What is the independent variable?
This is typically the first step of the scientific method and involves examining the world around you using the five senses.
What is observation?
This is the smallest part of an element that still has the properties of that element.
What is an atom?
A large organic molecule that makes up living things.
What is a macromolecule?
What is the difference between polar and non polar molecules?
Polar: Unequal distribution of charges
Nonpolar: No separation of charge
A subjective guess or conclusion based on an observation and personal experience.
What is an inference?
This factor is what changes in response to something in an experiment; it is measured and collected as data.
What is the dependent variable?
This step involves recording data, making tables, and constructing graphs.
What is results?
This means that the substance is "water loving" and tends to dissolve in water.
What is hydrophilic?
These are small basic units that make up larger more complex molecules (monosaccharides, amino acids, fatty acids, nucleotides).
What are monomers?
An explanation of an observed phenomenon based on research and consistent supporting evidence.
What is a theory?
Parts of an experiment that are kept consistent across all trials and groups.
What are constants?
This is the step where data is evaluated and trends are highlighted.
What is analysis?
This describes substances' ability to stick to molecules of the same substance.
What is cohesion?
These are larger more complex structures that are made of smaller foundational units (polysaccharides, polypeptides, nucleic acids, triglycerides).
What are polymers?
A broad concept or principle that describes how something occurs in nature, often with a mathematical relationship.
What is a law?
The group(s) being tested.
This step is where scientists decide whether their hypothesis was supported or rejected.
What is conclusion?
This describes how well molecules stick to different types of molecules.
What is adhesion?
This special type of lipid makes up the selectively permeable membrane of cells.
What is a phospholipid?
The application of scientific discoveries to meet human needs and goals through the development to products and processes.
What is technology?
The standard/normal group used for comparison.
What is the control group?
This is the "final" step of the scientific method and involves publishing results, sharing research at conferences, and peer review.
What is communication?
This property describes how much energy it takes to change the temperature of a substance.
What is specific heat?
What is form, shape, or folding?
