Forces
This is a push or pull on an object.
What is a change in an objects position?
Motion
What is the ability to cause change or do work?
Energy
This is a testable prediction about what might happen in an experiment.
Hypothesis
Plants are producers because they....
make their own food
This kind of force moves an object away from you.
Push
What is the amount of matter in an object?
Mass
What is energy an object has because it is moving?
Kinetic Energy
This is the variable that "I" change on purpose.
Independent Variable
This occurs when water vapor changes to a liquid.
Condensation
This kind of force moves an object towards you.
Pull
What is the invisible pulling force that puts our feet on the ground and stops us from floating in space?
Gravity
What is stored energy called?
Potential energy
This the "data" that scientist observe and collect.
Dependent Variable
The average weather pattern of a region (place) over time is called....
Climate
This force happens when surfaces rub together and resist motion.
Friction
Speed
This happens when a force moves an object over a distance
Work
These are the parts of the experiment that are kept the same.
Constants
The function (job) of this plant part is to move food, water and nutrients throughout the plant.
Maya uses a spring scale to measure how hard she has to pull a wagon. The scale reads six what unit is the force measured in?
Newtons (N)
Two cars are pushed with the same force. One car is empty and the other is loaded with blocks. Which car will have the bigger change in motion from the push?
The empty car
A ball rests at the top of the ramp and then rolls down. What type of energy does it have at the top and what type of energy does it gain as it rolls?
Potential at the top and Kinetic as it rolls
A student tests whether the height of the ramp changes how far a toy car travels. The student uses the same car, ramp surface, and starting point each time what is the independent variable?
The height of the ramp
In which state of matter does water have a definite shape and volume?
Solid
