Nature of Science
This term refers to an observation that has been repeatedly confirmed and accepted as true.
What is a fact?
This term refers to anything that has mass and takes up space.
What is Matter?
This is the elastic tendency of a fluid surface that makes it acquire the least surface area possible.
What is surface tension?
This is the simplest form of carbohydrate (e.g., glucose).
What is a monosaccharide?
This is a positively charged ion.
What is a cation?
This term describes a fundamental truth that serves as the foundation for a system of belief or behavior.
What is a principle?
This is the smallest unit of an element that retains the properties of that element.
What is an Atom?
This property of water causes ice to be less dense than liquid water, allowing it to float.
What is the density anomaly of water?
This is a large molecule made up of repeating units of monomers.
What is a polymer?
This type of data is numerical and can be measured.
What is Quantitative Data?
This type of data is descriptive and involves characteristics that cannot be counted.
What is qualitative data?
These are the electrons in the outermost shell of an atom that are involved in forming bonds.
What are Valence Electrons?
This is the substance that is dissolved in a solution.
What is a solute?
This is a carbohydrate whose molecules consist of a number of sugar molecules bonded together.
What is a polysaccharide?
This is the substance that dissolves the solute in a solution.
What is a solvent?
These variables remain unchanged throughout an experiment to ensure that the effect of the independent variable can be measured.
What are Constants/Controlled Variables?
These are atoms of the same element that have different numbers of neutrons.
What are Isotopes?
This property of water allows it to stick to itself due to hydrogen bonding.
What is cohesion?
This is a small molecule that can join with other similar molecules to form a polymer.
What is a monomer?
This property of water allows it to stick to other substances.
What is adhesion?
Double Jeopardy: Describe the role of the experimental group in a scientific experiment. How does it differ from the control group?
The experimental group is the group in an experiment that gets the treatment or variable being tested. Scientists observe how this group reacts to understand the effects of the treatment.
The control group does not get the treatment. It serves as a comparison to see if the treatment has any effect. This helps scientists know if the changes in the experimental group are really due to the treatment.
Double Jeopardy: Explain the relationship between matter and atoms. How do atoms combine to form compounds?
Matter is anything that takes up space and has mass. Atoms are the tiny building blocks that make up matter. Atoms combine by sharing or transferring electrons to form chemical bonds. This creates molecules and compounds, like water (H₂O) which is made of hydrogen and oxygen atoms.
This property of water allows it to absorb a lot of heat before changing temperature.
What is high specific heat?
Double Jeopardy: Compare and contrast monomers and polymers. Provide examples of each in biological systems.
Monomers: Small, single molecules that can join together to form larger molecules. Examples include glucose (a sugar) and amino acids (building blocks of proteins).
Polymers: Large molecules made up of repeating monomer units. Examples include starch (made of glucose units) and proteins (made of amino acids).
Double Jeopardy: What is 250 mL in liters?
0.25 L
