May the Force Be With You
This law states that an object at rest will stay at rest unless acted upon by an unbalanced force.
What is Newton’s First Law (Inertia)?
This is the term for an organism's physical appearance, such as blue eyes or brown fur.
What is a phenotype?
Earth experiences these because its axis is tilted as it revolves around the Sun.
What are seasons?
He is the scientist famous for studying finches and proposing the theory of natural selection.
Who is Charles Darwin?
Sound waves require this—a solid, liquid, or gas—in order to travel.
What is a medium?
This is the unit used by scientists to measure force.
What are Newtons?
This type of reproduction requires two parents and results in high genetic diversity.
What is sexual reproduction?
This lunar phase occurs when the Moon is positioned directly between the Earth and the Sun.
What is a New Moon?
These are the remains or traces of organisms that lived in the past.
What are fossils?
This is the distance between one wave crest and the very next crest.
What is wavelength?
This force always acts in the opposite direction of a moving object.
What is friction?
This term describes a genotype with two different alleles, like "Bb."
What is heterozygous?
These extra-strong tides occur when the Sun, Moon, and Earth are all aligned in a straight line.
What are Spring Tides?
This happens to a species when it cannot adapt to rapid changes in its environment.
What is extinction?
This type of signal is sent as a series of 0s and 1s, making it more reliable than analog.
What is a digital signal?
This is the specific type of energy an object has because it is in motion.
What is kinetic energy?
If two heterozygous parents (Bb) have an offspring, this is the percentage chance the child will show the recessive trait.
What is 25%?
This is the term for the 24-hour cycle of Earth spinning on its axis.
What is rotation?
These are structures, like the human tailbone, that have lost their original function through evolution.
What are vestigial structures?
This phenomenon causes light to bend when it moves from one medium to another.
What is refraction?
Doubling this variable in the formula p=mv will result in doubling the object's momentum.
What is mass (or velocity)?
This is a permanent change in the DNA sequence that can be beneficial, harmful, or neutral to an organism.
What is a mutation?
During this specific event, the Moon passes directly into the Earth's shadow.
What is a lunar eclipse?
This process occurs when humans, rather than nature, choose which organisms will breed.
What is artificial selection (or selective breeding)?
These are waves where the particles move back and forth parallel to the direction the wave travels.
What are longitudinal waves?
