Collected Sun Lab Reports

Wrote up new Lab description with everything in correct order but most students did not need it.

Went over Textbook Scavenger Hunt:
1. Roemer and speed of light
2. Black hole box - singularities (North Pole)
3. Number of Earths that span Sun, number of Suns that span the Earth-Sun distance, definition of meter to get scale of Earth
4. Graphs - make line graphs to find relationships between variables. Best graph is a straight line through the origin because then the mathematical relationship is y = mx
Showed how to deal with units of slope and area for velocity vs time graph.
5. Exponential gain - derived equation
6. Forgot to show butterfly effect - do that tomorrow
7. Express to impress - relative sizes of nucleus and hydrogen atom
8. Definitions - work
9. Can't see atoms in visible light - probing device is too large.
10. Fermi number calculation
11. Density - sink or swim
12. Demo with hot/room/cold water

Santa Poem
Thumbs up for Santa, Right
Fingers curl, spin day to night
These same fingers also show
The way around the Sun we go

HW - Tell parents about 1 or 2 things we discussed today.
