| week of | Tuesday | Thursday |
| Jan.18 | Syllabus and Next Generation Science Standards list "treasure hunt" and category sorting quality adjectives (shape & color) c.v. quantities (size & how much) measurement as count of ("×") unit property ... link to metric prefixes link to science journal set-up instructions |
extensive item (object) quantities are additive: L, W, H; Volume=L×W×H; mass
adding water Volumes (=> meniscus) ... adding water masses (=> subtraction as removal) mass as contained material c.v. weight as heaviness pull computing wood's mass density (ratio ρmass = m/V) intensive (material) quantities average: floating or sinking examples intrinsic c.v. incidental (conditional) properties ... workbook pgs 1,3,7,8,9,10,12,13,14,15,16 |
| Jan.25 | item ← materials ← 1 substance or a mixture
% by mass , % by Volume , % by count (examples) : sand + air mixture (salt % ?) : properties (changeable) cv. constituents (conserved) | Quiz 1 ... here's my grading key as pdf
states of matter (phases): solid, liquid, gas, plasma ... properties ... microscopic distinctions ... diffusion thru gas burning candle example & play-doh counter-example phase change vocabulary °C Temperature scale c.v. °F T scale cold water added to hot water ... T's average ⇒ intensive (wkbk 16-20,23-26) |
| Feb.01 | Kinetic Energy (motion) - friction transfers E
Temperature as KE per molecule (average KE) ... some details Energy transfer from hot to cool is "Heating" (E is "conserved") weighted average: small sample has big ΔT - large sample has small ΔT ΔTE = m c ΔT ... c is specific heat capacity ... c table alcohol less effective (low c); iron much less ... (wkbk p.27-30) |
hot liquid melts cold solid ... rotation Energy ΔE = m Lmelt
calibrate a burner: ΔE = Power for a duration boiling water into vapor ... separation Energy Δm Lvaporize pressure-cooker & freeze-drier syringe compression ... then expansion Pressure as Potential Energy density ... P = PE / Volume |
| Feb.08 | Quiz 2 ... here's my grading key as pdf
hi-pressure c.v. hi-Volume pump ... pressure units & P meters atm.P by spring c.v. mercury c.v. water column air-ball P @ room temp ... & in water ice ... & in CO2 ice ... & in boiling water graph P ∝ T data ; find T for P=0 ⇒ Kelvin T scale (∝ E) | sCO2 "dry ice" into CO2 balloon
air into balloon ⇒ V ~ n air-pump mass into bottle ... P ~ n and P ~ ρ buoyant Force: PA = ρm g Volsubmerged He balloon & air balloon into CO2 ice ... V ~ n T |

:
ice storm cancelled class, then electric Power outages : elevated air loses Thermal Energy (as it does Work during expansion) atmosphere depth estimate ~ 7 km Earth surface IR radiation warms troposphere-air 14km ≤ stratosphere ≤ 49km ; ozone warmed by Sun's UV | Volume vs Temperature examples (theory)
gas energy/molecule (at T) depends on molecule shape (related to melting Latent heat/molecule) : Quiz 3 ... here's my grading key pdf (soon) next Tuesday : Unit 1 Exam |
