3.3.3 Lab: Investigate Resource ConsumptionDry LabThe Living Earth Sem 2Points Possible:50Name:Joseph HarutunyanIn this lab, you will be modeling resource consumption using cereal and spoons. You willthen design your own simulation and make some inferences about resourceconsumption in the real world. As you go through the lab, imagine that the cereal youare using is a real resource such as water, food, energy, land, minerals, coal, lumber, orwildlife.Be sure to:Follow safe practices during this investigation.Think about what you are modeling as you go through the investigation. Thepieces of cereal represent a real-life resource. Keep in mind that the cereal couldbe water, food, minerals, land, or other resources.Materials
NOTE: You do not need these materials in order to complete the dry lab.100 pieces of cerealTable2 spoons of the same sizeCupTimer or clock that shows secondsOther small items (e.g., paper clips, beans, pasta, rice, etc.)Other grasping devices (e.g., tweezers, tongs, fingers, etc.)PencilPaperProcedurePart 1: Modeling Resource ConsumptionA student set up and performed the three tests described below. These tests were partof an experiment designed to test the independent variable of placement of naturalresources and its effect on the rate that resources can be obtained.
1.Test A. Even Distribution of Nearby ResourcesSpread 100 pieces of cerealrelatively evenly across the surface of the table. Be sure you are able to reach allof the pieces easily.2.Place the cup in front of you, and set the timer for 1 minute.3.Hold a spoon in each hand, as you would if you were using them to get a servingof salad.4.Start the timer, and begin collecting pieces of cereal one at a time using bothspoons. Place each piece collected in the cup before trying to collect another. Donot move the cup.5.After 1 minute, count the pieces of cereal in the cup. Record the number underTrial 1 in the correct row of the table in the Data for Part 1 section.6.Repeat steps 1 through 5 two more times. Record the results in the propercolumns for trials 2 and 3.1.Test B. Uneven Distribution of Nearby ResourcesSpread 100 pieces of cerealunevenly (in small patches separated by some space) on the surface of the table.
