Atoms, Electrons, Protons, and Neutrons

Atoms, Electrons, Protons, and Neutrons
Atoms are everywhere. You’re made of atoms. Your dog is made of atoms. Your peanut butter sandwich? Yep. Made of atoms. Atoms are the smallest particle of matter. They’re so small that they can’t be cut, or divided. Molecules are made up of atoms. Confused? Think of a sentence. The words...

Chemical Composition

Chemical Composition
Chemical composition has more than one meaning. If you’re discussing a substance with one component, such as water, the chemical composition means the type and arrangement of elements and molecules within the substance. If you’re discussing a substance with more than one component,...

Gases

Gases
You know that water is a liquid, ice is a solid, and steam is a gas. But what exactly is a gas? The molecules in a solid are stable. They don’t move and they’re packed closely together. The molecules in a liquid are spaced farther apart. But the molecules in a gas are active. They move...

Chemistry Safety

Chemistry Safety
The inventor, Thomas Edison, loved learning and experimenting. His mother taught him at home and let him create a chemistry lab in the basement. As a young teenager, Edison got a job working on a train. He was kicked off the train after one of his science experiments set a train car on fire. The...

Weights and Measurements

Weights and Measurements
Let’s say you wanted to tell a friend how large your dog was. You had never heard of inches or feet. How could you explain it? Thousands of years ago, people used common objects to describe and compare measurements. You could use your hand as a measuring tool, i.e., “My dog is 8 hands...

Solutions and Mixtures

Solutions and Mixtures
Have you ever mixed things in the kitchen just to see what you could make? Maybe you sprinkled some cinnamon or salt in a cup of water or poured in a splash of vinegar or oil. Maybe you called it a potion, but you were also making a solution or a mixture. You were being a...

Styrofoam Polymers

Styrofoam Polymers
Chances are, you use Styrofoam almost daily. Those fold-and-seal take out boxes are made from Styrofoam. So are the thick white cups used to keep your hot cocoa warm. How about those wedges of plastic you find in packing boxes? Styrofoam keeps computers, electronics, and other fragile items safe...

Monomers, Polymers, and Plastic

Monomers, Polymers, and Plastic
All plastics contain polymers, but not all polymers are plastic. Confused yet? Let’s break this down. Monomer means “one,” and monomers are small molecules containing one part. These molecules can join with other...

Acids and Bases

Acids and Bases
Let’s head to your kitchen. Taste a bit of lemon juice or vinegar. Did you pucker? Now taste a tiny fleck of baking soda. It’s bitter, right? Lemon juice and vinegar are acidic, while baking soda is alkaline, or a base. Almost every liquid is either an acid or a base. Chemists know that...

What is Matter?

What is Matter?
Matter is all around you. Your bed, your dog, even the air you breathe, are all made of matter. Matter is anything that takes up space, including gases and liquids. Matter takes on different forms, known as the states of matter. You probably already know about solids, gases and liquids,...

Chemistry: What Is It?

Chemistry: What Is It?
Chemistry is the scientific study of matter. Remember, matter is any substance – liquid, gas, or solid. Chemists study the composition of matter – what it’s made of – and how it interacts with energy and other substances. By studying chemistry, scientists can develop new products,...

Elements

Elements
We know that all matter contains atoms, and those atoms contain protons, neutrons, and electrons. But atoms aren’t all the same. They have different amounts of protons, neutrons, and electrons. Scientists have discovered about 120 different types of atoms – or
