Experiments 101Everything you always knew you never
wanted to know about experiments…but need to learn anyway.
![Page 2: Experiments 101 Everything you always knew you never wanted to know about experiments…but need to learn anyway.](https://reader035.fdocuments.us/reader035/viewer/2022072113/56649f335503460f94c4fed9/html5/thumbnails/2.jpg)
In science we perform experiments in order to test a hypothesis.
![Page 3: Experiments 101 Everything you always knew you never wanted to know about experiments…but need to learn anyway.](https://reader035.fdocuments.us/reader035/viewer/2022072113/56649f335503460f94c4fed9/html5/thumbnails/3.jpg)
Effective, reliable experiments must
test ONLY one variable
include a control
be repeatable
test your hypothesis

Variables
Independent or Manipulated
This is the variable that you control or manipulate.

the type of paper for the paper airplane

Variables
Dependent or Responding
This is the variable you CANNOT control. It “depends” on the independent variable.

Variables
Dependent or Responding
This is the variable you CANNOT control. It “depends” on the independent variable.
You should only have ONE dependent variable in an experiement.
the distance the paper airplanes flew

Control
This is everything in the experiment that you have control
over.
Controls are used for comparison.
All variables in an experiment should be controlled (or the
same).

What did we control in the “Come Fly with
Me” lab?
![Page 11: Experiments 101 Everything you always knew you never wanted to know about experiments…but need to learn anyway.](https://reader035.fdocuments.us/reader035/viewer/2022072113/56649f335503460f94c4fed9/html5/thumbnails/11.jpg)
What did we control in the “Come Fly with
Me” lab?Size of paper
How we folded the planes
How we threw the planes
How we measured the distance

DataAll data should be recorded during the experiment.
Your analysis and conclusion should match your data.
DO NOT MAKE THINGS UP!!
The data you collect should be about your dependent variable.

The wind was blowing when we threw the notebook paper plane.
The man I interviewed said he felt sad when it rained.
The patient reported he had some dizziness after taking the pills.
