Marble and Ramp Video Lab
Goals and Background
- Students should understand the difference between science and engineering:
-
Science poses questions about the natural world and answers in the form of evidence-based explanations.
- Our question or inquiry: How does the marble GPE affect the KE in the marble / ramp system?
-
Engineering identifies problems and proposes solutions.
- Our science question leads to practical engineering problems:
- Measuring and changing GPE
- Measuring KE
- Our science question leads to practical engineering problems:
-
Science poses questions about the natural world and answers in the form of evidence-based explanations.
- This activity addresses these 'I can" standards:
Communication
Our Inquiry and results will be communicated using the standard OHSD lab report format with an Engineering section added.

| Question | How does the marble GPE affect the KE in the marble / ramp ? | ||
| Background | What do you already know about this experiment? | ||
| Hypothesis |
What do you expect the answer is for the question? "If (mv), then (rv) because (reason)." |
||
| Materials | · V-shaped plastic channel · marbles ·books · masking tape · ______ | ||
| Procedure |
Do you have a step that tells a person what to change? (mv) | ||
| Do you have a step that tells a person what to measure (rv) after they make the change you described above? | |||
| Do you have a step that tells a person what to always keep the same? (controlled variables) | |||
| Do you have a step that tells a person to write down the data? | |||
| Do you have a step that tells a person how many times to do these steps over? (repeated trials) | |||
| Check your procedure...does it make sense? Could anybody use this procedure to do the experiment? | |||
| Data | Does your data table include what you changed (mv) and what then happened (rv) ? | ||
| Sample calculations showing how GPE and KE were found | |||
| Conclusion | Did you restate your hypothesis? | ||
| So tell me, was the hypothesis or prediction correct? | |||
| When you changed your variable (mv) the least, what happened (rv)? | |||
| When you changed your variable (mv) the most, what happened (rv)? | |||
| Put it together for me, what does the data say about your hypothesis? | |||
| Measuring and changing GPE | Our solution | ||
| A strength of our solution | |||
| A weakness of our solution | |||
| Measuring KE | Our solution | ||
