Matter and Energy
What is conductivity?
The major source of energy that powers the movement of water throughout the environment
What is the sun?
Which organisms make energy from light (photosynthesis)?
What is a producer? Ex - plant, phytoplankton
A special type of mixture in which a substance dissolves into another.
What is a solution?
Which state of matter does a gas change to when it is cooled?
What is a liquid?
This describes the next moon phase after a new moon.
What is a waxing crescent?
Name two landforms formed by DEPOSITION
What is a DELTA and a sand DUNE?
In a food web, which type of organism eats producers?
What is a consumer?
What is...
Examples: Biotic-biotic: bees pollinate flowers and flowers provide nectar
biotic-abiotic: rainfall is absorbed by the roots of the plant and sunlight is used for photosynthesis in the leaves of the plant
A beaker contains a mixture of sand, salt, gravel and iron fillings. Which substances are not soluble in water?
What is sand, gravel and iron fillings?
Salt is soluble.
The Sun appears to change position, shadows change position, and we experience night and day as a result of ...
What is Earth's rotation?
To form fossil fuels you need these things...
What are time, pressure/compaction, and organic matter (prehistoric marine life or plants)
Tundra animals have adaptations such as thick coats that allow them to survive in the vast tundra. Why would they need this?
What is to insulate from the cold tundra temperatures and wind?
The act of resistance on a moving object
What is friction
Students experiment with heating water to evaporate it. The teacher instructs them to wear rubber gloves because the gloves are...
What are insulators? Insulators do not allow thermal energy to flow through.
DOUBLE JEOPARDY:
The sun appears to move across the sky as the earth rotates on its axis. Describe the shadow as the sun is setting including its direction and size.
What is long and stretching toward the East?
What is the difference between a V-shaped valley and a U-shaped valley?
What is "A V-shaped valley is formed by a riVer and is also known as a canyon. A U-shaped valley is formed by a glacier/ice and is wider."
Explain a structure that would help an organism during a drought.
Possible answers: What are waxy leaves, spines on a cactus, or shallow wide roots?
What is a decomposer?
What is a type of organism that breaks down dead plants and animals?
Examples include bacteria, mold, mushrooms, earthworms, and fungi.
Which TWO properties of matter change when salt or sugar dissolve into water?
What is size and taste? The salt and sugar will get smaller in size and the water will change taste.
*The color of the water should not change when the substance has dissolved - it should be clear. The mass of each will remain the same, but the solution will combine both masses.
What causes the change in seasons?
What is Earth's tilt and orbit around the Sun (Revolution)?
Name and describe the steps in sedimentary rock formation
What is weathering (breaking rocks into sediments), erosion (sediments carried to a new location), deposition (sediments deposited in new location), compaction (pressure packs the layers together), and cementation (minerals harden/glued into new rock).
Describe how oxygen (matter) is cycled through an ecosystem.
What is - Producers like plants release oxygen when they go through photosynthesis. Next, animals and other organisms take in and use the oxygen to survive.
Explain the water cycle and what causes it.
What is the cycling of water: The sun's thermal energy warms water the ocean and other bodies of water, causing evaporation (turning liquid water into water vapor/gas). Then, as the water vapor cools, it condenses into clouds and precipitation can fall, like rain or snow. The precipitation then runs off (runoff) and collects into bodies of water, and the process continues.
