A fight between two scientists in the lab setting
A hypothesis is:
The main argument of the experiment
An element of the process that questions something scientific
Research that is done on the topic
A prediction as to the results based on background information
In order to write a quality hypothesis, a scientist should first:
Make observations
Figure out why he/she got the results they got from the experiment
Conduct research from reliable sources
Continue growing and learning as a scientist
The independent variable is
The part of the experiment the scientist purposely changes
The part of the experiment the scientist measures and records
The part of the experiment the scientist purposely keeps the same
The part of the experiment that can be ignored
The dependent variable is
The part of the experiment the scientist purposely changes
The part of the experiment the scientist measures and records
The part of the experiment the scientist purposely keeps the same
The part of the experiment that can be ignored
The control variable is
The part of the experiment the scientist purposely changes
The part of the experiment the scientist measures and records
The part of the experiment the scientist purposely keeps the same
The part of the experiment that can be ignored
When planning an experiment, a scientist should consider
The control variables so that only one independent variable is being tested
The number of trials to be conducted so that accuracy is ensured
The materials that will be needed
All of the above
Data and observations
Should be collected as the experiment is being conducted
Should be organized into tables
Provides the information that supports or denies a hypothesis
All of the above
Qualitative data
Is observed by senses and described using words
Should be the only source of information for scientists
Is not as important as quantitative data
All of the above

All of the above
Graphs help scientists
Analyze the data they collected
Collect new data
Decide if the data is accurate or not
None of the above
When writing a results paragraph to analyze data, a scientist should:
Describe the data in paragraph form including trends and patterns
Consider it the last step of the scientific method
Complete it prior to beginning the actual experiment to understand others’ findings
Compare the original research and experimental research
A conclusion should include
A statement of the major findings
Future research to be conducted
Possible sources of error
All of the above
An appropriate problem for the experiment that yielded this data would be:
What is the effect of height of ball bounce on ball type?
How high will a ball bounce based on the type of ball used?
Do different types of balls bounce differently?
How does ball type affect the height of a ball bounce?
16. An appropriate hypothesis for the experiment that yielded this data would be:
If different types of balls are bounced, then a golf ball will bounce the highest because of the material it is made of.
Different balls will bounce different heights if dropped.
Yes, different balls bounce differently; a tennis ball will always bounce highest.
If height is measured, tennis balls will bounce higher.
The conclusion for this experiment would be:
Ball type affects bounce height and tennis balls bounce the highest.
Ball type affects bounce height and ping pong balls bounce the highest.
Bounce heights affects tennis balls the most
There is no effect of ball type on how high they bounce.

After the song was over, she measured everyone’s pulse and blood pressure again. Which of the following hypotheses best fits this scenario?
If soothing music is played, then people’s blood pressure and pulse will decrease.
If people’s blood pressure and pulse decreases, then music should be played.
If people sit in silence, music will start playing.
If a song ends, blood pressure should be measured.

Timmy and Billy just finished an experiment to determine how the moon’s position changes in relationship to the sun. Tim and Billy went outside each day at the same time and measured the distance between the positions of the moon and the sun in the sky. They also sketched what the moon looked like each day. Their initial hypothesis was, “It is hypothesized that there will be no change in the relationship between the moon and the sun from day to day because the moon revolves around the Earth at a constant speed.” Here is the completed data from their experiment. Which of the following conclusions is best supported by the data?
During the experiment the moon appeared closer to the sun each day, with the exception of the first day where the moon was not visible in the sky.
Each day, at the same time, the moon moved farther away from the sun with the exception of the first day where the moon was not visible in the sky.
During the experiment the moon moved in closer and then farther away from the sun.
During the experiment there was no relationship between the how much of the moon was visible and the distance between the moon and the sun.

Timmy and Billy just finished an experiment to determine how the moon’s position changes in relationship to the sun. Tim and Billy went outside each day at the same time and measured the distance between the positions of the moon and the sun in the sky. They also sketched what the moon looked like each day. Their initial hypothesis was, “It is hypothesized that there will be no change in the relationship between the moon and the sun from day to day because the moon revolves around the Earth at a constant speed.” Here is the completed data from their experiment. How should they refine their hypothesis based on the results from this investigation?
There is no relationship between the moon’s position the Sun at the same time each day, because the Earth’ speed is constant.
There is not a relationship between the moon’s position to the sun from day to day, because the position never increased.
There is a relationship between the moon’s position in relationship to the sun, because the distance increases between the two objects each day.
The distance between the moon and the sun at a given time changes and the phases of the moon are created by the moon’s position to the sun relative to the earth.

Your science group studied the populations of organisms within a grassland biome food chain. You recorded the number of organisms in a grass, sheep, and wolf population. You then turned your data into a graph in order to better help you analyze the results. You realized that the populations do, indeed, fluctuate over time. Your data also has some surprises to it! Your group lost points on this graphical representation of data. Why could that be?
The title isn’t in proper scientific format including both variables
The axes aren’t clearly labeled with number and unit
Both A and B
Neither A nor B
Your science group studied the populations of organisms within a grassland biome food chain. You recorded the number of organisms in a grass, sheep, and wolf population. You then turned your data into a graph in order to better help you analyze the results. You realized that the populations do, indeed, fluctuate over time. Your data also has some surprises to it! Which hypothesis was most likely being tested in this experiment?
If the food chain is left untouched by humans, then the populations of organisms will stay in the same number.
If the food chain is left untouched by humans, then the populations of organisms will fluctuate and balance.
If predator and prey are in the grasslands, there will always be more prey because of the energy pyramid requirements.
If primary consumers are present, the producers’ population size will never drop below the herbivores because of the energy pyramid requirements.

Koho Trial 2
Mission Trial 3
Koho Trial 1
What conclusion can be made from the data?
The averages are almost the same so no major difference is seen.
The puck traveled the farthest distance in trial 2 using a Mission stick; so that is the best one.
The puck traveled the shortest distance in trial 3 using a Mission stick; so that is the worst one.
The average distance traveled when using a Mission stick is the farthest; so that is the best one.
