What is the first step in the scientific method?
Ask a question
Hypothesis
Conclusion
Analyze data
A student wants to perform a science experiment about plants. He wants to know if a certain type of soil will make plants grow taller. Each pot will receive a different type of soil, but will get the same type of seed, water amount, and sunlight amount.What is the Independent Variable in this story?
Amount of sunlight
How tall the plant will grow
Amount of water
Type of material the plant is growing in
What do you measure for results (outcome)?
Dependent variable
Hypothesis
Experimental Group
Constants
If an animal shelter wants to see if a certain dog food causes a dog to gain weight, which of the following would NOT be a constant?
Type of dog food given
Amount of dog good given
Time of day food is given
Amount of exercise dog is given
Why is it important to have constants in an experiment?
To make sure the experiment is fair
Constants are not needed for experiments.
To measure the dependent variables all at once
To test many variables at a time
This bar graph shows the number of cheeseburgers sold at McYummies drive thru last week. Study the graph and answer the following question.
What was the maximum number of burgers sold, and on which day was this?
30 burgers on Tuesday
60 Burgers on Thursday
20 Burgers on Thursday
25 Burgers on Monday
Which of the following is not an example of quantitative data?
Temperature
Speed
Height
Texture
Anna is in charge of studying how the amount of plant food (fertilizer) affects the height of a plant at a local garden. Which testable statement does she investigate?
There is no way to test this hypothesis.
If a plant receives two cups of food per day, then the height of the plant will increase
If a plant gets different amounts of water and two cups of food per day, the height of the plant will increase
If a plant receives more sunlight, the height of the plant will decrease
Why do many experiments include several trials instead of a single trial?
Repetition of trials increases the accuracy of the results
Repetition of trials decreases the sample size of the experiment.
Repetition of trials makes data easier to analyze.
It is not necessary to repeat trials
1. Aside from repeating a scientific experiment, what else must a scientist do to increase the accuracy of the results?
Change the hypothesis
Share data with other scientists for them to repeat or replicate
Analyze the data faster
Keep the data for themselves
Quantitative data can be
seen
measured
manipulated
heard
How is a hypothesis different from a theory?
A theory has evidence to back it up and a hypothesis is an educated guess as to what is going to happen.
They are both the same. They both are guesses as to what happens in the natural world.
A theory is an opinion about how something works but a hypothesis has scientific evidence to support it.
A hypothesis is used in science and a theory is used in society.
Qualitative data uses
a thermometer
your different senses
a test tube
a ruler
