True or false
A push/pull is a force.
True
We flicked cars and measured the distance they traveled.
Car Push Investigation
The object was dropped and glided to the floor.
gravity
True or False: A fair test includes only one trial.
False: A fair test includes more than one trial.
What is a hypothesis?
A hypothesis is a prediction of what will happen in the experiment.
Weight is one factor that affects the distance and speed an object travels.
True
We used ramps to test the speed and distance that two balls traveled.
Downhill Racer Investigation
The object repelled from the other object.
Magnetism
Group 1 measured in centimeters and group 2 measured in meters. At the end of the experiment, the group 1 converted their answers to meters.
Is this a fair test? Why or why not?
Yes, because in the end, both are in the same measurements (meters).
Observations are.....
a. what you see
b. what you hear
c. interpretations of what you see and hear
d. a and b
d. a and b
Observations are what you see and hear directly. They are not interpretations!
Air resistance effects the rate at which a feather falls when dropped.
True
We dropped objects from the same height.
The Sky is Falling
My dad helped my swing go back and forth by ______ the swing.
pushing; push
There were three trials for one object and two for another because they ran out of time.
What should they do to make it a fair test?
a. it is fine because they ran out of time
b. do the third trial for the other object the next day
b. The trial numbers need to be the same for a fair test.
electrons
Density of an object does not affect the distance or speed of that object.
False
We investigated with magnets in stations.
Magnetism Investigation
We played in a Tug of War game.
pull
What are the positively charged particles of an atom called?
protons
What is one example of a force you have used or seen in real life?
Ex. magnets, push a swing, pull your dog on a leash, etc.
We made footballs and tested using different angles to flick them at.
Paper Football Investigation
True or False: In static electricity, the protons are the particles that move from one object to another.
False: Only the electrons move from one object to another.
What is a constant?
A variable or factor in the experiment that stays the same (constant) throughout the entire experiment.
True or False: Density and mass both mean the same thing.
False: Density is how the molecules are packed.; Mass is the weight.
