100
A testable explanation or idea that leads to further investigation.
What is a hypothesis?
100
Information gathered through observation and experimentation that may be used in calculating or reasoning.
What is data?
100
This type of model looks like the object it represents. it can be diagram on paper or it can be 3-dimentional. Usually these models represent real objects that too big or too small for us to see in real life.
What is a physical model?
100
Scientific investigations include many different steps. Which step occurs after a scientist collects data? (a) draw conclusions (b) form the hypothesis (c) plan the experiment (d) follow the procedure
What is (a) draw conclusions
100
Which scientist would be responsible for conducting research on sedimentary rocks of the Jurassic period.
What is a geologist?
200
This is a general a term for a factor that changes in an experiment.
What is a variable?
200
The data used for representing measures in expressed in quantities or numbers.
What is quantitative data?
200
You are given a diagram representing a water molecule. What type of model would that be?
What is a physical or visual model?
200
Before a scientific idea is modified, new data is usually introduced which may create changes in scientific knowledge to the original idea. What would scientists do just before this idea is modified?
What is "debate the change"?
200
Where would an ecologist conduct investigations?
What is in "field work"?
300
An organized procedure used to study something under control conditions.
What is an experiment?
300
Experimenting is an exciting part of science, but the data gathered from your experiment must be properly organized, so that you and those looking at your results can draw conclusions about the problem you are investigating. There are two very important steps:What are they?
What is (1) Create a data table and (2) Create a graph?
300
The process plants use to make their own food is known as photosynthesis is summarized by the following chemical equation: Light Energy 6H2O + 6CO2 → C6 H12 O6 + 6O2 This equation represents what type of model.
What is a mathematical model?
300
Students in a lab measure the mass and volume of an object to calculate the density. What would increase the accuracy and validity of the experiment? a) changing the procedure b) varying the equipment c) have each student individually calculate the density d) repeating the experiment and analyzing all the data
What is "repeating the experiment and analyzing all the data"?
300
True or False: According to Boyles law, as the pressure of a gas increases the volume increases while the temperature is kept constant.
What is "False"? The volume of the gas will decrease, as pressure increases, and particles get closer together.
400
A pattern, plan, or representation or description designed to show the structure or workings of an object, system or concept
What is a model
400
There are three (3) very important things that must be present on a data table. Name them.
What is (1)the title that identifies the variables placed at the top of the table (2)the column and row labels (3) units of measurements if applicable?
400
Physical models show structure and connections and interactions of a system. Mathematical models use numbers and data to make predictions. Conceptual models show relationships and provide mental ways of representing complex ideas. What type of model would a taxonomy of organisms represent?
What is a conceptual model?
400
Many experiments require several trials instead of a single trial. Why is this? a) Several trials make data easier to analyze. b) Several trials increase the accuracy of the results. c) Several trials increase the sample size of the experiment.
What is (b) Several trials increase the accuracy of the results.
400
Controlled experiments include variables. What is the difference between a dependent variable an independent variable?
What is "dependent variable responds to the change of the independent variable"? dependent variable is the outcome variable independent variable is the manipulated(changing) or test variable.
500
A factor that is changeable, and manipulated in an experiment. On a graph it is usually plotted on the x-axis.
What is an independent variable?
500
When representing data on a graph, on which axis is the dependent variable likely to be found?
What is the y-axis?
500
A weather person on television is giving a forecast of the weather showing a description of how an impending storm may develop into a hurricane and tracking its course. What type of model might the meteorologist be using?
What is a conceptual or computer model?
500
Two scientists have different ideas about a scientific concept. What might they do to resolve their differences?
What is "Debate their ideas using evidence they have gathered through observation and research"? Then they come to a consensus about a scientific idea.
500
Deandra investigates how far a rubber band stretches when she suspends an increasing amount of weight from it. There are two variables in this experiment. One is "weight(N)" and the other is "stretch(cm)". Which of these variables is dependent?
What is "stretch"
