Review day!

Physical Science, May 16th and 19th

2008-05-20T15:50:33Z

Physical science:

Collect KM HW #1
Stamp KM HW #2
Questions on HW #2?
Questions on 2.1-2.9?
- answer both of these on overhead
Demo: 2.10: set up tracks and ramps: one at relatively constant motion, one at speeding up, right next to each other. Start two marbles at the same X, such that the constant motion starts out faster, then they have the same speed, then the speeding up marble passes the other.
- Direct students to 2.10: they should diagram the path, ramps, and answer the question.
- As a class, have them call out "SAME!" when the two marbles have the same speed.
- Break it down ito the two groups: one group will call out when they have the same instantaneous velocity, one group when they pass (same average velocity). Discuss both.
Pass out review sheet: students should work problems on notebook paper.
Remind: data (qual and quant) and graph due next time, KM quest next time, packet and HW #2 will be due!

Chemistry:

Review: HW problems
Tiny little lecture: percent composition (make up example problems)

working to get percentages - what is the % by mass of each element in H2SO4? in C8H17?
working from percentages - if a substance is made of 36.84% N and 63.16% O, what mass would you have of each in a 100g sample? in a 37.56g sample?

Review: calculations on Molympics

take notes in comp book
add percent composition problems as we go

Water; measure 1 mol by mass, measure volume of that mol.

add: what is percent comp of water?

Aluminum: measure mass, calculate moles, use $0.081/mol to find cost
Silicon: measure mass, calculate moles, calculate # of atoms
Carbon: measure 1 mol by mass, use 0.2g/carat to calculate carats (compare volume in imagination)
NaCl: salt "fries," measure mass, calculate moles, (divide by # of shakes to get 1 shake.)

add: what is percent comp of NaCl?

Tungsten: measure mass, calculate moles, calculate # of atoms
Sucrose: measure mass of gum, chew gum, measure mass of chewed gum. Difference in mass is mass of sucrose dissolved. Calculate moles of sucrose, then use 1282.5 Cal/mol to find Calories
Calcium carbonate: measure mass of chalk, write with chalk, then measure mass of chalk again. Difference in mass is mass of chalk used. Calculate moles of CaCO3

add: calculate percent comp of CaCO3, then use it to find what is the actual mass of Ca in this sample?

Sulfur: measure mass of sulfur sample, calculate moles, calculate # of atoms. Use 3.75 x 10^21S atoms/match to find how many matches this sample could make.
Baking soda (sodium bicarbonate): measure the mass of the soda sample, calculate moles, calculate formula units. Write equation and balance: NaHCO3 + 2HCl --> NaHCl2 + H2O + CO2. Use ratio: 1 f.u. NaHCO3 reacts with 2 f.u. of HCl, so # of f.u. calculated of NaHCO3 requires twice as many f.u. of HCl.

HW: Turn in Molympics next time; practice; remember that test is coming up! (May 5th and 6th)
