## 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.

## 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.

## Musings ...

It's fairly well-known how to find the height of a tree on a sunny day. Can we use something similar here?
