Outer Space: Solar System/ Earth-Sun-Moon
How long does it take Earth to revolve around the Sun?
1 year: 365 days
What did Darwin notice about the finches he studied?
Each species of finch had a distinct beak that was well suited to the finch’s diet.
Does water have higher or lower potential energy at the top of the hill, all else being equal?
The potential energy of the water at the top of the hill will be greater.
A wave in which the particles move along a path that is parallel to a wave's direction is called a...
longitudinal wave
What is net force on an object that is at rest
0
What do circumpolar stars travel around?
Earth's poles (N or S)
what is a gene
A gene is made of DNA and contains the instructions for building proteins.
Name the six dimensions of wellness.
Spiritual, Emotional, Physical, Environmental, Intellectual, Social
T/F: Xrays carry more energy than visible light waves.
True
What do you need to calculate the average acceleration of an object.
velocity and time
How often does the Earth take to rotate on its axis?
24 hours
Yellow beetles are better camouflaged than green ones from predators. How do you predict beetle color in this population will evolve over time?
Yellow beetles have a greater chance of surviving and reproducing and will become more common in the population.
Define coping mechanism.
Strategies people can use to manage difficult emotions.
A wave cycle is
one complete motion of the repeating pattern in a wave.
What is Newton’s third law of motion?
For every action, there is an opposite but equal reaction.
T/F: When the light hits Earth at a 90 degree angle, the intensity of the light is low resulting in cooler temperatures.
False.
T/F: A harmful mutation increases an organism's chance of survival.
False.
The pot of water has started boiling. What type of energy transformation takes place when this happens?
Thermal (heat) to kinetic.
When a wave bends as it is transmitted from one medium into another medium, it is called...
Refraction
Sarah throws a pencil in the air. It reaches the highest point of its upward motion, turns, and falls back to the ground. At which point was the pencil accelerating without changing speed?
at the highest point
List the planets in order
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
T/F: Rock strata from the early Cambrian Period provide evidence of a huge number of different kinds of animal life, whereas rock strata from the late Precambrian Era provide evidence of only a small number of different kinds of animals. This is due to an increase in biodiversity in the Cambrian Period.
True.
Why does 10 g of steam at 100°C has more thermal energy than 10 g of water at 100°C?
because its particles can move more freely
Definition: When a wave transfers energy to the medium it is passing through.
absorption
Newton’s second law of motion states that an object’s acceleration is equal to
the net force on an object divided by its mass.
