Scientific Method
Experiments begin when we observe something we want to know more about and we ask this.
question
We rolled marbles down a curved track. Marbles on the track that was lifted higher traveled_________.
faster
In a collision, energy is _______________ from one object to another.
transferred
the ability to do work
energy
energy that is in motion or working
kinetic
An educated guess about what will happen is called this.
hypothesis
When we compared a small marble to a large marble falling from the same height, we discovered that the marbles travel at the ________ _________.
same speed
When objects rub together they create this force, which causes energy to transfer from one object to the other.
friction
any push or pull that makes things move
force
energy moving from one object to another in a collision
energy transfer
We do this when we look closely at something to learn more about it.
observe
We designed a _________ _________ to protect a plastic egg from breaking during a collision.
safety harness
Angelina had more energy than Suzi when her bumper car hit Mylo's because she was going __________.
faster
stored energy waiting to be used
potential energy
one object bumping into another
collision
After we conduct an experiment, we form one of these based on our observations and data.
conclusion
What was observed during the cannonball contest to decide which brother had more energy?
the height of the splash
Our Play-doh experiment that resulted in flatter play-doh after a fall from the highest point, taught us that the higher the fall, the _________ _________ an object has.
more energy
the force that pulls things down
gravity
this force slows a moving object down and eventually makes it stop
friction
These are the limitations we have on a project, such as time, supplies, or sometimes cost.
constraints
What was observed that caused us to decide that Angelina had more energy than Suzi when they collided with Mylo?
Angelina caused Mylo's car to go 5 feet, and Suzi caused Mylo's car to go 2 feet.
What is the relationship described in the weight energy transfer law as explained by the brothers' cannonball contest?
The heavier the object is, the more energy it has.
the rate at which something is moving
speed
the study of the world around us and how it works
