1. How We Study Science
Tools/ Equipment

2. 1. Compound microscope- see worksheet
Microscope slide Cover slip
Glass slides are used for viewing items under a microscope and/or on which you place substances for closer study.

4. Fill in the table on your worksheet.
What’s my power?
To calculate the power of magnification, multiply the power of the ocular lens by the power of the objective.
What are the powers of magnification for each of the objectives we have on our microscopes?
Fill in the table on your worksheet.

5. Comparing Powers of Magnification
We can see better details with higher the powers of magnification, but we cannot see as much of the image.
Which of these images would be viewed at a higher power of magnification?

8. Triple Beam Balance
Used to find the mass of an object

9. Graduated cylinder
Used to make accurate measurements of volumes.

10. Medicine Dropper/Eye dropper
Used to move small amounts of liquid. Many droppers have measurement lines for exact measurement of liquids.

11. Beaker
Beaker
Beakers are the most versatile glassware in the lab and can be used for just about anything. The volume graduations on beakers should be used only for "ballpark" estimates.

12. Rubber stopper

13. Funnel
When lined with filter paper, used to filter suspended solids from a liquid. Used to move liquids from a large receptacle into a smaller one.

14. Test Tube
Used for heating solutions and for performing ordinary reactions.
