Force in Motion
What force pulls objects toward the center of the Earth?
What is gravity.
What state of matter keeps its shape and volume?
What is a solid.
What type of heat transfer comes from the sun or putting your hands over a fire?
What is radiation.
What is a producer? Give an example.
What is something that makes its own food.
Name the fronts and the weather it brings.
What is
A cold front happens when cold air pushes in and replaces warm air.
It usually brings quick weather changes like rain, thunderstorms, or cooler temperatures.
A warm front happens when warm air moves in and slides over cold air.
It usually brings light rain or drizzle, followed by warmer, nicer weather.
You push a ball and it starts rolling, but the grass causes it to slow down. What is this called?
What is friction.
Sara added 15 grams of ice to a cup. After the cup melts, how many grams are in the cup?
What is 15 grams.
What type of heat transfer comes from touch? Give an example.
What is conduction.
What type of organism breaks down dead things?
What is a decomposer.
Difference between Jet Stream and Gulf Stream.
What is
Jet Stream- a narrow, fast-moving air current that flows high above the Earth’s surface in the upper atmosphere.
It is driven by differences in temperature between the equator and the poles, and by the rotation of the Earth.
Gulf Stream- a powerful and warm ocean current that originates in the Gulf of Mexico and flows along the eastern coast of the United States before crossing the Atlantic Ocean towards Europe.
What happens when forces on an object are unbalanced?
What is the object will move or change direction
Melting ice is what type of change?
What type of heat transfer comes from hot air rising and cold air sinking? Give an example.
What is convection.
What would happen if all plants died in an ecosystem?
What is the food chain would be disrupted.
Name the air pressures and the weather they bring.
High Pressure- Happy weather.
Low Pressure- Lousy weather.
Which surface causes the most friction: tile, carpet, or ice?
What is carpet.
What is force?
What is push or pull
Which is most responsible for the uneven heating of the air in the atmosphere?
What is convection.
What is the role of a consumer in a food chain?
What is to eat other organisms.
Which cloud type brings severe thunderstorms?
What is cumulonimbus
Two students push on a box from opposite sides with equal force. What happens?
What is the box does not move (balanced force).
What evidence shows a chemical change is happening?
What is color change, gas bubbles, temperature change, new substance being formed.
A pot is heated on a stove. Which process causes the metal handle of the pot to also become hot?
What is conduction.
How does energy flow in a food chain?
What is from producers to consumers to decomposers
What is barometer (air pressure), anemometer (wind speed), Thermometer (temperature), Wind vane or a wind sock (wind direction), hydrometer (huidity)
