Nature of Science
This is a testable explanation for an observation that can be investigated.
What is a hypothesis?
This sphere includes rocks, soil, and landforms.
What is the geosphere?
This is Earth’s thin, solid outer layer, where we live.
What is the crust?
This process changes liquid water into water vapor
What is evaporation?
This is the basic unit of life.
What is a cell?
In an experiment, this is the one factor a scientist deliberately changes.
What is the independent variable?
This sphere includes Earth’s oceans, lakes, rivers, and groundwater.
What is the hydrosphere?
This thick layer of hot rock lies beneath the crust.
What is the mantle?
Water vapor cools and changes into tiny liquid droplets, forming clouds. This process is…
What is condensation?
This force pulls objects toward Earth.
What is gravity?
A scientist repeats an investigation several times. This helps make the results more…
What is credible
What does the geosphere provide for the plants of the biosphere?
What is soil?
This innermost layer is solid and made mostly of iron and nickel
What is the inner core?
Rain, snow, sleet, or hail falling from clouds is called…
What is precipitation?
In a food chain, organisms that make their own food using sunlight are called…
What are producers or autotrophs?
A class tests whether different amounts of sunlight affect plant growth. The plants receive the same kind of soil and amount of water. These kept-the-same factors are called…
What are controlled variables?
A plant absorbs water from soil and releases water vapor into the air. Name the three spheres interacting.
What are the biosphere, geosphere, and atmosphere?
Unlike the solid inner core, this layer of iron and nickel is liquid
What is the outer core?
Water that flows over the land into streams, rivers, or lakes is called…
What is runoff?
A material that allows heat or electricity to pass through it easily is called…
What is a conductor?
student’s results do not support the original hypothesis. The best next step is to…
What is repeat the experiment and record results
Rain washes soil from a hillside into a river, where it may affect fish. Name the four spheres involved.
What are the atmosphere, geosphere, hydrosphere, and biosphere?
Put Earth’s four main layers in order, starting at the surface and moving toward the center.
What are the crust, mantle, outer core, and inner core?
Water vapor released from plant leaves into the atmosphere through the water cycle is produced by…
What is transpiration?
In a fair test, a student changes the type of surface under a toy car and measures how far it travels. The measured distance is the…
What is the dependent variable?
