A possible explanation for a set of observations or answer to a scientific question is called a __________________.
Prediction
Hypothesis
Theory
Law
During an experiment, if you purposely change the temperature to test a hypothesis, the temperature is called the ____________.
Variable
Dependent variable
Independent variable
Controlled variable
The factor that may change in response to the independent variable is called the ______________.
Variable
Dependent variable
Independent variable
Controlled variable
Using 1 or more of the senses to gather information is called a(n) ___________________.
Observation
Inference
Prediction
The variables that are kept the same (constant) throughout the entire experiment are called ______________.
Independent variables
Dependent variables
Controlled variables
Manipulated variables
(a) are facts, figures and other evidence gathered through observations.
What is the next step in the scientific method after conducting background research: form a (a) .
What is the next step in the scientific method after forming a hypothesis: design an (a) .
Choose the best-written hypothesis that answers the question:
Question: Why is my room warmer during the day than at night?
Sunlight is making my room warmer.
Mr. Glass has the heat turned on in the morning.
If I close my blinds during the day, then my room will be cooler because sunlight cant get in.
Sunlight actually cools down a room.
When should you write a hypothesis?
After writing procedures
After making observations and doing research on a question/problem
After buying materials for an experiment
At the very beginning of the experiment
Which of these contains the steps of the scientific method in the correct order?
Ask a question, do background research, state your hypothesis, conduct an experiment, analyze data, make a conclusion, share results
State your hypothesis, ask a question, do background research, conduct an experiment, analyze data, make a conclusion, share results
Ask a question, state your hypothesis, do background research, conduct an experiment, make a conclusion, analyze data, share results
State your hypothesis, ask a question, do background research, make a conclusion, conduct an experiment, analyze data, share results
This is the group that is affected by the variable or the group that is changed.
Control Group
Experimental Group
Changed Group
Cool Group
An inference is based on:
both scientific observations and known facts
known facts
scientific observations
a rumor you started in the bathroom
What is empirical evidence?
Information acquired through observation or experimentation
Information acquired through logical reasoning
Information acquired through personal anecdotes
Information acquired through intuition
A theory is
proven
supported a large body of evidence
both
Newtons law
A scientific LAW
is a societal rule we must obey
describes what is happening, but not why
explains why something happens
explains why theories occur
Scientists form _________ hypothesis to answer questions.
accurate
short
mathematical
testable
How can we collect empirical evidence?
Through our own personal beliefs and bias
Through experimentation, investigations, and observations.
Predictions from only mathematical models.
Predictions from only 3-D physical models.
If something new is discovered in science, what will most likely happen?
The scientific knowledge may change as long as there is empirical evidence to support it.
Science will be called inaccurate and untrustworrthy.
The scientists that discovered the new information will be fired from their research positions.
None of the above.
Is science accepted as fact right away?
No, knowledge must be discussed and debated with other scientists before it is confirmed and accepted.
Yes, if a scientists discovers something it does not need to be replicated or repeated.
How can we collect empirical evidence?
Through our own personal beliefs and bias
Through experimentation, investigations, and observations.
Predictions from only mathematical models.
Predictions from only 3-D physical models.
Can usually be expressed with a mathematical formula like F = m x a.
law
theory
Describes what will happen under certain conditions.
