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)

Mr. Logan's List Of Instructions

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.

*

Use this Checklist to make sure your report is complete.

Before you hand in your lab write-up go through the checklist looking for omissions.

Process Skill  and Definition

Not Proficient

Proficient

Advanced

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.)
