Nature of Science
This is a statement based directly on something using your senses or measurements.
Observation
What is the smallest unit of matter that retains the properties of an element.
atom
This property describes water molecules sticking to other water molecules.
Cohesion
The small building blocks that makes up polymers are called these.
monomers
This macromolecule is commonly used as a quick energy source?
carbohydrates
This is a testable prediction about a possible relationship between variables.
Name the six elements identified as necessary for life.
C H O N P S
This property describes water sticking to other surfaces or substances.
adhesion
What is the monomer of a carbohydrate?
monosaccharride
This macromolecule is important for long-term energy storage and is also a major component of cell membranes.
lipids
This type of data describes characteristics using words rather than numbers.
Qualitative data
Put these levels of organization in order from smallest to largest; organism, atom, cell, molecule
Atom --> Molecule --> Cell --> Organism
This property allows water to resist changes in temperature.
High specific heat
What is the monomer of a protein?
amino acids
This macromolecule performs many functions in cells, including providing structure and acting as enzymes.
proteins
What is the difference between accuracy and precision?Draw a picture representing your answer and use labels.
Target with labels
A molecule with an uneven distribution of electrical charge is called this.
Polar molecule
Why is solid water less dense than liquid water?
The molecules in solid water ware arranged in a structure that takes up more space, making ice less dense than liquid water.
What are the monomers of nucleic acids?
nucleotides
This macromolecule stores and transmits genetic information.
nucleic acid
Put these terms in order from a specific explanation supported by evidence to broader scientific explanations: fact, principle, law, theory
Fact --> Principle --> Law --> Theory
Explain the difference between a polar molecule and a nonpolar molecule.
Polar molecules have an uneven distribution of charge, while a nonpolar molecule has a more even distribution of charge.
Name three properties of water that make it especially important for life.
cohesion, adhesion, high specific heat, less dense as a solid, or being an excellent solvent.
Students test whether different types of fertilizer affect plant growth. What is the independent variable?
type of fertilizer
Students test whether different types of fertilizer affect plant growth. What is the dependent variable?
plant growth
