Energy
What does "KE" stand for?
KE stands for Kinetic Energy
Draw a symbol for a fast moving particle
O )))
What are the three states of matter we learned in class?
Solid, Liquid, gas
What happens to particles in a liquid when you heat it up?
The particles start to speed up and get further apart, change from liquid to gas. (KE and PE increase)
What are the big three?
1. Keep hands, feet, objects to yourself
2. Use appropriate body, including body language
3. Follow directions the first time they are given
Explain what Kinetic energy is.
Kinetic energy is energy due to the motion of particles
Draw a sketch of particles in a low kinetic energy state.
(OOOOOOO)
(OOOOOOO)
Name an example of a gas in the room?
oxygen, nitrogen, carbon dioxide
What do rich clouds do?
They make it rainnnnnnnnnnnnn *money gun*

Who is the principal of Wawona k-8?
Principal Nuno
Explain what Potential energy is.
Potential energy is the energy due to distance between particles.
Draw a sketch of particles with high potential energy
O)) O)) O))
A lot of distance ^
What state of matter holds a constant shape?
solids
How do you throw a party in space?
You Plan-it (planet)
🌎
How many science teachers are at Wawona?
There are 5
(Ms. Poulin, Mrs. Cortez, Mrs. Moreno, Mr. Harris, Mrs. Childs)
What is equation for thermal energy?
TE = KE + PE
Describe particle motion of a liquid
Particles in a liquid flow past each other, Moves faster than a solid but slower than a gas. Can collide with each other.
What state of matter can change its volume?
Gasses
If H20 is the formula for water, What is the formula for ice?
It is H2O but we will take H2O cubed
Who are the two ladies that work in the front office?
Margaret, Monica
What has more energy and why?
-a teaspoon of boiling water
-A bathtub of warm water
A bath tub of warm water has more energy. This is because the bathtub water has more mass and more mass means more particles. When there are more particles there is more energy.
*Remember Bill Nye trying to melt a whole ice sculpture with just one match.
Explain how KE and PE change when heat is added to a substance.
KE and PE increase when heat is added to a substance because the particles speed up and spread out.
What state of matter is compressible?
gasses are compressible
**think of a propane tank
Why can gasses be compressed easily while solids and liquids cannot?
Gasses have large spaces in between particles that allow them to compress together, while solids and liquids have less space.
What are the cross streets of Wawona k-8?
Thorne and Gettysburg
