Variables
What are controlled variables
Variables that stay the same throughout every experiment
What was the standard pendulum length
35 cm
What are the two kinds of tides
Spring tides and Neap tides
Does the mass or weight change when you travel to the moon, Jupiter, Mars, etc.
Weight
mass stays the same no matter where you go
What is gravity
The force that pulls you towards the planet you are on
What is an Independent variable
The one variable that changes throughout experiments
What was the standard pendulum release position
90 degrees
Which type of tide is when the low tides are lower and high tides are higher
Spring tide
What do you use to measure mass
What is a dependant variable
The result of the experiment using the independent variable
What was the range of pendulum lengths we made
13 cm - 200 cm
Which type of tide is when low tides are higher and high tides are lower
Neap tide
What do you use to measure weight
A scale
What is a variable
Anything in an experiment that can be changed
What was the standard pendulum's number of complete swings
12 complete swings
How does the sun affect tides
It creates Spring and Neap tides when it, the Earth, and The moon are aligned
What determines the weight of an object on Earth
Earth's gravitational pull on the object
What are the three independent variables that we changed during the pendulum experiment
Mass, Release Position, and Length
What independent variable changed the results of the experiments
Pendulum length
What are the four moon phases that cause Spring and Neap tides
Full moon, New moon, First Quater, and Last Quarter
