A Word About Safety… make sure you work with field of science! “Isn’t Chemistry someone experienced when Dangerous?” A lot of folks you’re working with new stuff get nervous around you’re unsure about. Just chemistry. You can’t always use common sense—If it ‘see’ what’s going on (are seems like it could be there toxic gases generated dangerous, ask for help. from that reaction?). Let’s get started! Put on Unfortunately, a lot of people your safety goggles and have made the generalization gloves (yes, those are that chemicals are dangerous REQUIRED) and let’s go! and their effects are bad.

Which has more to hang out together in groups. humans and some vitamin C: cooked primates have this ability - spinach or raw? These groups of atoms are called plants and most other molecules. A molecule can be made of animals do not. anywhere from two atoms to millions of atoms. Together these atoms make absolutely everything. So if hydrogen and oxygen are two kinds of atoms, then a molecule is when hydrogen and water atoms combine to make water. Water is the molecule. All matter is made of atoms. Shoes, air, watermelons, milk, wombats, you, everything is made of atoms. Hundreds, and billions, and zillions of atoms make up everything. When you fly your kite, it’s the air atoms (nitrogen and oxygen mostly) moving against the kite that keep it up. When you float in a boat, it’s water atoms (hydrogen and oxygen) under your boat holding it up. 6 Supercharged Science SuperchargedScience.com SSUPERCOOLINGUPERCOOLING LLIQUIDSIQUIDS Activity Experiment #1: What’s Going On?
