Rolling Ball Lab Activity
Mr. Logan's List of Instructions
Mr. Logan's Checklist For Self-Evaluation
Great Falls Public Schools Foundations Of Science Process Skills (As Used In Mr. Logan's Class)
| 1. Write a detailed procedure of how you solved the problem. Write the procedure so |
| another student could follow your directions and get your data and your results. |
| 2. Create a detailed Data Table that contains all given, collected and calculated data. |
| 3. Draw two bar graphs. One comparing the velocities of each ball and one comparing |
| the momentum of each ball. |
| 4. Create a raw data sheet that neatly shows all of your collected and recollected data and all of the calculations. (5 step format) |
| 5. Use the rubric, on the back of this page, to create a complete lab write-up. |
|
* |
Restate
and answer the following questions in your report
1.
List and explain 5 reasons Mr. Logan had you do this lab. 2.
Did all of the balls have the same velocity?
Compare each ball and explain why. 3.
Did all of the balls have the same momentum?
Compare each ball and explain why. 4.
How did the size affect the velocity of the balls?
Explain and give evidence. 5.
How
did the size affect the momentum of the balls?
Explain and give evidence. 6.
How
did the mass affect the velocity of the balls?
Explain and give evidence. 7.
How
did the mass affect the momentum of the balls?
Explain and give evidence. |

|
Observing and Questioning Adding
to the knowledge base by creating meaning from experience. |
Restates
the prompt or problem. OR Writes
question that is not testable. |
Writes
questions that are testable and based on observations and prior
knowledge. |
Writes
questions that are testable and based on observations and prior
knowledge. ·
Observations
and questions are detailed, relevant, and concise. |
|
Predicting and
Using Variables Uses
evidence and controls variables in order to verify or refute ideas. |
Hypothesis
is not written in the “if...then…because” format |
When
prompted, generates a testable hypothesis (if…then… because format)
that uses dependent, independent, and controlled variables to gather
evidence of support or nonsupport. |
Hypothesis
is detailed, relevant, and logical. |
|
Communicating Information Oral,
written or mathematical process of describing an event, action or object
to and/or with others. |
Not
detailed enough to be replicated. Nonsequential Data
table(s), graph(s) and/or diagram(s) are not labeled or labeled
incorrectly. |
·
Describe
how to conduct an experiment that can be replicated ·
Information
is presented in a logical and sequential manner in such a way that the
reader should need no assistance with its interpretation. |
Information
is effectively communicated by being: ·
Detailed ·
Relevant ·
Accurate
& precise ·
Supported
by evidence |
|
Organizing Organizes
ideas using text, graphs, and or other visual and mathematical
representations. |
|||
|
Measuring Determining
qualitative and quantitative properties of objects and changes during
events. |
·
When
prompted, selects appropriate instruments for measuring properties of an
object. |
·
Independently
selects the most appropriate instruments for measuring properties of an
object |
·
Reports
measurements with appropriate numbers of significant digits. |
|
Data Analysis (Making Sense of Data) Making
objective statements that reflect information and/or data. |
Makes
no inferences in the analysis. |
·
Correctly
construct and label tables, graphs and diagrams ·
When appropriate apply mathematical strategies to
the data ·
Identify trends and patterns in data |
Identify
mathematical relationships between variables. |
|
Inferring Creating
explanations based upon previous experiences and observations. |
Conclusions
are not supported by data. Errors
are not identified. |
·
Conclusions
are based on a careful analysis of data ·
Identify
errors and limitations and their effects on results. |
·
Suggests
improvements in experimental design AND/OR ·
Explain
conceptual and physical models (Relates
results of investigations to real-world experiences
further investigation.) |
