Required to conduct a controlled experiment.
What is control all of the variables except for the one you are testing.
100
To control variables means to
What is change one thing at a time?
100
Factors or conditions that can change and might affect the experiment
What are variables?
100
Kellen’s grandfather clock is running too slowly! What could he do to the pendulum in her clock so that it will keep time?
What is shorten the pendulum?
100
I wanted to know what would happen in the swinger experiment if I changed the way I made the pendulum. Instead of using string I used yarn to make the standard 38 cm long. I used a gummy bar at the end for the pendulum bob. Then I counted how many times the pendulum swung back and forth in 15 seconds. Did I do a good job controlling the variables? Why or why not?
What is no, because I changed more than one variable - the material used for the pendulum and the pendulum bob?
200
What does a scientist do following his or her experiment?
What is observe the results? OR What is report the findings?
200
The maximum amount a container can hold
What is capacity
200
An experiment in which one, and only one, variable is changed in order to assess its effect
What is a controlled experiment?
200
Hannah set up a flipper system to investigate what effect the angle of launch has on how far she can flip an aluminum ball. Which of these angles would result in the greatest distance? 20 degrees or 40 degrees?
What is 40 degrees?
200
I think light melts ice cream. I put one scoop of ice cream outside over night. I put one scoop of ice cream in the kitchen under a lamp. The one inside melted. Light must melt ice cream! Is this a good experiment? Why or why not?
What is no, the temperature was not the same indoors as it was outside, so more than one variable was different.
300
This gives an airplane most of its lift.
What are wings?
300
Daily Double!
300
The basic procedure used in a controlled experiment, before changing any of the variables
What is a standard?
300
Describe a system.
What is a set of objects working together.
300
Three boys wanted to see who could skip a rock the farthest. Each boy brought his favorite type of rock to the park. Boy 1's rock had a mass of 7 g, Boy 2's rock had a mass of 10 g, and Boy 3's had a mass of 5 g. They placed a stone on the ground to mark the point from which they would skip rocks. Boy 1 took two steps when he skipped his rock. Boy 2 stood still when he skipped his rock. Boy 3 got a running start and skipped his rock. Do you think the boys have done a good job of controlling the variables? Why or why not?
What is no, they should control all variables except for who is skipping the rock, so everyone should skip the same kind mass rock, and everyone should stand, take two steps, or run up to the stone to throw.
400
The pilot that first flew faster than the speed of sound, he reached "Mach 1."
Who is Chuck Yeager?
400
The _________________________ the string, the fewer the swings the pendulum will make in 10 seconds. The _________________________ the string, the greater the number of swings a pendulum will make in 10 seconds.
What is longer, what is shorter?
400
An "educated guess" to a scientific question
What is a hypothesis?
400
Name two variables that had an effect on the FOSS planes.
What are number of winds, mass, or length of rubber band?
400

What is time of day
500
This invention allowed planes to fly much faster
What is a jet engine?

What is lighter, farther?
