What do you notice? What do you wonder?

  1. How many little ketchup bottles will it take to fill up the large bottle?
  2. Too high estimate? Too low estimate?

Act 2

How much Ketchup is in each bottle?

Disclaimer: instead of using ketchup, colored water was used to make sure all the liquid was transferred from the large bottle to the smaller ones.

Special thanks to my friend Talia Cossin in Panama for sending me the 14oz glass bottle
