Scientific Method
Which personal trait do scientists mainly depend upon when they design an experiment?
Creativity
These are the parts of an experiment that are kept the same to ensure a fair test.
Control Variables
What is mass?
The amount of "stuff" or matter in an object
The force of gravity's pull on an object's mass, and it can change depending on the gravitational field.
This is the most important rule you should follow before starting any lab experiment.
Always follow the teacher's instructions and read the procedure.
How does a scientist increase the accuracy of their experiment?
Repetition
This is the variable that the scientist intentionally changes or tests in an experiment.
Independent variable
This is a physical property that doesn't change no matter where it is in the universe.
Mass
This unit measures weight and represents the force of gravity.
Newtons
What does a "flammable" hazard symbol on a chemical container indicate?
The substance can easily catch fire.
What personal trait is most important for a scientist to have while collecting data
Objective or unbias
Dependent variable
In physics, this unit is used to measure mass.
Kilograms or grams
What kind of scale did we use to measure weight?
Spring Scale
How should you behave when you a doing a lab?
You should be calm and paying attention to what you are doing.
How does a scientist gain confidence in the results of their experiment?
Replication
A student drops a golf ball from different heights to see how high it bounces. What is the independent variable?
The height from which the ball is dropped
Name the types of scales used to measure mass.
Balance Scales (pan balance scale and triple beam balance scale)
Why does an astronaut weigh less on the Moon than on Earth?
Because the Moon's gravity is weaker than Earth's.
What should you do if an accident or emergency occurs in the lab?
Notify your teacher immediately
What would be the next step a scientist will take after their data does not support their hypothesis?
Generate further questions and new experiments.
In an experiment testing if a plant grows taller with more fertilizer, the amount of fertilizer is the IV, and the plant's height is the DV. What is the control variable?
the amount of water and light the plants receive
If an object's mass doubles, what happens to its weight?
It increases
On this planet, a person would have the greatest weight because of its immense gravitational pull. (we calculated this in the lab)
Jupiter
If you get chemicals in your eyes, what safety tool should you use immediately?
Eyewash Station
