3. COLLEGE-STYLE LAB REPORT
Title: State a title for the lab.
Problem: State the problem (as a question)
Materials: State the equipment used.
Hypothesis: State an educated guess that answers the problem.
Vocabulary: Define: potential energy (& formula), kinetic energy (& formula)
Procedure: Steps taken to complete lab
Experimentation: plotting data, graphing; prediction (extrapolation); graphic relationship [inverse?, direct?, cyclic?, static?] (see worksheet)
Questions: see worksheet (front & back)
Conclusion: Is hypothesis true or false?
Explain what you found by experimentation (graphing).

4. Ramp Height vs. Distance Moved Graphx *
More Height, More Weight
Less Height, Less Weight 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1
Distance cup moved (cm)
Ramp Height (cm)

5. DENSITY ACTIVITY Mass = balance (g); nearest tenth 1.0, 1.5
Volume (cube) = L x W x H; cm3 or mL
Density = mass g
volume cm3 M V D
Use centimeters (cm) only
less
Height (thickness)
Width
Water = 1 g
cm3
greater
Length

6. DENSITY = g/cm3

7. Density Problem on State Test
If an object is cut in half, quarters, thirds,
does the density change? Why? Explain yourself.
Density does not change. Density will stay the same because if object is cut up into pieces . . .
Density represents the internal arrangement of the atoms in the object.
Density does not change because mass and volume change proportionately.
