1. Does the cat eat more when the tv is on or off?
BELL WORK: Answer only
My cat Kainoa is a picky eater. I’ve noticed that he eats better when the TV is on. To test this, I set out 0.25 kilograms of food and left the TV on for 4 hours. I measured how much food was left. There was .05 kg of food left on Day 1 and .08 kg on Day 2. The next day, I set out kilograms of food and left the TV off for 4 hours. I measured the amount of food left. After Day 1, there were 0.08 kilograms of food left and after Day 2; there were 0.12 kilograms of food left.
