Count your drrips!
Take a gwess - How mnny drops af water
will it take to equal I milliliter?
drops
Follow the directions to find the nurnber of drops in 1 millililer of water, then answer the questions. You
will need a small graduated cyiinder (25 ml), a beaker of water, and an eyedropper for this section.
(1) Fill a small graduated cylinder with 10 ml of water
(2) Count the number of drops it takes to raise the water to 11 rni. Record &e number in the chart.
ig) L"ure the water in the griduated cylinder and count the number of drops it takes to raise the water to 12
ml. Record the number in the chart.
{4)l-eave the water in the graduated cyiinder and count the number of drops it takes to raise the water to 13

Zero yourbalance.
Find the mass of the small rock. Make sure that you are as accurate as possible. lf you are
not sure about how to find the mass or zero your balance, ask the teacher. Record this
mass in the data table.
Now, zero the balance again or move all of the masses to 0, remove the small rock and
now find the mass of the large rock. Record this mass in the data table.
Repeat steps 1-3 four more times, recording yow data as you go. Be sure to alternate the
small rock and then the large.
Find the mass of the small rock 5 times in a row, zeroing your scale between each
measurement. Record these measurements in the data tabie.
Now, find the mass of the large rock 5 times in a row, zeroing your scale between each
measurement. Record these measurements in the data tabie.

What did you notice about the mass of the large rock when you didn't alternate it?
Is the balance more precise for large or small objects? That is, were the measurements
more consistent for the small rocks or the larger rocks?
When is your balance going to be the most precise?
Make a bar graph of the differences between each rock type and measurement type to
illustrate when the scaie is the most accurate and when it is not.
What does precision mean?
Conclusion: (Was your hypothesis right? What did you like about this lab? What are two things
that you leamed &om this lab? Which method was the easiest to use? Which was the hardest?)
