1213+Measurement+Project

How heavy is the artificial turf on the new fields?
Goal: You and your partners will measure the dimensions of one of the new fields, including uncertainty in the measurement. You will also measure the mass of some of the turf. Using these measurements, you will determine the maximum and minimum mass of turf that covers the surface of the playing area you measured.

Tools: Trundle wheel - it has a wheel that is one meter in circumference. Triple Beam balance A sample of turf material.

Roles: Recorder, equipment manager, counter

Plan: Measuring the field:
 * 1) Each group will be assigned one of the new green areas: the soccer field or the elementary play area.
 * 2) Each group will plan and prepare a data table to hold the measurements. This table must be written neatly in the recorder's science notebook.
 * 3) The equipment manager will obtain one trundle wheel.
 * 4) The group will go outside. As the equipment manager pushes the trundle wheel, the counter will count how many times the wheel turns.
 * 5) The recorder writes down the measurement. The group should decide on the level of uncertainty in each measurement.
 * 6) Each measurement should be repeated. If the second measurement does not agree with the first, a third attempt is required

Measuring the turf material.
 * 1) The goup will plan and prepare a data table to hold the measurements. This table must be written neatly in the recorder's science notebook.
 * 2) Each group can cut one piece of turf and determine its mass and area.
 * 3) The equipment manager will make sure the triple-beam balance is used correctly.
 * 4) Use the balance to determine the mass of the piece of turf. Calculate the mass of one square meter of turf.

Calculations
 * 1) Determine the area of the field or play area in square meters. Think about the uncertainty in your measurement and use it to calculate the maximum and minimum size of the field.
 * 2) Multiply these numbers by the mass of turf per square meter. Remember to do the calculation twice, using both the largest mass of turf per meter and smallest mass of turf per meter.
