Scientific Method
100
When materials will not allow ANY light to come through
Opaque
100
What is the purpose of a simple machine?
to make work easier.
100
Which physical property will allow you to tell salt from sugar?
taste
100
If a ball is dropped, how does the energy change?
It goes from potential to kinetic
100
During this phase you use your sensed to gather information and form questions.
Observe and ask questions
200
Materials that allow SOME light to pass through
translucent
200
A lawn mower is a compound machine? True or False
True
200
Give an example of a physical change
Cutting an apple, painting a room, an ice cube melting
200
What happens to the molecules of a substance when it is heated?
They move around
200
During this step you write down the procedure to be followed, list equipment, and decide on a variable to be tested.
Plan an experiment
300
ALL light is allowed to pass through.
Transparent
300
What is friction?
A force that causes an object in motion to slow down or stop. You can slide across ice better than carpet because there is less friction.
300
How can you make 2 magnets repel (push away) from each other?
Hold the like poles near each other.
300
Since liquid water is hotter than solid water, which one has the most kinetic energy?
What is liquid water
300
You use charts, tables, graphs and reports to summarize and display data collected during this step.
Draw Conclusions and Communicate Results
400
The correct order of visible light
Red, Orange, Yellow, Green, Blue, Indigo, Violet
400
Which state of matter has definite volume, but not definite shape?
liquid
400
Is ice melting a physical or chemical change?
Physical
400
Compare the kinetic energy of steam to ice.
Steam has more kinetic energy because it is hotter
400
During this step you observe and write down observations as you follow the procedure that was written.
Conduct experiment
500
When light reflects it bounces back and spreads out. What is the spreading out of light called?
Scattering
500
Give an example of matter
people, desks, air, dirt, water, etc.
500
Which physical property allows mirrors to reflect lots of light?
They are smooth and shiny
500
Explain why bubbles form when water is heated to 212 degrees.
The more heat that is applied, the more the molecules move. the bubble are the result of the molecules moving very quickly.
500
During this step you write a statement that can be tested.
