In the following scenario what is the independent variable?

The number of seeds planted in each pot of soil.

From the following hypothesis find the independent and dependent variables.

I.V. = 30 minute walk each morning; D.V. enjoyment at work

In the following scenario what is the control group?

The pipe buried without the lead.

In the following scenario determine the independent and dependent variables.

I.V. = wearing balloon over head; D.V. = mosquitoes on face.

In the following scenario determine the control and experimental groups.

C.G. = walking normal; E.G. = walking with balloon over head

What is an independent variable?

Is different in the experimental and control groups.

Why do we use the scientific process?

To learn something new about a problem or an event.

Researching a problem or a question

comes before forming a hypothesis.

You design each experiment to...

to compare a known to an unknown.

What is a dependent variable?

The outcome variable that is measured.

Pick which statement is not a question about a problem or observation.

I think there is enough to go around.

Identify the independent and dependent variables in the following hypothesis.

I.V. = use hypnosis on master; D.V. = taken out for a walk

3
From the following hypothesis find the independent and dependent variables.
I.V. = enjoyment at work; D.V. 30 minute walk each morning
I.V. = morning; D.V. walking
I.V. = 30 minute walk each morning; D.V. enjoyment at work
I.V. = 30 minutes; D.V. walking
4
In the following scenario what is the control group?
The pipe buried with the lead.
The pipe buried without the lead.
The standing water.
The size of the hole.
5
In the following scenario determine the independent and dependent variables.
I.V. = walking on the same path; D.V. = mosquitoes on face.
I.V. = mosquitoes on face; D.V. = walking in the same path.
I.V. = mosquitoes on face; D.V. = walking at sunset.
I.V. = wearing balloon over head; D.V. = mosquitoes on face.
6
In the following scenario determine the control and experimental groups.
C.G. = walking normal; E.G. = walking with balloon over head
C.G. = mosquitoes; E.G. = balloon
C.G. = balloon over head; E.G. = no balloon over head
C.G. = walking a path; E.G. = walking at sunset
7
Carefully defining a problem is an opportunity to...
prove that you were right.
learn something new.
find success.
make an experiment.
8
Put the steps of the scientific method in the correct order.
E > C > B > A > D > F
A > C > E > B > D > F
E > C > A > B > D > F
E > A > B > C > D > F
9
Experimental data is
records of observations made during and after an experiment.
measurements of the dependent variable during an experiment.
measurements of constants during an experiment.
all the above.
10
In the following scenario what is the dependent variable.
The competitiveness of the plants.
The number of seeds used in each pot of soil.
The amount of water used for each plant.
The healthiness of the plants.
11
What is an independent variable?
Is different in the experimental and control groups.
The variable that stays constant.
The variable that changes.
The variable that controls the experiment.
12
Why do we use the scientific process?
To keep busy.
To find a good experiment.
To prove something is right.
To learn something new about a problem or an event.
13
Researching a problem or a question
comes before forming a hypothesis.
comes after experimenting.
comes after the experimental results are analyzed.
comes before the question.
14
You design each experiment to...
make data.
prove your hypothesis is right.
become famous.
to compare a known to an unknown.
15
What is a dependent variable?
The variable that is most dependent.
The changed variable before the experiment.
A variable different in the control and experimental groups.
The outcome variable that is measured.
