill it out correctly so you can use it for your science class.
How to Fill Out the Worksheet
1. The Circles (Drawings)
*
What to do: Inside each circle, draw exactly what you see through the microscope lens.
*
Tip: Try to keep your drawing proportional. If the cell looks round in the microscope, draw it round. If it looks like a rectangle, draw it like a rectangle. Do not add things that aren't there!
2. Magnification
*
What to do: Write down the total power of the microscope for that specific drawing.
*
How to calculate it: Multiply the power of the eyepiece (the part you look through) by the power of the objective lens (the part close to the slide).
* *Example:* If the eyepiece is
10x and the objective lens is
40x, the total magnification is
400x.
3. Description
*
What to do: Use the lines to write notes about what you observed.
*
What to include:
*
Shape: Is it circular, square, irregular?
*
Color: Did you use a stain? What color did it turn?
*
Parts: Can you see the nucleus (the center dot), the cell wall, or vacuoles?
*
Movement: If you looked at pond water, were the little creatures moving? How fast?
Example Entry
If you were looking at an onion skin cell, one box might look like this:
*
Drawing: A row of brick-like rectangles.
*
Magnification: 100x
*
Description: The cells look like bricks stacked together. They have thick borders (cell walls). I can see a small dark dot inside each one (nucleus). They are stained purple.
Final Answer: This is a blank observation sheet. To complete it, draw your specimen in the circles, calculate the total magnification (Eyepiece × Objective Lens), and write details about the shape, color, and parts of the specimen in the description lines.
Parent Tip: Review the logic above to help your child master the concept of microscope observation worksheet.
