Physical Science
Anything that takes up space.
What is matter?
All energy in an ecosystem comes from here.
What is the sun?
The process of water vapor turning into liquid water is called this:
What is condensation?
It takes approximately this amount of time for the Earth to orbit the sun
What is one year (365 1/4 days)?
This is the process that plants use to produce glucose and oxygen.
What is photosynthesis?
Term for a material that allows electricity to travel through it
What is a conductor?
This is the term for energy moving between organisms in an ecosystem.
What is a food chain?
If a rock could be described as having very small grains of sand in different layers, it would probably be this type of rock.
What is sedimentary?
It takes this long for the earth to make one rotation.
What is 24 hours?
In the water cycle, rain, snow, or sleet falling to the ground is a form of this.
What is precipitation?
This unit of matter is bigger than an atom and is usually a combination of two or more elements.
What is a molecule?
The term for an organism that breaks down matter in a food chain.
What is a decomposer?
The type of rock formed when hot lava cools.
What is igneous?
Michael observed a full moon in the sky on a Tuesday evening. Two weeks later he looked at the sky. The moon was now in this phase.
What is the new moon?
Molten rock that reaches Earth's surface
What is lava?
The term for when a liquid changes to a solid.
What is freezing?
The first level of any food chain consists of these.
What are primary producers?
These are frozen, slow-moving rivers of ice that can move about three feet per day down mountain valleys. As they travel, they scrape small particles off of rocks which later helps create new soil.
What is a glacier?
We have seasons on earth because the earth does this.
What is tilts on its axis?
In the engineering design process, the term used for the rough draft of a new technology being created.
What is a prototype?
This chemical has a much lower freezing and boiling point than water. When you add an object to it and can freeze the object solid in a matter of seconds.
What is liquid nitrogen?
When an organism changes something about their behavior or physical form to be better able to survive in their environment.
What is an adaptation?
When living things die and are buried underground for long periods of time, they can undergo chemical changes that turn them into this kind of fuel.
What are fossil fuels?
Recently the North pole had its last sunset for 86 days! It is now this season on the SOUTH pole.
What is winter?
The process of moving sediment by wind, water, or ice.
What is erosion?
