Question | Answer |
What was the medieval science of chemistry called? | Alchemy |
The medieval science that was a forerunner of chemistry | Alchemy |
The tendency to see what we want to see, or interpret data according to expectations, and build scotomas to other data | Bias |
A field of science that studies MATTER (and how it is changed due to energy) | Chemistry |
A variable that is kept the same for all groups in an experiment | Constant |
A group in an experiment that is used for comparison. | Control |
The variable in an experiment that is changed depending on the value of the other variable. | Dependent variable |
The branch of science that studies earth and space | Earth Science |
These test a hypothesis by investigating the effect of one variable on another in a controlled environment. | Experiments |
These are used to better "see" relationships in science. | Graphs |
A possible, testable solution to a problem in science, based on research and observation | Hypothesis |
The variable in an experiment that is adjusted or changed by the experimenter. | Independent variable |
The branch of science that studies living things | Life Science |
Used in science to represent ideas or objects that are too large or complex, so that people will understand it better | Model |
The branch of science that studies matter and energy. | Physical Science |
The field of science that studies ENERGY (and the effect it has on matter) | Physics |
Based on the Latin word SCIENTIA, which means "knowledge" | Science |
The organized set of procedures followed by scientist to investigate the natural world. | Scientific Method |
A rule or principle that describes WHAT happens in nature | Scientific Law |
The application of science to help people | Technology |
An explanation of HOW or WHY something happens, based on repeated observations and experiments. | Theory |
Something that is subject to change | Variable |
When one variable increases as the other increases, and produces a straight line sloping up, we say they are ____proportional | directly |
If two variables are indirectly proportional, one goes down as the other goes up, and the line produced slants | Downward |
The type of graph usually used when comparing the change in one variable with the change in another is a | Line graph |
Which type of graph is used to "see" percentages? | A circle or pie graph |
This type of graph is used when "counting" data. | A bar graph |
On a data table, the first column represents the | Groups or Trials |
On a data table, what variable is placed in the 2nd column? | The independent variable |
On a data table, where do we record the data gathered on the dependent variable? | The third column. |
What are some ways scientists can reduce bias in their experiments? | They can repeat the experiment, or ask another person to repeat the experiment. |
What are 3 ways a scientist uses to investigate nature? | Observation, experimentation, modeling |
How does an observation differ from an inference? | Observations are made with the 5 senses. Inferences are guesses based on knowledge or past experience. |
What are the most commonly listed steps of the Scientific Method? | State the Problem
Form a Hypothesis
Test the Hypothesis(Experiment)
Analyze Data (Charts or Graphs)
Form a Conclusion
Repeat the experiment(to reduce bias) |
If an experiment recorded a cricket's chirps at different temperatures, what might you title a graph for that experiment. | Temperature vs Chirps
Crickets' Chirps at Varying Temperatures
How does Temperature Affect the Rate of Cricket's Chirping?
(Include both variables in the title. |
Know how to construct and read a line graph | Remember, you must always include a Title, label the x-axis and the y-axis, and number each axis. You must also draw a smooth line for the graph (DO NOT CONNECT THE DATA POINTS) |
