Alpha
This is an educated guess or a predictable statement that can be tested.
What is...a hypothesis?
This is the distance from the top of one wave to the top of the next.
What is...wavelength?
This type of circuit has only one path for the electric current to flow.
What is...a series circuit?
Sound is produced by these, which move back and forth very quickly.
What are...vibrations?
When you use your five senses to gather information, you are making one of these.
What is...an observation?
This is the variable in an experiment that the scientist purposely changes.
What is...independent variable?
This type of energy travels in transverse waves and moves in a straight line until it hits an object.
What is...light energy?
Matter in this state has a definite volume but takes the shape of its container.
What is...a liquid?
To ensure an experiment is "fair," these are the factors that must remain the same throughout.
What are...constant/controlled variables?
This is the buildup of electrical charges on the surface of an object, often caused by friction.
What is...static electricity?
What do you call all the living and non-living things that interact in an environment?
What is...an ecosystem?
These four planets are known as the "Gas Giants" because they are large and made mostly of hydrogen and helium
What are...Jupiter, Saturn, Uranus, & Neptune?
This tool is used to measure the mass of an object in grams using the force of gravity.
What is...a spring scale?
Unlike the Gas Giants, the four inner planets (Mercury, Venus, Earth, Mars) are known by this "rocky" name.
What are...terrestrial planets?
This is a substance made of two or more elements that are chemically combined.
What is...a compound?
Rubber and plastic are examples of this - a material that does not allow electricity to flow easily.
What are...insulators?
This is the term for light "bouncing off" a shiny surface like a mirror.
What is...reflection?
This is the instrument used to measure air pressure.
What is...a barometer?
A prism separates white light into the visible spectrum using this process, where light bends as it changes media.
What is...refraction?
This type of cloud is wispy and high-altitude, often indicating a change in weather.
What are...cirrus clouds?
In an experiment testing which fertilizer makes a plant grow tallest, the height of the plant is this type of variable.
What is...the dependent variable?
This type of rock is formed from cooled magma or lava.
What are...igneous rocks?
This is the shallowest part of the ocean floor that surrounds the continents.
What is...the continental shelf?
This is the green pigment in plants that captures sunlight for photosynthesis.
What is...chlorophyll?
As you go deeper into the ocean, two things decrease and one thing increases - what are they?
What is...amount of light & temperature decreases?
AND
What is...pressure increases?
