In this lab, you will be modeling resource consumption using cereal and spoons. You will thendesign your own simulation and make some inferences about resource consumption in the realworld. As you go through the lab, imagine that the cereal you are using is a real resource such aswater, food, energy, land, minerals, coal, lumber, or wildlife.Be sure to:Follow safe practices during this investigation.Think about what you are modeling as you go through the investigation. The pieces ofcereal represent a real-life resource. Keep in mind that the cereal could be water, food,minerals, land, or other resources.MaterialsNOTE: 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.)PencilPaper
ProcedurePart 1: Modeling Resource ConsumptionA student set up and performed the three tests described below. These tests were part of anexperiment designed to test the independent variable of placement of natural resources and itseffect on the rate that resources can be obtained.1.Test A.Even Distribution of Nearby ResourcesSpread 100 pieces of cereal relativelyevenly across the surface of the table. Be sure you are able to reach all of the pieceseasily.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 serving ofsalad.4.Start the timer, and begin collecting pieces of cereal one at a time using both spoons.Place each piece collected in the cup before trying to collect another. Do not move thecup.5.After 1 minute, count the pieces of cereal in the cup. Record the number under Trial 1 inthe 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 proper columns fortrials 2 and 3.1.Test B.Uneven Distribution of Nearby ResourcesSpread 100 pieces of cereal unevenly(in small patches separated by some space) on the surface of the table. Be sure thecereal covers the same area as it did for Test A.
