  1. Steel Wool Lab • Mass the aluminum foil and record (1). • Unroll the steel wool, pulling the strands as far apart as possible to get maximum surface exposure. • Mass the unburned steel wool (with aluminum foil to protect scale) and record (2). • Hold the burning steel wool and match over the aluminum foil (to catch all product). • Hold the steel wool over the flame using tongs. Be careful; it will burn rapidly and some steel wool may break off from the bulk. • Move the tongs and burn any unburned portions of the steel wool WITHOUT stretching/pulling. • When the reaction is over, find the mass of the burned steel wool with the foil and record (3). • Subtract the mass of the foil from the mass of the unburned and burned steel wool and foil and record (4). • Subtract the mass of the unburned steel wool from the burned steel wool and record (5). • Have one member of your group record the lab group’s data on the board for the mass of unburned steel wool and the mass of the burned steel wool. • Stamp for spotless lab station • Clean your lab station (spotless!) Cool the used steel wool and dispose in trash. Shake out and save the aluminum foil for the next class.Record all groups’ data and add up the totals.
