States of Matter
According to Kinetic Theory, do atoms move faster in a solid or a gas?
Gas
True or False: Matter is made of tiny particles called atoms.
TRUE
This force pulls all objects with mass toward each other.
Gravity
This type of energy from the Sun warms the Earth's surface.
Radiation
How many days does it take for Earth to complete one revolution?
365.25 days or 365
These are the different shapes of the Moon we see from Earth.
Moon phases
These are the living parts of an ecosystem.
Biotic factors
This diagram shows how energy moves from one organism to another.
Food chain/web.
True or False: Human activities can only have negative impacts on nature.
False
What must be added to a liquid to increase the movement of atoms and cause boiling?
Heat or Thermal Energy
Scientists use these to study atoms because they are too small to see.
Models / High Powered Microscopes
A magnet pulling a paperclip without touching it is a force at a __________ .
Distance
When the Sun's radiation hits the Earth, it is _______ to warm the atmosphere.
Absorbed
The tilt of Earth’s ____ is the primary reason we have seasons.
Axis
Earth's ___________ on its axis is what causes night and day.
rotation
Sunlight, water, and rocks are examples of these non-living factors.
Abiotic factors
In an ecosystem, matter is _______ over and over again.
Cycled
When two animals fight for the same food, it is called __________.
Competition
Besides temperature, a change in this can force a gas to become a liquid.
Pressure
In which state of matter are atoms vibrating in a fixed, rigid position?
Solid
This type of force can push (repel) or pull (attract) certain metals.
Magnetic Force
What would happen to Earth's surface temperature if it stopped absorbing radiation?
It would drop drastically/become freezing.
During summer in the Northern Hemisphere, is that half of Earth tilted toward or away from the Sun?
Toward
This event occurs when the Moon passes into the Earth's shadow.
Lunar Eclipse
Interdependence means that organisms rely on their __________ to survive.
Environment
These organisms get their energy by breaking down dead matter.
Decomposers
Give one example of a human activity that increases competition for resources.
Deforestation/Over-fishing
When atoms in a liquid slow down enough to form a solid, it is called this.
Freezing
True or False: Atoms are the building blocks of all matter.
True
If you increase the distance between two magnets, does the force get stronger or weaker?
Weaker
How does the Sun's energy reach Earth through the vacuum of space?
Radiation Waves
This term describes the variation in the length of a day throughout the year.
Seasonal variations
Groups of stars that appear to move across the sky in patterns are called what?
Constellations
How does an abiotic factor, like a drought, affect the biotic factors in a pond?
Biotic factors may adapt, migrate, or die
Where does the energy in a food web originally come from?
The Sun
How can humans positively impact the survival of a changing species?
Conservation/laws
Explain how Kinetic Theory (movement of molecules) describes the difference between a liquid and a gas.
Gas atoms move faster, spread out. Liquid atoms move slower than gas atoms, semi-spread out.
Name 2 characteristics for each of the states of matter:
Solid, Liquid, Gas
Solid: atoms tightly packed, vibrating in place, has it's own shape
Liquid: atoms spaced apart, takes the shape of whatever container it is in
Gas: atoms very spaced apart, moving quickly, takes shape of whatever container it is in
Predict what happens to a compass needle when a strong magnet is placed near it.
Needle will rotate to align with the magnets field.
Use ratios to explain why planets further from the sun have longer "years."
Further planets have a larger orbital circumference to travel.
If the Earth had zero tilt, how would that affect our seasons?
We would have no seasons or;
We would have one constant type of weather/climate.
Explain why we always see the same side of the Moon from Earth.
The Moon rotates and revolves at the same rate.
Construct an argument for why energy decreases as it moves up the food chain.
Because energy is lost as heat at each level
Create a model showing how carbon moves from the air to a plant to an animal.
CO2 (air) --> Photosynthesis (plant) --> Consumption (animal)
Predict how a species might change over time if its environment becomes much colder.
Adaptations like thicker fur or migration
