Day Two/ Day 3 (this part may take two days)

Begin the day by reflecting upon what you observed and learned from your first set of paper airplanes (what made the paper airplanes fly well, what made them not fly well) with the people around you.

Today we will show the importance of testing for one variable at a time.

Our investigation will be over Drag vs Weight.

The question of the day is: “Will the number of paperclips on a paper airplane affect the distance of the flight?”

Journal Entry:

Is this a testable question? Make predictions in your notebook about the number of paperclips and how it/they will affect the distance of the flight.

Once you have written in your journal share your predictions within your group.

Next, identify the manipulated, responding, and constant variables.

Manipulated Variable-
Responding Variable-
Constant Variables-

Take this quiz to check your understanding of the different types of variables.

Testing:

Step 1: Build

Make a new airplane you can try a new design or the same design from Day 1.

Step 2: Test

Test the airplane, make sure that starting position and thrust are the same for all 3 flights.

Step 3: Record Data

Record your data in a table in your journal.

Test flight	paper clip total	flight distance	flight time	observations

Step 4: Reflections

Reflect upon your observations in a conclusion. Record any "I wonder questions" that you would like to answer through more investigation.
