1. Tool and Technique Stations Instructions: Read the task card at each station carefully, and then do the activity. Reminder: Use our group procedures. You must work with your group; you will move through the stations together. Only one group may be at a station at a time. You may do the stations in any order. You do not have time to socialize with your group. Work seriously and responsibly through the stations. If you reach a point at which you cannot get to another station because they are all in use, you will need to wait quietly and watch until that station becomes available.

2. Length Station and calculation of volume

3. What’s important when using a ruler? Measure from the ZERO, not the edge of the ruler.

4. How can you find the volume of a box? Use a ruler to measure length, width, height.      Multiply l x w x h. How can you find volume of some irregularly-shaped solids? by displacement of liquid – (the difference)    

5. Volume Station—Graduated Cylinder

6. What is this? What is it for? What shape is it? Describe the markings. graduated cylinder measuring volume (in mL) cylindrical lines go up gradually from bottom to top

7. How do you use it? Read at BOTTOM of meniscus (curve). (You must move your head.) What’s different about these graduations? 

8. How can you find the volume of a box? Use a ruler to measure length, width, height.      Multiply l x w x h. How can you find volume of some irregularly-shaped solids? by displacement of liquid – (the difference)    

9. What’s important before measuring by displacement? Most objects should not be placed in a graduated cylinder. – Help me! I’m stuck!

10. Mass Station—Triple Beam Balance

11. What is this? What is it for? triple beam balance measuring mass (in grams)

12. How do you use it? --like Goldilocks Put all 3 riders at zero. Put object on the pan. PAPA—Start with Papa rider. Move Papa too far to right, then move it one back. MAMA—Do the same for the Mama rider. BABY—Slide the Baby rider until it is just right. Add the 3 measurements (Papa, Mama, Baby) together to get the mass in grams.

13. Visual Magnification Station L – Light Microscope

15. Visual Magnification Station D – Dissecting Microscope

17. Animal Behavior Station – Observation of a Live Organism

18. Journal Review Station Return to your table and complete a Peer Review form for last week’s journal. Do this for each person in your group.

19. How

23. You try it. Answer in your journal. No machine guns! A) What is the maximum mass that can be measured with this device? B) What is the minimum mass that can be measured accurately with this device? C) Mass (weigh) the objects provided: test tube clamp __________ 50 ml beaker __________ 250 ml beaker _____________
