    Initially, I thought the dots on the rights looked bigger, because of the spaces between. I was surprised to learn I perceived such a fine difference. I when thought, “It’s a Trick” model and forces my intuition to choose the left organized array. For years, I have three jars, one huge 1 1/2 gallon plastic container filled with cotton balls, second about 300 ml plastic container filled with beans, and third a small glass jar filled with lead. I add weight to ensure each is equal on the scale. Kids’ sense of touch immediately lead kids to assume the tiny jar is much heavier. It’s a great way to prove we can’t trust our senses and need practice observing attributes and sometimes need measuring tools to help us.
