Quiz on vocabulary

Review video on Periodic Table

Review demo of lighting magnesium - required shavings - could not light the solid bar
Important result - crumbling (increasing surface area) increases the rate of reaction.

Alka-Seltzer Lab
Lab Title: Factors affecting the rates of reaction
Have students draw data table in notebooks using a ruler

Cold water
Room temp
Hot water
Crumble (hot water)

Measure time for reaction.

Material List

Fill the 10 ml grad cylinder to the brim (quicker than measuring out 10 ml)
Pour into the film canister
Drop in Alka-Seltzer and quickly cap
Time until reaction occurs
Record data

MUST WEAR GOGGLES

Nucleus, protons, neutrons, electrons
Relative masses, size of nucleus vs size of atom
Size of atom - smaller than wavelength of light so can't see it.

Type of element is determined by number of protons in nucleus.

Reaction of 2CH3OH + 3O2 --> 2CO2 + 4H20
Balancing chemical equation
Demo of fire tornado.

Went around room and asked people what they liked about the Physics Extravaganza.
