The Scientific Method
A scientist conducted an experiment to determine how the amount of salt in a body of water affects the plants that can live in the water. In this experiment the independent variable is
A) the types of plants or B) the amount of salt in the water
B) the amount of salt in the water
Name the 3 types of graphs we learned in class so far.
They are: bar graph, line graph, and circle graph.
What is the Scientific Method?
A step-by-step process used to answer questions.
All living things are made of ________.
cells.
Why does a biologist use a microscope?
To observe/study microscopic organisms.
A possible explanation or answer to a scientific question that can be tested in an experiment.
A hypothesis.
On a graph, the Y-axis contain which variable?
The dependent variable.
Which of the following hypotheses is written most correctly?
A) If a tennis ball is frozen, it won't bounce as high
B) If I heat up a tennis ball it will bounce high.
C) Frozen tennis balls will not bounce as high.
D) If I freeze a tennis ball, then it will not bounce as high.
D) If I freeze a tennis ball, then it will not bounce as high.
Living things require _________ which they get from food they eat.
energy.
This microscope part's function is "to show detail clearly."
Resolution.
A hypothesis must be stated in what form?
if, then.
The variable that is deliberately changed/manipulated
A. | Dependent |
B. | Independent |
C. | Control |
D. | Uncontrolled |
B- Independent
Gathering information by using your senses.
Observation.
"All living things grow and develop." Define the term, cell differentiation.
Cell differentiation = cell specialization.
The revolving nosepiece contains 3/4 "long tubes" known as _____________.
Objectives (SCANNING - LOW - HIGH).
Difference preservatives were tried in foods to determine which best restricted the growth of molds. What is the dependent?
Growth of Mold.
Explain the difference between the terms, "interval" and "scale?"
An interval is the number you skip by on an axis.
A scale is the range of numbers on an axis (smallest # - largest #).
This scientific term is known as to be "descriptive or physical data."
Qualitative Data.
"All living things evolve." Define the term, evolution.
Evolution = the process by which a species changes over time.
When properly holding a compound light microscope, which two microscope parts are involved?
The arm and the base.
What are the steps to the scientific method?
5: Ask Question, Form Hypothesis, Create Experiment, Analyze Data, and Form Conclusion.
In graphing, what does TAILS stand for?
T: Title.
A: Axis.
I: Interval.
L: Labeling.
S: Scale.
A researcher conducted an experiment to see if temperature effected the blooms of a rose bush... What is the independent variable?
The temperature.
In biology, what is the difference between the terms "population" and "community?"
A population is all of the organisms of the same species in the same place at the same time.
A community is all populations in the same place at the same time (all living things).
The CELL THEORY has three parts. The first part is "All living things are composed of cells." Name the other two parts.
2. “Cells are the basic units of structure and function in living things.”
3. “All cells are produced from other cells.”
