Scientific Method
100
A water molecule is attracted to a different type of molecule, like water being attracted to glass.
What is adhesion?
100
This element bonds with many important elements to form life.
What is carbon?
100
Molecules of a mixed substance are evenly spread out (dissolving happens).
What is a solution?
100
A process that changes one set of chemicals into another set of chemicals.
What is a chemical reaction?
100
The first step of the scientific method. You may use your sight or another sense.
What is observation?
200
Water is attracted to another water molecule, like when the water bubbled on the penny and formed a ball.
What is cohesion?
200
This macromolecule provides fast energy for living things.
What are carbohydrates?
200
A mixture of water and a substance that does NOT dissolve.
What is a suspension?
200
A substance that speeds a chemical reaction.
What is a catalyst?
200
The last step of the scientific method. You summarize what you discovered.
What is conclusion?
300
Water molecules stick together at the surface and support certain things like a water strider or a square of aluminum foil.
What is surface tension?
300
This macromolecule provides insulation and long term energy for organisms.
What are lipids?
300
Lemon and tomato juice are examples of these.
What are acids?
300
A protein that acts as a catalyst.
What is an enzyme?
300
You conduct this to test your hypothesis.
What is experiment?
400
The term that describes a water molecule having a positive and negative charge.
What is polar?
400
This macromolecule helps to build muscle, support the immune system, and speed up chemical reactions in the body.
What is protein?
400
Soap and baking soda are examples of these.
What is a base (or something basic)?
400
Energy needed to get a reaction started.
What is activation energy?
400
You write down your results in a chart/table/graph, for example.
What is record (data)?
500
The bond between water molecules.
What is a hydrogen bond?
500
This macromolecule stores genetic information (DNA/RNA).
What are nucleic acids?
500
This substance can react with an acid or base to stop sudden changes in pH.
What is a buffer?
500
Another name for smell, something that can be given off when you smell vinegar.
What is odor?
500
You think about what you want to test, write an educated guess using an If...then statement.
What is hypothesis?
