Organisms and Ecosystems
A community of living things and their environment working together.
Ecosystem
This property describes how much space an object takes up.
Volume
What is the invisible force that pulls objects toward each other and keeps us grounded on Earth?
Gravity
A natural body that revolves in an orbit around a star
A planet
This state of matter has a fixed volume and shape
Solid
These are the living parts of an ecosystem
Biotic Factors
This property tells whether an object sinks or floats in water.
What is density?
Which force acts against motion and slows objects down when two surfaces rub against each other?
Friction
is long term weather patterns
Climate
This state of matter adapts to fill the shape of the container.
Liquid
Sunlight, water, and air are examples of these
Abiotic factors
Color, texture, and shape are examples of these.
Physical properties
What scientific unit do we use to measure the amount of force applied to an object?
Newton
An organism that can survive in both in land and water
Amphibian
This has no definite shape or volume and molecules are free flowing
Gas
Organisms that make their own food using sunlight.
Producers
A student uses a balance to find this property of a rock.
Mass
When forces are equal in size and opposite in direction, they cancel each other out. What do we call these?
Balanced Forces
The layer of gasses that surround places
Atmosphere
A student desk would be an example of this state of matter
Solid
Mushrooms belong to this group that breaks down dead matter.
Decomposers
A substance that dissolves another substance to form a solution
Solvent
What type of forces cause an object to change its speed or direction of motion?
Unbalanced Force
