What is time of day
100
Define variable.
What is anything that can be changed in an experiment that may affect the outcome.
100
How many variables do you change in a controlled experiment?
What is one at a time.
200
Describe the catapult system that would result in the greatest height.
Length of Flipstick: 0cm-1cm Angle: 0-10 degrees Projectile: Small
200
Describe the parts of the pendulum system.
What is the string, the paperclip, the penny, the masking tape, and the pencil.
200
Define outcome.
What is the results of an experiment. It must be MEASURABLE!
200
What does it mean to analyze and interpret data?
To analyze data is to look at it closely. To interpret data is to figure out what the data is telling you.
300
What are the parts of the catapult system?
What are the base, angle, flipstick, and projectile.
300
If a pendulum in a grandfather clock is running too slowly, what can be done so that it will keep time?
What is shorten the pendulum
300
Define system.
What is a group of different parts, working together to accomplish a task.
300
What is a catapult?
A catapult is a lever arm that is loaded with energy. When the energy is released, any object resting on the end of the lever is hurled into the air.
400
What are the possible variables and outcomes for the catapult investigations?
Variables: length of the flipstick, angle, projectile type, location of projectile, and depression Outcomes: height and distance
400
Explain the relationship between the length of the strings and the number of cycles a pendulum makes in 10 seconds.
What is as the length increases the number of cycles decreases, and as the length decreases the number of cycles increases!
400
Define hypothesis.
What is an educated guess based on background information.
400
What is a pendulum?
A pendulum is any mass suspended on a string, rope, or other arm that is free to pivot from an anchor point.
