SWIRL!
• Different sizes.
• Ex. 500ml Erlenmeyer Flask

4. Graduated Cylinder
• Function - To accurately measure liquids.
• Different sizes.
• Ex. 10ml Graduated Cylinder.

5. Test Tube
• many functions including mixing liquids to
observe their reaction.

6. Dissecting Kit
• Used for dissection.
• Contains: Scalpel, Forceps, Probes, Dissecting
Scissors, and Metric Ruler.

7. Scalpel
– Function - To cut open a specimen you will be
dissecting.

8. Forceps
• Function - To hold and move parts you should
not touch, or are too tiny for your fingers.

9. Probes
• Function - To move and push aside materials
during a dissection.
• A dissecting kit contains a straight probe and a
bent probe.

10. Dissecting Scissors
• Function - To cut specimen you are dissecting.
• Often used to cut through small bones.
• Often work better than scalpel.

11. Metric Ruler
• Function - To measure the length of small
objects in centimeters or millimeters.

12. Dissecting Tray
• Function - Provides a place to dissect your
specimen and a surface to stick dissecting pins
into.

13. Dissecting Pins
• Function - To hold a specimen down to the
dissecting tray.

14. Petri Dish
• Function - Provides a surface for you to
experiment on various materials. In our class
we will use them to grow bacteria and fungi.

15. Triple-Beam Balance
• Function - To measure the mass of an object
in grams.

16. Meterstick
• Function - To measure the length of objects in
centimeters or meters.
