Weather/Water Cycle
What is the process called when water vapor turns into liquid water?
Condensation
What is the force that pulls objects toward the Earth?
Gravity
What is matter?
The amount of mass an object has.
What is the term for living factors in an ecosystem?
Biotic
What is the building blocks of life called?
Cells
What is the measurement that tells us how much water vapor is in the air?
Humidity
Name one factor that can affect how fast an object moves.
Factors include mass, friction, and applied force
What are the three states of matter?
Solid, Liquid, and Gas
Name one type of ecosystem and a feature that makes it unique.
Example: A rainforest, known for its biodiversity.
What are traits that are passed from parents to offspring called?
Inherited Traits
What is a cold front and how does it affect weather?
A cold front is the leading edge of a cooler air mass that pushes under a warmer air mass, often bringing thunderstorms and a drop in temperature.
How does increasing mass affect the acceleration of an object when the same force is applied?
Increasing mass decreases the acceleration
What is the difference in mass and weight?
Mass is how much matter is in an object, and it does not change depending on location. Weight is the pull of gravity on an object and can change depending on location (Earth vs. Moon).
How do producers, consumers, and decomposers interact in an ecosystem?
Producers create energy, consumers eat producers or other consumers, and decomposers break down waste.
What is the difference between instincts and learned behaviors?
Instincts are behaviors animals are born with; learned behaviors are acquired through experience.
What type of weather is typically associated with a stationary front?
Stationary fronts can lead to prolonged periods of cloudy skies and steady rain or light precipitation.
What is Newton's First Law of Motion?
An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.
How does temperature affect the state of matter?
Heating can change solid to liquid (melting) or liquid to gas (evaporation).
What do the arrows represent in a food web?
The flow of energy
What are the 6 body systems we learned about?
Skeletal, Muscular, Digestive, Respiratory, Circulatory, and Nervous Systems.
Precipitation, Collection, Transpiration, Run-off, Evaporation, and Condensation
If a toy car travels 15 meters in 3 seconds, what is its average speed?
The average speed is 5 m/s (calculated as Speed = Distance รท Time.)
When two substances mix and create a new substance, what is this called?
A chemical change/reaction
What can happen if one species is removed from an ecosystem?
It can disrupt the food chain and lead to population decline or extinction of other species.
Compare the functions of the muscular and skeletal systems.
The muscular system enables movement, while the skeletal system provides structure.
