- Mindful moment. “Every time we become aware of a thought, as opposed to being lost in a thought, we experience that opening of the mind.”

- * * * * *
You may spend this class period composing the report on your Tumble Buggy investigation. Follow the following format and guidelines. Ask for help if you need it. This report is due in hard copy and digital copy in your DSN at the beginning of class on 21 September.
- Title – Clearly stating what the experiment is about
- Background – What have you learned about motion before this assessment project? Describe experiences and new knowledge. Mention learning about how to measure motion, how to analyze data
- Question (expressed in a clear form)
- Expected answer – (before doing the experiment) and why you expected that answer to the question?
- Methods or Procedures (written in 1st/3rd person and past tense; not written as commands)
- How was data acquired
Remember that you have two sub-questions. One is about the speed. The other is about the direction. You have different procedures for each question.
2. How was data analyzed (graphs and calculations)
- Table of results (organized and labeled)
- Calculations with correct units.
- Appropriate, well-made graphs
- Anecdotal observations.
- Analysis or Interpretation
Relate results to question. How do your results relate to what you expected? Use evidence from your data to support claim of what the speed of the Tumble Buggy is and whether it is constant. Use evidence to support claim about how straight the direction of travel is. Refer to scientific concepts relevant to the problems that we have discussed in class. Discuss the size of any variation in results and factors contributing to it.
- Conclusion Summary and New Questions
Summarize results, suggest new questions and propose new experiments to investigate the tumble buggy and its velocity (speed and direction), motion, and performance.
Meeting—Includes details of practice and reasoning. Makes accurate measurements. Constructs correct graphs and makes correct calculations (including units). Demonstrates understanding of techniques for acquiring and analyzing data relevant to motion. Demonstrates understanding of the concept of average speed.
