In science we did two experiments. Our first experiment was on the force of
friction. Our second experiment was
called pennies part two. First we did an
experiment on hitting pennies. The
pennies went out of the stack sometimes.
It also fell down sometimes. It
was hard. I liked it.
Second we did the dirty penny experiment. We did coffee and vinegar to clean them. I think the coffee will work. I wonder what both of them ware like
together? I wonder which will work?

ReplyDeleteIt makes sense that the pennies on the stack fell because of the force of gravity. Its a really powerful physical force.
Which experiment did you like more? the first or the second experiment?
