Matter
Name the three main states of matter.
Solid, Liquid, and Gas
Name the four Earth systems.
Geosphere
Hydrosphere
Atmosphere
Biosphere
The source of all energy in an ecosystem is...
The Sun
Earth rotates on its ___________ once every _______________ hours.
Earth rotates on its axis once every 24 hours.
Define condensation
When water vapor cools and turns into liquid.
Matter is...?
Anything with mass that takes up space
All living things are part of the...
Biosphere
The flow of energy.
Why does the sun look larger to us on Earth than other stars?
It is the closest star to Earth.
Where in a plant does photosynthesis take place?
In green leaves.
According to the Law of Conservation of Matter, Matter is never _____________ nor _________________.
Destroyed nor created.
Which two earth systems are interacting?
Plants take in carbon dioxide and release oxygen through the process of photosynthesis.
Atmosphere and Biosphere
Define producer, consumer, and decomposer.
Producer- creates its own food/energy by using sunlight
Consumer- gets energy by eating other organisms
Decomposer- breaks down dead/decaying plant and animal matter.
Why do objects like the sun appear to move across the sky?
Earth is rotating on its axis.
Which type of circuit has multiple paths for electrical current to flow allowing for parts of the circuit to continue working if part of it fails?
Parallel Circuit
What is the difference between a solution and a mixture?
A mixture is a combination of two or more substances that retain their original properties. A solution is a special type of mixture where one material dissolves into another.
Water from a river causes weathering and erosion to the riverbank.
Geosphere and Hydrosphere
Name the three types of consumers and what types of organisms they eat.
Carnivore- other animals
Herbivore- plants
Omnivore- both plans and other animals
Describe how and why shadows change throughout the day?
In the morning and evening shadows are longer because the sun is lower in the sky as it "rises" and "sets". In the middle of the day shadows will be shortest because the sun is more directly overhead (at its highest point in the sky).
These help plants and animals survive in their environments. They can be learned or inherited. They can be physical or behavioral.
Adaptations
What is the difference between a physical and chemical change?
In a physical change matter changes form but does not produce a new substance or alter the chemical identity of the material. A chemical change occurs after a chemical reaction and a new substance is produced. The matter changes chemical make up- not just form.
What system includes all solid parts of Earth from the surface down to Earth's core?
The Geosphere
Fill in with the materials required for and the products of photosynthesis.
____ + _____ + _____ = _____ + _____
Sunlight + Carbon Dioxide + Water = Sugar (glucose) + Oxygen
What causes Earth to experience seasons?
Earth is tilted on an axis. As it revolves around the sun different parts of the Earth receive direct or indirect sunlight.
What is the different between opaque, translucent and transparent?
Translucent- some light passes through
Transparent- all light passes through
