7. Assignment Title: Scientific Instruments This entire handout is worth 20 points. The first ½ of the front page is a direction instruction. The rest of the handout (including the back), you will complete on your own. The assignment is due TOMORROW at the BEGINNING of class. If you finish it TODAY in class, you don’t have HW tonight.

8. Name: Triple Beam Balance Purpose: Find mass --------------------------------------------------------------------- Name: Ruler (meterstick) Purpose: Find length ---------------------------------------------------------------------- Name: Stopwatch Purpose: Find time

11. Name: Graduated Cylinder Purpose: Find volume Key Term: Meniscus

12. * Meniscus = the little dip in the liquid level

14. IP: The rest of the worksheet STATIONS -Let’s read the directions together. -RULES: -There are multiple instruments at each station. Use them as I showed you in class. -There are more people than stations. If Station 1 is crazy crowded, go to another station or answer the review questions first. -BE RESPECTFUL.

15. IP: The rest of the worksheet DUE TOMORROW. – Finished? Place it in the box. – Not finished? Finish up for homework! Place it in the box as you walk in tomorrow.
