**The Same Difference: the spread of rumors, catching the flu, and more math**

A research rotation for Southwestern's "Science Training and Education Program" or

STEPS

Description that the students saw to decide between session offerings:

What do gossip and disease have in common?
Come and learn the mathematics that describes them both.
We will use the computer to virtually spread disease or rumors,
perform computations, and create graphs.
No previous computer skills are needed.
Students will present our simulations and their meaning.

Each research rotation will meet in a small computer lab, MBH 118.

ROTATION 3: Sarah Cudzilo Mon Jun 17, 12:45pm-3, 3:30-4:45pm

- Students set up rules and expectations.
- Intro to Excel: save a file; copy, paste; relative addressing; entering a formula; dragging to create an arithmetic sequence.
- File hierarchy on the USB drives. Safely remove USB drive.
- Code a multiplication table in Excel with an appropriately addressed formula.

Included PasteSpecial/Transpose from column headers to row headers. - Notes in a Word document on types of Excel addressing.
- Code values of a linear function by referencing a slope and an intercept and x-values. Create a graph. Copy and paste the table and graph into Word, leaving blank lines to allow greater editing control and ease.
- Simulation of disease spread within a group of 6 names by rolling a die.

Excel graph.

- Write up the instructions for our procedure from last time.
- Discuss simulation of disease spread within a small group by selecting names on paper.

CopyAndPasteSheet; insert columns and see how the graph changes. - Perform another simulation with 6 people and dice.
- Write up the simulation of CONTACT. S-I model.
- Discuss and write up the SHAPE of the graph!!
