Definition: a factor in a controlled experiment that is deliberately changed; also called a manipulated variable
Independent variable
Definition: A tested highly reliable scientific explanation of events
Scientific Theory
What type of reproduction do these organisms undergo? Why?
Sexual reproduction
There are two parents/The baby is NOT identical to either parent
What is label C pointing to?
Proton
What is the attraction of molecules of different substances?
Adhesion
Cohesion
Hydrgen bonds
Macromolecules
Adhesion
Definition: A group in an experiment that is exposed to the same conditions as the experimental group except for one independent variable
Control group
Definition: Something that you experience directly through one of your five senses (sight, hearing, smell, taste, or touch).
Observation
What type of reproduction do these organisms undergo?
Asexual reproduction
There is one parent/The daughter cells are identical to its parent
What is label A pointing to?
Neutron
What type of bonds hold two or more water molecules together, as shown in the picture below?
Hydrogen bonds
Definition: A tentative scientific explanation that can be tested further
Hypothesis
Definition: a type of reproduction in which cells from two parents unite to form the first cell of a new organism
Sexual reproduction
What is this statement an example of?
The plant is tall.
Observation
What is label B pointing to?
Electron
Scenario: One tank of gold fish is fed the normal amount of food once a day, a second tank is fed twice a day, and a third tank four times a day during a six-week study. The fish’s weight is recorded daily.
Independent variable:
Dependent variable:
IV: Amount of food a day
DV: Weight of the fish
Definition: A variable that is observed and that changes in response to the independent variable; also called the responding variable
Dependent variable
Definition: the process of reproduction involving a single parent that results in offspring that are genetically identical to the parent
Asexual reproduction
What is this statement an example of?
The plant is tall because it was watered more.
Inference
What property of water does the picture below demonstrate?
Cohesion
Scenario: Different rose bushes are grown in a green house for two months. The number of flowers on each bush is counted at the end of the experiment.
What are the independent and dependent variables?
IV: Rose bushes
DV: Number of flowers on each bush
Definition: A logical interpretation based on what scientists know
Inference
Definition: genetical material that organisms inherit from their parents
DNA
What type of data deals with numbers?
Qualitative
Quantitative
Experimental group
Control group
Theory
Quantitative
