Matter & Atoms
The smallest unit of an element.
What is an atom?
The force that pulls objects toward Earth.
What is gravity?
These should always be worn to protect your eyes during experiments.
What are safety goggles?
The first step in the scientific method.
What is asking a question (or making an observation)?
The planet we live on.
What is earth?
This state of matter has a definite shape and volume.
What is a solid?
Energy stored in food and fuel.
what is chemical energy?
If you accidentally spill chemicals on your skin or clothes, you should do this immediately.
What is tell the teacher (and rinse with water if told to)?
An educated guess in an experiment.
What is a hypothesis?
The state of matter that fills the shape of its container.
What is a liquid?

What is kinetic energy ?

Why long hair should be tied back during lab experiments.
What is to keep it from catching fire, spilling into chemicals, or blocking vision?
The step where you explain if your hypothesis was correct.
What is the conclusion?
