Unit 1
Anything that has mass and takes up space.
What is matter?
The force that pulls objects toward each other, such as the pull of the Earth on objects, keeping us grounded?
What is gravity?
The processes of the water cycle.
What is evaporation, condensation, precipitation, and runoff?
A warm ocean current that flows from the Gulf of Mexico along the East Coast of the United States, affecting the climate of nearby regions?
What is Gulf Stream?
A community of living organisms (plants, animals, and microbes) and their non-living environment (soil, water, air) interacting as a system.
What is ecosystem?
A combination of two or more substances where each substance retains its own chemical identity.
What is Mixture?
The force that opposes the motion of two surfaces sliding against each other, causing them to slow down or stop?
What is friction?
What is a tool used to collect and measure the amount of rainfall?
What is rain gauge.
Short-term atmospheric conditions in a specific place at a specific time, including temperature, humidity, and precipitation?
What is weather?
Organisms, like plants and algae, that create their own food through photosynthesis?
What is producer?
A type of homogeneous mixture in which one substance (the solute) is dissolved in another substance (the solvent). For example, salt dissolved in water forms a saltwater solution?
What is solution?
The amount of matter in an object, usually measured in grams or kilograms; it determines how heavy something is?
What is mass?
Who is a scientist who studies and predicts weather and climate?
What is a meteorologist.
A cool wind that blows from the ocean to the land during the day due to temperature differences?
What is sea breeze?
Organisms made up of many cells, which can work together to perform different functions.
What is multicellular?
The amount of matter in an object or substance, typically measured in grams or kilograms?
What is mass?
A push or pull on an object that can cause it to move, change direction, or stop?
What is force?
What is an imaginary line that divides the Earth into the Northern and Southern Hemispheres, located at 0 degrees latitude?
What is equator.
A cool wind that blows from the land to the ocean at night, also caused by temperature differences?
What is land breeze.
The basic building blocks of all living organisms, making up tissues and organs.
What is cells?
A fundamental principle stating that certain properties, such as mass or energy, cannot be created or destroyed, only transformed from one form to another?
What is Law of Conservation?
How fast an object is moving, usually measured in units like meters per second or kilometers per hour?
What is speed?
An average weather conditions in a region over a long period, typically 30 years or more?
What is climate?
A powerful tropical storms with strong winds and heavy rain, formed over warm ocean waters?
What is hurricanes?
Muscles that work automatically, without conscious control, such as those in the heart.
What is involuntary muscles?
