100
This is the smallest "whole" particle of matter in the universe
An atom!
100
The movement of these particles in an atom is what powers the device you are zooming on right now.
Electrons

What are acceptable Units for the Density of your laptop?
g/cm3 or grams/cm3 or kilograms/cm3
100
What does SULTAN stand for??
Scale, Units, Labels, Title, Accuracy, Neatness
100
What are the 4 basic states of matter in order from least molecular motion to most molecular motion?
Solid, liquid, gas, plasma
200
This is an uncharged particle in the nucleus of the atom.
What is a neutron
200
True or False: Electrons are attracted to each other and will get as close as possible to other electrons
False!
200
This is the number of protons in the nucleus of each atom of an element
What is the atomic number
200
What are the 6 basic steps of the Scientific Method?
Question, Background Research, Hypothesis, Experiment, Conclusion, Share Conclusions

What happens to atoms/molecules in order to change from a gas into a plasma?
Atoms and molecules in a plasma are moving faster than atoms and molecules in a gas, but the big difference you need to mention is that electrons get knocked out of orbitals/shells so that IONS are created! This gives off light and heat.
300
This is a positively charged particle in the nucleus of the atom
What is a proton
300
Metals are good _________ of heat and electricity.
Bonus: WHY? hint...
Conductors
Metals conduct heat and electricity well because the electrons of metalic elements move freely from atom to atom in a "sea" of electrons!
300
This is the sum of an atom's protons and neutrons
Atomic Mass
Helium's Atomic Mass = 4-ish

We will eventually make and measure the height of fire tornadoes after using different amounts of lighter fluid. In this experiment, what is the independent variable and what is the dependent variable?
IV: Amount of lighter fluid
DV: Height of the fire tornado
300
If I have a closed container of molecules and I push down the lid to make the volume smaller, what happens to the pressure inside that container?
The pressure increases (molecules have less space to move, so hit the sides and themselves more often).
400
Most models we have to draw of atoms are misleading because...
(2 reasons)
1. The electrons in the drawings are too big! In reality, electrons are 1/1800 the size of protons
2. The electrons in the drawings are too close to the nucleus. In reality, 99% of an atom is empty space!

1. Vocab term for poor conductors of heat and electricity.
2. Each team member find an example and show in their video square!
1. Insulator
2. Plastic, rubber, paper

Calculate the density of Meg's laptop using the following information...
Mass = 1290 g
Volume = 30 cm wide × 21.2 cm length × 1.6 cm high
Hint: remember UNITS!!!!
Density = Mass/Volume = 1290 g / 1017.6 cm3 =....
1.27 g/cm3
(Volume = 1017.6 cm3)
400
We will eventually make and measure the height of fire tornadoes after using different volumes of lighter fluid. After gathering data, what type of graph would we make and WHY?!
Scatter plot/line graph because both of the variables will yield numerical values (aka: numbers n' numbers my friends!)
400
Let's say we take a popcorn kernel and place it on a metal pan that has a plasma flame under it. What happens to the solid and liquid molecules inside the popcorn kernel?
The molecules inside the kernel move faster due to conduction of heat energy, then they change into the gas state of matter, at which point the kernel cannot withstand the pressure and the molecules explode outward!
500
This is a single atom of what element....
Bonus: How do you know??
Lithium! Because there are 3 protons (red because there are the same number of electrons)
500
Explain why this circuit is on fire!
There is nothing to provide resistance to the flow of electrons, and thus they produce excessive heat energy. These wires would feel extremely hot to the touch!
500
Define the scientific term: Temperature
BONUS: What has faster moving molecules --> A hot, solid metal pan in the oven or a cool glass of liquid water from the fridge?
The measurement of the AVERAGE energy of atoms or molecules in a material or substance.
The solid hot pan!

We will eventually make and measure the height of fire tornadoes (cm) after using different amounts of lighter fluid (mL). In this experiment 3 years ago, a group of students made a graph with the following equation for the slope of the line: y = 1/2x
What are the units for the slope?
The slope means that the tornado increases ___ cm for every ____ mL of lighter fluid we add to the fire.
y = 1/2x
What are the units for the slope? cm/mL
The slope means that the tornado increases __1_ cm for every __2__ mL of lighter fluid we add to the fire.
