Spot The Pot ... This page is to discuss the first part of the activity. !! The Setup At one end of the room put a single table with a small pot on it. Across the middle of the room put a row of tables. On one table put a "spot". This can be a piece of paper taped down on the table with a big black spot on it, or whatever. | | |>> Table with pot <<| | | | | | | | | | | | ---- | Barrier across room | ---- | | | |>> Table with spot <<| | | | | | | | | |>> Students <<| | | !! The Challenge Without crossing the row of tables, find the distance from the spot to the pot. You can use anything you would typically find in a house. Things like string, pencil, paper, ruler, tape measure, etc. What you can't use are things like theodolites, sextants, or other exotic devices. The exercise is perfectly possible with a ruler, some string, paper, pencil, and a calculator. With care, the calculator isn't necessary. ---- !! Ideas ... Before giving a "solution" I'd like to invite people to suggest ideas for solving this challenge. Edit this page to add your comments and ideas. ---- !! Musings ... It's fairly well-known how to find the height of a tree on a sunny day. * See How High Is That Tree? Can we use something similar here? ---- An enrichment activity
