In the engineering design process, this step comes after designing a prototype
What is testing the prototype?
200
This process of the water cycle turns liquid water into water vapor (not clouds!).
What is evaporation
200
This biological molecule controls the traits you inherit from your parents
What is DNA (deoxyribonucleic acid)?
200
This happens when a wave bounces off a surface

In order to have this type of trait, you must have two of this type of gene.
What is recessive?
300
This happens when a wave passes through a surface and is bent
What is refraction
300
The type of change that happens when water boils
What is a physical change?
400
This type of system allows matter an energy to move in and move out of the system
What is an open system?
400
In this process of the water cycle water on the surface of the Earth sinks into the ground.
What is infiltration (or percolation)
400
This is a segment of DNA that controls a specific trait
What is a gene?
400
This property of a sound wave determines how loud or quiet the sound is
What is amplitude?
400
The state of matter where particles can slide past each other but not move away.
What is liquid?
500
This type of system allows energy to enter and leave, but not matter
What is a closed system?
500
In this process of the water cycle, water is released from the leaves of plants as water vapor.
What is transpiration?
500
This is a change in the sequence of DNA that produces a new trait
What is a mutation?
500
This characteristic of waves is the number of waves that pass a point in a given amount of time
