Experiments often begin with an ________.
observation
conclusion
hypothesis
analysis
Making an observation means using your ________ to gather ________.
senses, information
hands, tools
eyes, data
ears, results
Give an example of an observation based on the following:
The ice cube melts faster in a dark cup than in a light cup.
Ice cubes are made of water.
Cups come in different colors.
Melting is a physical change.
The goal of an experiment is to answer a __________.
question
theory
hypothesis
formula
Scientific questions must be __________.
testable
opinion-based
unanswerable
random
You can answer a testable question by conducting an __________.
experiment
guess
discussion
observation
You can answer a testable question by analyzing the __________ results.
measurable
random
subjective
imaginary
A possible ________ to a scientific question is known as a hypothesis.
answer
experiment
variable
observation
A possible answer to a scientific question is known as a __________.
hypothesis
experiment
observation
conclusion
A hypothesis is usually written in the form of an __________ statement.
if/then
cause/effect
yes/no
true/false
Variables are ________ that can ________ or be changed within an experiment.
factors, change
constants, remain
results, appear
tools, measure
The independent variable is the variable that is purposely __________ or changed in an experiment.
manipulated
measured
recorded
observed
The dependent variable is what is being observed or __________ in an experiment.
measured
created
destroyed
ignored
Controlled variables are parts of an experiment that must be kept __________ and unchanged so that the __________ are valid.
constant, results
variable, answers
random, outcomes
different, experiments
List at least 3 things we will need to control in the experiment: "Does color affect temperature?"
1. Location 2. Size of Beakers 3. Amount of time in the Sun
1. Type of thermometer 2. Brand of beakers 3. Color of table
1. Day of the week 2. Type of shoes worn 3. Number of pencils used
1. Music played during experiment 2. Type of paper used for notes 3. Color of experimenter's shirt
Scientists will often divide an experiment into _____ groups. The only difference between the groups is that the __________ group will ________ the treatment, and the __________ group will __________ the treatment.
two, experimental, receive, control, not receive
three, control, receive, experimental, not receive
two, control, not receive, experimental, not receive
four, experimental, not receive, control, receive
It is important to have a control group because:
it allows for comparison to determine the effect of the variable being tested.
it guarantees the experiment will succeed.
it eliminates the need for data analysis.
it ensures all results are identical.
Scientists collect ______ (evidence) so that they can analyze the ______ of an experiment and ______ the original question.
data, results, answer
facts, answers, question
samples, solutions, solve
information, outcomes, ask
The evidence must be ______ and ______.
appropriate, sufficient
relevant, excessive
limited, vague
incomplete, biased

White: 1
According to the data table, which color had the lowest average temperature increase?
Yellow: 2
Blue: 4
Green: 3
Black: 7
White: 1
Which graph correctly displays the average temperature increase for each color using the data table, with the x-axis as 'Color of Beaker' (Yellow, Blue, Green, Black, White) and the y-axis as 'Temperature Increase (°C)'?
A bar graph labeled 'Average Temperature Increase of Colors' with the x-axis as 'Color of Beaker' and the y-axis as 'Temperature Increase (°C)'
A line graph with the x-axis as 'Time' and the y-axis as 'Temperature'
A pie chart showing the percentage of each color
A scatter plot with random data points
