Fall 2016: Day 3

9:30-10:00 Exploring Light and Shadow Phenomena III
Small groups generate a question about the moon to explore
Go on a field trip to sidewalk if sunny to ‘observe’ the sun
Bring sky journals, observe moon is not visible
also bring pinhole envelopes, meter sticks, pencils to record diameter of the Sun’s projection;
(If not sunny, use lamps without shades inside, but do review first)
10:00-10:10 Reviewing resources, powerful ideas about light, ray diagrams, and scientific explanations (Emily) 10:10-10:45 Using mathematics to estimate a quantity of interest:
If sunny: how big is the sun?
If not sunny: how represent pinhole phenomena mathematically?
(inside with light bulb, movable pinholes, wax screens:
After develop pinhole formula, then pass out sun projections from earlier classes and use to estimate how big is the sun?)
10:45-11:05 Reporting Findings
11:05-11:15 Writing
11:15-11:20 Answering questions about course
11:20-11:25 Checking off laboratory notes
11:25-11:50 Reflecting
