Variables
What are controlled variables
Controlled variables are the variables that stay the same throughout every experiment
What was the standard pendulum length
35 cm
What are the two types of tides
Spring and Neap Tides
Does your mass or weight change when you travel to the moon
Weight
What is gravity
The force that pulls an object toward the planet that it's on
What is an independent variable
An independent variable is the one thing you change throughout experiments
What was the standard pendulum release position
90 degrees
What are the four moon phases that affect tides
Full moon, New moon, First Quarter, and Last Quarter
How do you measure weight
A scale
What is a dependant variable
The result of an experiment
What was the range of pendulum lengths we used
13 cm - 200 cm
How does the sun affect tides
it creates Spring and Neap tides when it, the moon, and the Earth are aligned
How do you measure mass
A balance
What were the three independent variables we tested during the pendulum experiment
Mass, Release Position, and Pendulum Length
What independent variable(s) changed the results of the pendulum experiments
Pendulum Length
What is the tide called when high tides are higher and low tides are lower
Spring tides
What determines what an object's weight is on Earth
Earth's gravitational pull on the object
What is a variable
Anything in an experiment that can be changed
How many trials did we do per variable
10 trials
What is the tide called when the high tides are lower and the low tides are higher
Neap tides
