The measure of the distance an object travels in a certain length of time is the object's
The measure of the distance an object travels in a certain length of time is the object's speed. Speed describes how fast the object is moving.

After doing research on plants and fertilizers, a 5th grade science class states the hypothesis for their experiment; "If a plant receives fertilizer, then it will grow to be bigger than a plant that does not receive fertilizer."
What is the independent variable and dependent variable?
IV-Fertilizer
DV-plant growth
A boulder that is resting on the top of a cliff slips over the edge and accelerates towards the ground. As the rock falls, the amount of kinetic energy
As the rock falls, the amount of kinetic energy increases. Kinetic energy is energy of motion, and potential energy is transformed to kinetic energy as the rock accelerates toward the ground.
The surface of the Earth changes from processes such as erosion. Give an example of these changes to Earth’s surface due to erosion?
the wind picking up dust and carrying it
Water carrying sediment
movement of sediment
What does the scientific name consist of
written in Latin, it includes the genus name followed by the species name
What name is given to a set of organs that work together to perform a specific function?
system

A)stop moving.
B)move in unpredictable patterns.
C)move in the same direction as the stronger force.
D)move in the direction opposite the stronger force.
C)move in the same direction as the stronger force.

D)The Earth’s magnetic field is generated by a conducting fluid in its core.
D)The Earth’s magnetic field is generated by a conducting fluid in its core.
A scientific theory summarizes a hypothesis or group of hypotheses that have been supported with repeated testing.
