I got lazy this week so ran my daughter’s plastic (I know) reusable water bottle through the dishwater. It did not survive the experience. (I know.) But it did make for a fabulous opportunity to do a little science (and math — ssh!). Join my daughter and I as we figure out why our plastic water bottle melted in the dishwasher, and by how much.
Looks like my daughter’s been reading Blockhead: The Life of Fibonacci again. Related Links: Book Review: Blockhead by Joseph D’Agnese (Caterpickles)
While we were at lunch last week, The Ten-Year-Old’s mind turned to fractions, as fifth grade minds are prone to do.

That tennis post I did last week keeps generating questions. One reader noted that it seemed weird that the 6 sets in medieval tennis contained only 4 60-degree games each, especially if tennis scores were meant to represent the 360 degrees in a circle. Mathematically speaking, it would make more sense to have each set contain 6 games. Which raised the question, why 4? Was the number 4 significant in some way for medieval tennis players?
Our mostly-weekly survey of the tidbits that cross The Eight-Year-Old’s desk. This week, The Eight-Year-Old does math with cats and discovers a new-to-her-book buried under her Elvis wig.
The Eight-Year-Old wandered into the kitchen the other day while I was prepping a blueberry and spinach smoothie. While watching me stuff the blender with spinach and almond milk, she asked, “Mommyo, if you ate only spinach, how much spinach would you have to eat to maintain your weight?”
