5.4.3 Lab: Investigate Resource ConsumptionDry LabEarth/Environmental Science North Carolina (2019)Sem 2Points Possible:40Name:Kelly Hernandez-MartinezDate:03/04/2021In this lab, you will be modeling resource consumption using cereal and spoons. You will then design your ownsimulation and make some inferences about resource consumption in the real world. As you go through the lab,imagine that the cereal you are 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. The pieces of cereal represent areal-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.)PencilPaperProcedurePart 1: Modeling Resource ConsumptionA student set up and performed the three tests described below. These tests were part of an experiment designed totest the independent variable of placement of natural resources and its effect on the rate that resources can beobtained.1.Test A.Even Distribution of Nearby ResourcesSpread 100 pieces of cereal relatively evenly across the surfaceof the table. Be sure you are able to reach all of 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 serving of salad.4.Start the timer, and begin collecting pieces of cereal one at a time using both spoons. Place each piececollected in the cup before trying to collect another. Do not move the cup.5.After 1 minute, count the pieces of cereal in the cup. Record the number under Trial 1 in the correct row of thetable in the Data for Part 1 section.6.Repeat steps 1 through 5 two more times. Record the results in the proper columns for trials 2 and 3.
