Hydrogen, helium, sodium, carbon, nitrogen, oxygen lithium, iron, nickel, copper, gold, lead, zinc
Do solids hold there shape?
Yes
Name the one thing that can be found in all 3 states of matter: solid liquid and gas.

Can you use your senses to describe matter?
Yes! How something looks, feels, sounds, smells, or tastes, are all properties of matter.
Can you measure mass on a scale?
Yes
What is volume?

Hydrogen and oxygen (H2O = Water)
Do solids and liquids have a definite volume?

What happens when a liquid turns into solid?
It freezes
How is the periodic table organized?
The elements are organized by their atomic number, beginning with #1. The elements are also organized into 3 different groups: metals, non metals, and semimetals.
What is the difference between a physical and a chemical change?
When a physical change occurs, the matter looks different but is still the same matter. when a chemical change occurs, a new kind of matter forms and has different properties.
How are freezing and melting alike? How are they different?
Freezing and melting are both changes of state between liquid and sold.
Freezing occurs when a liquid loses energy. (Cold temperatures remove energy)
Melting occurs when a solid gains energy. (Heat adds energy)
