What is a manipulated variable? (aka independent variable)
An educated guess.
What is a hypothesis?
The energy of motion and movement.
What is kinetic energy?
What everything in our solar system is orbiting around.
What is the sun?
The variable that is different across your different groups.
What is manipulated variable? (aka independent variable)
After giving dogs Gatorade for a week, they all got sick. The dogs getting sick as a result of the gatorade is an example of this variable.
What is a responding variable? (aka dependent variable)
Something you notice using one of your five senses.
What is an observation?
The formula to calculate kinetic energy.
What is Ek = 1/2mv2
______ that has mass also has gravitational force.
What is everything?
Another name for "dependent" variable.
What is a responding variable?
The group that does not receive any treatment or manipulated variable. It is important to have in order to make comparisons.
