Teacher’s Notes, page 1
• Background:– Students should already know how to identify
and use observation, inference, and prediction.– Students should be familiar with Cornell note
strategies.• This introductory lesson will be
accompanied by a laboratory experiment and data analysis.

• Action Steps incorporated into this lesson:– Identification of critical-input experiences– Presentation of information in small chunks
with room for student input– Student-written conclusion (in Cornell format)– Student reflection of learning

What is Scientific Inquiry?• It is the process of using
observations, inferences, predictions and experiments to learn about the world
• It is an ongoing process of discovery• It is used in all types of science, but
also in other areas, and even regular daily life!
![Page 14: The Helicopter Hypothesis](https://reader035.vdocuments.site/reader035/viewer/2022062323/56815d98550346895dcbb9f4/html5/thumbnails/14.jpg)
Example: Scientific InquiryUh oh! I turn on my radio, but no music
comes out.
Maybe the radio is unplugged?
If the radio is unplugged, then plugging it in will start the music.
I’ll check and see if the plug is plugged
into the wall.
Yep, the plug is plugged in.
The plug isn’t my problem.
Something else must be wrong.

What is a Hypothesis?• It is a prediction • It is almost always based on
observations and inferences• It is testable• It is my best guess of what will
happen
![Page 18: The Helicopter Hypothesis](https://reader035.vdocuments.site/reader035/viewer/2022062323/56815d98550346895dcbb9f4/html5/thumbnails/18.jpg)

What is a Control Group?• It is the unchanged (“normal”)
stuff in an experiment where I am testing different conditions
• It is something to which I can compare my test results
• It’s sometimes just called a control
Control =Comparison

What is an Independent Variable?
• It is the condition I change in an experiment
• I change it because I want to see what will happen
• I should change only one thing at a time
• I’m in charge of it!Independent Variable =
I change it
![Page 22: The Helicopter Hypothesis](https://reader035.vdocuments.site/reader035/viewer/2022062323/56815d98550346895dcbb9f4/html5/thumbnails/22.jpg)

What is a Dependent Variable?
• It is the data I collect• It is the observation I make after
testing my independent variable• It is the result of my experiment• It depends on what I changed
Dependent Variable =Data that Depends

What is an Uncontrolled Variable?
• It is a source of error• It is an unexpected mistake or
event in my experiment• It may be unavoidable• It may make my data unreliable• It is generally unwanted!
Uncontrolled Variable =Unexpected, Unreliable

The Helicopter Hypothesis• To practice using
all these parts of scientific inquiry, you will build and test paper helicopters
• Your goal is to figure out what will make them stay in the air the longest

The Helicopter Hypothesis• In your next
lessons, you will perform the experiment and examine your data
• You’ll learn more about scientific inquiry by really using it!
