Scientific Method
The first step of the scientific method.
What is asking a question?
The number of both inner and outer planets.
What is eight?
A scientist who studies fossils.
What is a paleontologist?
The smallest unit of life.
What is a cell?
This body system gives the body structure and protects your organs.
What is the skeletal system?
Your prediction about your experiment (usually an if-then statement).
What is a hypothesis?
The "Goldilocks Zone" around a star is just right for this material to stay liquid.
What is water?
A fossilized bone or other body part from an organism.
What is a body fossil?
These tiny structures do different jobs within the cell.
What are organelles?
Skeletal muscles (like in your arm) always work in this grouping.
What are pairs?
The variable you measure during an experiment.
What is the dependent variable?
The outer planets are made mostly of this.
What is gas?
This era is also called the "Age of Reptiles."
What is the Mesozoic era?
This type of cell is too simple to have a nucleus or other organelles.
What is a prokaryote?

The variable you change during an experiment.
What is the independent variable?
This band of rocky debris divides the inner planets from the outer planets.
What is the Asteroid Belt?

What is the Paleozoic era?
What is dividing?

Aside from Earth, liquid water also exists on this moon of Jupiter.
What is Europa?
The Allosaurus known as "Big Al" died after this broken bone prevented him from hunting.
What was his toe?
This helps give a cell structure, but is only found in plant cells.
What is a cell wall?
This type of muscle is involuntary, striped, and only found in the heart.
What is cardiac muscle?
