My son (Z, who is 3 years old), got a little flashlight as a birthday party favor. “Look, Mama! Little!”
“Cool! Can you make the light big?”
“Neat! Can you make it little again?” Z repeated this a few times before getting bored. The next day, he asked for the flashlight again. I suggested something new. “Can you make a small light on the wall?”
“Yup, that works. Can you make a big light on the ceiling?” He was pretty good about appeasing me. I tried to get him to say what exactly he was doing along with his actions, but wasn’t successful. Producing a small light on the ceiling just made him giggle.
Doing science doesn’t have to be complicated, with the whole scientific method and so on. Try something, and try something else. And then try a variation or two. Adam Savage says:
Guess I’ll do the writing for Z for a little while.
