Did you know first graders have superpowers? Not just the things we talked about yesterday (friendship and kindness) but for real superpowers. Check out the picture below. We can fly, lift buildings and cars, see through walls, become invisible, and run at lightning speed!!
And...we heard from Mr. Yari, our Scientist of the Week. He asked us: What will happen if I pierce a plastic bag full of water with a sharp pencil? We made some great hypotheses (including exploding water), but turns out he had a surprise for us. Ziplock bags are made of polymers. Polymers are chains of flexible molecules. When broken by a sharp pencil they form a seal that is water tight! Check out how many pencils we fit through this bag without any leaks!! Thanks Yari!
