The passing of traits from parents to offspring.
Heredity
200
The energy an object has because it is in motion.
Kinetic Energy
200
The measure of how tall a wave is. Increases when a sound gets louder.
Amplitude
200
Area around the magnet where magnetic forces are felt.
Magnetic Field
200
The amount of time it takes the earth to travel around the sun.
one year
200
A molecule that is made up of nucleic acids. Phosphate and sugar make up the outer part of this double helix while bases make up the center.
DNA
300
The energy an object has because of its position or shape.
Potential Energy
300
The number of waves that pass a point in a given amount of time.
Increases when the pitch of a sound increases
Frequency
300
A magnet that consists of a power source, a piece of iron, and a coil of wire carrying current electricity around the iron.
Electromagnet
300
The amount of time it takes the moon to revolve around the earth.

The alleles that you have for a trait vs. the physical appearance of the trait (two words).
Genotype vs. Phenotype
400
The variable that you measure during during an experiment.
Found on the Y axis
Dependent Variable
400
When a sound wave is reflected off a surface.
Echo
400
Groups of atoms that need to be aligned for a piece of iron to have magnetic properties.
Magnetic Domain
400
When the moons shadow covers the sun.
Solar eclipse
400
Describe the base pairing rules for DNA.

500
The variable that a scientist changes in an experiment (manipulated variable)
Found on the X axis
Independent Variable
500
What a sound wave travels through.
Solid Liquid or Gas
Medium
500
Describe a way that you could make an electromagnet more powerful.
Increase the voltage of the power source.
Increase the number of coils.
500
Describe a reason we have seasons.
Earth revolves around the sun.
The earth is tilted on its axis (23.5 degrees)
The sun is more focused where we live when the Northern hemisphere is tilted toward the sun (Summer).
The sun is less focused when the Northern hemisphere is tilted away from the sun (Winter).

Draw a Punnett Square for a parent that is heterozygous for red flowers crossed with a parent that is homozygous dominant for red flowers.
Red flowers dominant (R)
White flowers recessive (r)
