Scientific Method
The order of the scientific method process.
1. Ask a question
2. Conduct background research
3. Construct a hypothesis
4. Test your hypothesis
5. Analyze data
6. Draw conclusions and communicate
What the experimenter will deliberately change or manipulate in the investigation.
What is an independent variable?
The small, basic unit.
What is a monomer?
Short-term energy is the main function of this.
What is a carbohydrates?
The monomer of nucleic acids.
What is a nucleotide?
Description of something you can see, smell, touch, taste, and hear.
Questions are based on this.
What is an observation?
What changes in response to the independent variable.
What is a dependent variable?
The complex structure made of monomers.
What is a polymer?
Monomer and polymers of carbohydrates.
What are monosaccharide and polysaccharide?
The two types of nucleic acids.
What is DNA and RNA?
A hypothesis should be stated in this format describing cause and effect.
What is an “If … then …” statement?
Groups that are being tested.
What is an experimental group?
The macromolecule that is never broken down.
What is a nucleic acid?
Other functions of this macromolecule include cushioning organs, insulation, hormones, cell membrane.
What are lipids?
This protein functions in helping fight disease.
What are antibodies?
Makes an explicit statement about whether your hypothesis was supported or rejected by your experimental data.
What is a conclusion?
The aspects of an experiment that are held constant/consistent ensuring all aspects of trials are identical, except for the IV, and any difference measured in the DV is caused by the IV.
What is a constant?
First carbohydrates,
then lipids,
then proteins.
What is the order that macromolecules are broken down?
The type of lipid that makes up the cell membrane.
What is a phospholipid?
This protein functions in controlling the rate of chemical reactions.
What are enzymes?
The two types of observations.
What is qualitative and quantitative observations?
Tests to ensure results are not due to change, errors, and that data is precise.
What are repeated trials?
All molecules (including macromolecules) that contain carbon.
What are organic molecules?
The two types of fatty acid molecules.
What are saturated and unsaturated fatty acids?
The type of bond holding amino acids together in a chain.
What is a peptide bond?
