1. What is the definition of experiment?
An investigation we do to see how variables affect outcomes.

2. What is the definition of controlled experiment?
When only one variable is changed in an experiment.

3. What is the definition of variable?
Something that can be added or changed that changes the outcome
of the experiment.

6. What is the definition of standard wind?
Calm, steady wind that doesn’t cause any problems during a flight.

7. What is the definition of pre-flight information?
When the pilot checks the
oil, gas, engine, wings, weather, wind speed, wind direction, and the route he is going to take before taking off.

8. What is the definition of post-flight information?
The pilot refuels the plane and takes care of all the information from pre-flight in order for the plane to be
ready to fly again.

Type of rubber band, Length of string, Weight on the airplane

21. What was the one variable we tested in the life boat
experiment?
Capacity

24. Why is it important to know all the parts of a system before you can
predict what will happen?
If you don’t know all the parts of a system you will not know what the outcome is supposed to be so you
won’t know if your system is working correctly or not.

25. Review concrete graphs, pictographs, and coordinate graphs.
I will give you data to plot on each of these graphs. This is very similar to page 12 of your variables journal.
