We made "army ant" centimeter rulers and learned about the adaptations of these 1 cm ants. (These rulers are in contrast to our "inch worm" rulers.) We estimated lengths in centimeters and then measured with our metric rulers. Many children made connections to the metric system from driving in Canada to seeing liters of soda in stores. We researched the metric system and found out that 2 other countries in the world in addition to the USA do not use the metric system: Myanmar and Liberia.
Our final project was to estimate and find out how long 14 meters is. That is the length of a colony of army ants on the move to a new eating area. We found out that in some parts of the world families leave their doors open for the army ants because once the ants pass through, all of the other pesky bugs in the house will have been eaten!
