2
The first step of the scientific method is to...
collect data.
share information.
observe.
design an experiment.
3
When preparing for an experiment, a source to gather information is:
Your 5 senses
Current science textbooks
All the above
Websites from scientific or academic institutions
4
How should data be collected during an experiment?
based on predictions
based on observations
based on previous research
based on personal opinions
5
An inference is a logical conclusion
True
False
6
What is a good scientific question?
What types of light do plants grow the fastest?
Where do plant grow fast at?
How does sunlight work on plants?
What effect do different types of light have on plant growth?
7
According to Darwin, many traits are passed
from parents to offspring.
between brothers and sisters.
between unrelated individuals.
from offspring to parents.
8
The third step of the scientific method is...
forming a question.
analyzing data.
recording results.
conducting an experiment.
9
Engineering Design Process
a series of steps that engineers follow when trying to solve a problem
makes problems more complicated
is the same as the scientific method
is a made up thing and doesn't exist
10
Which of the following statement(s) can you conclude based on your observations?
Food made by the leaves below part X can be transported down to the roots.
Water cannot be transported from the roots to the leaves above part X.
Both the food and water-carrying tubes above part X are not damaged.
Only the food-carrying tubes of the plant are damaged.
11
Identify the independent variable in this experiment.
The type of plant.
The type of soil.
The height of the flower.
Amount of sunlight.
12
A possible, testable answer to a scientific question
conclusion
procedure
trial
hypothesis
13
In a plant experiment, what question is most likely being investigated?
At what temperature do plants grow tallest?
How many hours of light does a plant need?
Does the color of light affect plant height?
How much light do plants need to grow?
14
Identify the dependent variable in this experiment.
The type of soil.
The amount of sunlight.

The type of plant.
15
In experiments, subjects that receive special treatment are known as...
the experimental group
the control group
the correlational group
the observational group
16
How can we ensure an experiment is reproducible?
Get someone else to repeat the experiment and compare results
Repeat the experiment yourself and compare results
17
What is the difference between a hypothesis from an observation in a scientific experiment?
a step-by-step procedure the other is a statement of purpose.
a list of materials used in an experiment and an observation is the truth
hypothesis is a prediction using prior knowledge, observation is a result
A hypothesis is a measurement, while an observation is an educated guess.
