Matter & Mixtures
This law states that the total weight of matter stays the same even if it is heated, cooled, or mixed.
What is the law of Conservation of Matter?
This is the original source of energy for nearly all food chains on Earth.
What is the sun?
This "sphere" includes all the water on Earth, including oceans, rivers, and glaciers.
What is the hydrosphere?
The sun appears much larger and brighter than other stars because of this factor.
What is distance (or proximity to Earth)?
Light bouncing off an object.
What is a reflection?
This type of mixture is formed when one substance (like salt) dissolves completely into another (like water).
What is a solution?
These organisms, such as fungi and bacteria, break down dead matter and return nutrients to the soil.
What are decomposers?
Most of the Earth's water (about 97%) is found here and is not drinkable for humans.
What are the oceans?
This movement of Earth around the Sun takes about 365 days causes the seasons.
What is revolution (or orbiting)?
The path one object takes around another object in space.
What is an orbit?
This tool uses a physical property to separate iron fillings from a pile of sand.
What is a magnet?
In a food web, the arrows represent the flow of this from one organism to another.
What is energy?
When plants (biosphere) pull water from the soil (geosphere) and release it into the air, they are interacting with this "sphere".
What is the atmosphere?
If a shadow is at its shortest point of the day, the Sun is likely in this position in the sky.
What is directly overhead? (high in the sky).
A force that causes a spring scale to show the weight of an object.
What is gravity?
To prove that matter is made of these, scientists use models because they are too small to be seen.
What are particles (or atoms/molecules)?
Animals use the energy from food for these four things: body repair, growth, motion, and _____________.
What is maintaining body warmth?
This process describes how water moves from the Earth's surface into the atmosphere and back again.
What is the water cycle?
These groups of stars appear to move across the sky at night because of Earth's rotation.
What are constellations?
A characteristic that helps an organism survive.
What is an adaptation?
DAILY DOUBLE
If you mix 10g of sugar with 100g of water, the final weight of the solution will be exactly this.
What is 110g? (weight is conserved).
This model shows multiple overlapping food chains and how matter cycles through an entire ecosystem.
What is a food web?
Humans can protect Earth's resources through this "C" word, which means using resources wisely.
What is conservation?
Earth rotates on its axis once every 24 hours, which creates this daily cycle.
What is the day/night cycle?
Matter is made of:
a. energy
b. particles too small to be seen
c. mostly air
What are particles too small to be seen?
