unit one:
- control vs. variable? dependent vs. independent variable?
- x vs. y : making a graph
- precision vs. accuracy: accuracy: actual truth, precision: how detailed
- mks system: kg, km, m3
- prefixes kilo, mega, giga, centi, milli, micro, nano
- unit conversion: km to millimeters
- temp: K, C, F
Next steps: dimensional analysis
- If Kona is 45 miles away, how many inches is this? (I promise, we will not use inches anymore!)
- Convert this into km, then into mm (scientific notation anyone?)
- Your computer holds 250 gB of data. How many mB, and kB is this? (cool story here about bytes and bits)
- Look up your body temp in °C then the temp today where you live or grew up. Convert to °F
- You know your weight within a few pounds, calculate this in grams
Next:
Matter, atoms, p, n, e, nucleus
chemical reactions, phase changes, 4 states of matter (4?)
fp, mp, bp, vaporization, ionization, condensation, sublimation (ax murderer becomes butcher)
periodic table, atomic number, atomic mass (why so weird?)
families/groups (columns), periods (rows)
isotopes, ions
energy levels

LInk to unit 2:
----------------------------------------------------
compounds vs. mixtures
chem formulas, rule of 8
solvent, solute
solubility: solids into liquids (warm them up), gases into liquids (cool them down)
pressure and solubility: bends, perrier water, no ice in your fast food drinks!
concentration: usually liquids or gases, rarely solids or plasmas
