Your task: Analyze the data from your Hanging Balloon Experiment and your Hanging Charge Simulation You will compare your balloon data with the idealized simulated data to describe the relationship between FE and r and determine where there could be sources of error.

Your screencast should:

Be less than 2 minutes long at a regular speaking pace (do not speed up your recording).

I will stop watching at 2min. This requires you to determine what the most important information is and convey it efficiently.

Picture you throughout (webcam on)

Visual Part that goes on slides you make to communicate the concepts

Include Free Body Diagrams of your scenarios to illustrate how you began your calculations

Include graphs of your data after linearization (If/when linearization is necessary).

In the case of your balloon, you may have attempted three versions of linearization to test for proportionality.

Graphs should have all appropriate parts, including correct units, titles, best fit line for the linearized version. (use your checklist)

Explain how you adjusted units appropriately

Calculate the FE according to your data

What you talk about (you'll want some carefully crafted bullet points to support what you're saying)

Explain the trends in your graphs. (Use your Interpreting Graphs page)

Explain how you used the free body diagrams to calculate FE.

Discuss sources of error in your balloon experiment and how the simulation helped you realize they were errors:

any way in which your data differed from the pattern of data in the simulation,

what random or systematic errors occurred during the data collection, and how you knew they were influencing your data. Specifically how did the errors impact your data (were your numbers too high, too low, randomly inaccurate?

how to reduce the errors if you had the time and resources to repeat this experiment

Though you may be good at the mechanics of your work, it's still important to be able to communicate it well. The criteria above point to your ability to carry out certain scientific processes, but the criteria below convey your ability to communicate that work effectively. These criteria must be met in order to earn full credit.

Strong screencasts:

Limit the number of bullets and text on slides. (Put enough information there to talk about, but not everything you want to say)

Interact with the carefully chosen text and images on the screen as you explain verbally.

Avoid reading off a script, but explain from memory (For the love of all things, scripts are super boring. Make talking points for yourself and speak naturally)

Are engaging
