Parts of the Scientific Method
Notice something in the world and use your senses to gather initial information.
What is an observation?
The element all organic compounds need to have.
What is carbon?
Anything that has mass and takes up space.
What is matter?
The change of one substance into another.
What is a chemical reaction?
The electrical charge difference between areas of a molecule.
What is polarity?
Form a clear, specific question about what you observed.
What is a question?
Carbohydrates, lipids, proteins, and nucleic acids.
What are macromolecules?
This thing has the same type of atom.
What is an element?
Chemical reactions are shown by this.
What is a chemical equation?
What are hydrogen bonds?
Look at existing data, past studies, or books to learn what is already known.
What is background research?
A class of organic compounds includes DNA and RNA, which store and transmit genetic information.
What are nucleic acids?
2 or more elements bonded together.
What is a compound?
The rule that matter cannot be created or destroyed under normal conditions.
What is the law of conservation of matter?
Measures the concentration of hydronium ions.
What is pH?
Propose a testable, possible explanation or "if-then" prediction for your question.
What is a hypothesis?
Glucose and cellulose belong to this macromolecule group, which serves as a primary energy source for living things.
What are carbohydrates?
The amount of space an object takes up.
What is volume?
A reaction where energy is emitted.
What is an exothermic reactions?
Any compound that forms H+ ions in solution
What is an acid?
Decide whether your results support or reject your hypothesis.
What is a conclusion?
The hydrophobic category of organic compounds includes fats, oils, and waxes used for long-term energy storage.
What are lipids?
Solid, liquid, gas, and plasma.
What are the states of matter?
A reaction where energy is absorbed.
What is an endothermic reaction?
A compound that produces hydroxide ions in solution.
What is a base?
