Cotton is a plant product used to make fabric. Cotton is made of cellulose, a fiber not digestible by humans. Cellulose is composed of many sugar molecules bonded together into long chains. Each sugar molecule contains carbon, hydrogen, and oxygen atoms. When cotton fabric is washed, wrinkles often form. The clothing industry uses chemicals to manufacture some cotton fabrics that are wrinkle-free. Dyes are also added to color the cellulose fibers in cotton. Based on what you read, what are cellulose and sugar? Elements, compounds, or mixtures?

You can find nitrogen (N) in the atmosphere. We breathe it in like we breathe in oxygen. You can also find nitrogen in other things, too. You can find nitrogen in ammonia (a poisonous liquid that is use to disinfect), steel production, coolant (this is found in a refrigerator to keep things frozen), oil and petroleum production, and in soil nutrients. What can you conclude about the nitrogen you breathe?
It is the SAME nitrogen atom that is used in ammonia, steel production, coolants, oil and petroleum production, and soil nutrients.
