Matter & Energy
The measurement of how much matter is in an object, typically measured in grams.
Mass
This is a push or a pull that can change the position or motion of an object.
Force
These are "giant frozen dirty snowballs" that orbit the sun; or more commonly, the process of breaking down rocks into smaller pieces.
Weathering
In a food web, these organisms get their energy by breaking down dead plants and animals.
Decomposers
You should always wear these to protect your eyes during an experiment.
Safety goggles
If an object is more dense than water, it will do this when placed in a graduated cylinder.
Sink
Light energy traveling in a straight line that bounces off a shiny surface (like a mirror) is called this.
Reflection
A U-shaped valley is most likely formed by the slow movement of this.
Glacier
This is a behavior an animal is born with, rather than one it has to be taught.
Instinct or inherited behavior
This tool is used to measure the volume of a liquid accurately.
Graduated Cylinder
This type of mixture involves one substance dissolving evenly into another, like salt in water.
Solution
A circuit must be this (unbroken) for electricity to flow and light a bulb.
Closed Circuit
This is the process of sediments being dropped off in a new location, often forming deltas.
Deposition
Carbon dioxide enters a plant and Oxygen leaves a plant through this process.
Photosynthesis
This tool uses two lenses to make very small objects appear much larger.
Microscope
This is the temperature at which water changes from a liquid to a gas (water vapor).
100 degrees Celsius
When light passes from one medium to another (like air to water) and appears to bend, it is called this.
Refraction
Earth experiences day and night because it does this on its axis every 24 hours.
Rotation
A bird’s beak shape or a cactus’s waxy coating are examples of this—a trait that helps an organism survive.
Adaptation
To compare the weights of two different objects, a scientist would use this tool.
Triple Beam Balance
These materials, like copper and aluminum, allow thermal or electrical energy to flow through them easily.
Conductors
This force acts between two surfaces sliding against each other and creates heat.
Friction
These types of fuels (coal, oil, natural gas) were formed from the remains of ancient plants and animals over millions of years.
Fossil Fuels
In an energy pyramid, this group of organisms is always found at the very bottom.
Producers
This is a predicted answer to a scientific question that can be tested.
