Unit Conversions: Convert the following measurements into the units asked in each question.
7. 2 kilometers
=
200,000 centimeters
8. 132 dekaliters
=
13200 deciliters
9. 670 grams
=
.67 kilograms
10. 900 hectometers
=
90,000 meters
11. 79 decigrams
=
7,900 milligrams
12. 55 liters
=
.55 hectoliters
13. 9,320 g
=
932 dekagrams
14. 74,000 mm
=
0.74 hectometer
15. 4400 milliliters
=
16. 123 dekameters
=
0.44 dekaliters (give the unit)
12,300 decimeters (give the unit)
Lab Tools:
17. How is a centimeter ruler different from a millimeter ruler?
Centimeters have a decimal in the answer and the millimeters are a whole number.
18.
8.3 cm 83 mm
19.
5.8 cm 58 mm
20. When reading a graduated cylinder, the scientists should be at eye level and should read the
meniscus (bottom of the bubble).
21. Describe how to find the volume of an irregular shaped object. What are the units?
Volume displacement – fill a graduated cylinder to 50mL; place object in graduated cylinder
subtract the volume from 50 mL.
units: mL
22. Describe how to find the volume of a regular shaped object. What are the units?
Use a ruler to measure the length, width, and height. Volume = L * W * H
units: cm3

Lab Reports:
23. Give a brief description of each of the parts of a lab report listed below:
Title Page: Introductory page
Purpose: Where the problem is identified and what you are attempting to discover
Background Information: Location where key terms and materials are identified
Procedure: A description of brief steps of the experiment
Hypothesis: An if then statement of the expected outcome
Data Collection and Observations: Where results and comments are recorded from the
experiment
Discussion/Conclusion: Displays graphs and final results
Graphing and Slope:
24. When should you use a bar, line, or pie graph?
Bar compares data
Line shows a change over time or distance and an overall trend
Pie shows part of a whole or percent.
25. What variable goes on the x and y axis?
X axis – Independent Variable (picked)
Y axis – Dependent Variable (measured)
26. How can you determine if your graph has a good scale or displays the data well?
The data should take up more than 50% of the graph area on the x and y axis. Fold the paper in
half width-wise and length-wise – can you see data on both sides?
27. Describe how to find the slope of a best fit line using the formula for slope.
Pick two points on the best fit line (x1, y1) and (x2, y2) and plug into the formula below:
m=
y2 – y1
x2 – x1
28. What are the only conditions that will allow you to find the slope of a line using a graph and
rise/run?
You can only use rise/run if the increments for the x and y axes are 1!

30. What is the density of an object with a mass of 5g and it takes up 10 mL of space? D=m/v
= 5 / 10 = 0.5 g/mL
31. What is the relationship between temperature and density? What type of motion does this
cause?
As temperature increases, density decreases and causes a lifting or rising motion.
32. Cold water sinks because it is (more/less) dense.
33. Complete the diagram of a convection cell below by labeling where the following characteristics
would be found:
a.
