2 REQUIRED TITLE SLIDE THE AFFECT THE DEPTH OF SAND HAS ON CONVECTION CURRENTS By Diana Kelly Title is the broad area of studyFirst and Last Name are after the titleMay decorate with small, discreet, clip art or other media that is relevant to the topic in the corners to not block the title or name
3 PROBLEM: Hot sand burns bare feet PROBLEM: Hot sand burns bare feet. PURPOSE: To determine if digging a path to moist sand would reduce the sand temperature and prevent feet from blistering which is 18% of the body sections.PROBLEMPURPOSE1 source Conductionhighlighted dataTime to go to the beach! The surface of the sand is really hot at the beach. Just a few inches down the sand is really cold. Objects transfer heat at different rates. Scientists call that ability thermal conductivity. Sand has a very low conductivity. At the beach, the sand acts like a big insulator. The sand on the top gets very hot, but conducts very little heat to the ground below1 sourcehighlighted data REFER TO VOCABULARY2 source Jul 26, 2010 posted by: Joe Ciccantihighlighted data Millville Medical Center because of burns to the bottom of her feet. She had to be treated for—large blisters—skin blistering.2 sourcehttp://firstaid.about.com/od/softtissueinjuries/a/07_burn_surface.htmhighlighted dataThe Rule of NinesTo approximate the percentage of burned surface area, the body has been divided Right leg (below the knee) Left leg (below the knee)Each of these sections takes about nine percent3 source CHOP Diabetes Center for children, Summer Foot Care Tipshighlighted data If your child gets a cut, insect bite or blister, give proper care and make sure it heals quickly Avoid walking barefoot3 source
4 REQUIRED QUESTION SLIDE Will a digging a path in the sand reduce the temperature of the walkway path to prevent feet from blistering when walking on hot sand on 95 degree days?1 Question answers the problem via an experiment2 Question relates to the problem and purpose3 One question is asked
5 REQUIRED QUESTION RESEARCH SLIDE Will digging a path in the sand reduce the temperature of the walkway path to prevent feet from blistering when walking on hot sand on 95 degree days?1 source Conductionhighlighted dataTime to go to the beach! The surface of the sand is really hot at the beach. Just a few inches down the sand is really cold. Objects transfer heat at different rates. Scientists call that ability thermal conductivity. Sand has a very low conductivity. At the beach, the sand acts like a big insulator. The sand on the top gets very hot, but conducts very little heat to the ground below2 sourcehighlighted data You may also check text books on "heat transfer in porous (or multiphase) media.”3 sourcehighlighted data plastic tube, about 20 mm in ID and about 200 mm in length. Fill the tube with the mixture and block the two ends tight with two thin (5-10 mm) cooper disks. Insert a few thermocouples at 20 mm internals (from end to end) into the tube. Steadily heat one of the copper disks at one end and cool the other copper piece at the other end. Moderate heating is sufficient.
6 REQUIRED HYPOTHESIS SLIDE If sand temperatures are measured at vertical depths of 0 cm (control), 2 cm, 4 cm, and 6 cm; then the 6 cm vertical depth will be the coldest temperature.Formatted as an if…then statementPosition is stated as an outcome measurement (dependent variable)Independent variable included and data provided for experimental groupsSupports research
7 REQUIRED VOCABULARY SLIDE Thermal conductivity is the quantity of heat transmitted through a unit thickness in a direction normal to a surface of unit area, due to a unit temperature gradient under steady state conditionsThermal conductivity measured in k - at oC 25Sand, dry LOWER NUMBER MEANS LESS HEAT IS GOES DOWN THROUGHSand, moist THE SAND SO THE SURFACE IS HOTTERSand, saturated 2 - 4
8 REQUIRED MATERIALS SLIDE NOT a numbered listAll needed materials to complete the experiment are includedAmount needed and measurement of material are clearly discernible EXAMPLES:500 ml glass beakerTwelve 250 ml paper cups6 glass stir rods(12)250 ml paper cups(6) glass stir rods
9 REQUIRED PROCEDURE SLIDE(s) each slide is titled procedure No pronounsVerb (action word) starts blurbNumbered stepsBlurbs in order needed to perform experimentMeasurements and quantity used or times performed includedRepeated steps refer to number and state “Repeat steps x through y” for experimental group z or control groupFill the plastic lid measuring l w h with 8 cm of sand.Tap the lid on a flat surfaceuse a ruler to measure the depth at the four corners and approximate centerRepeat steps 1-3 to achieve an even vertical depth of 8 cm throughout the lidMark the edges of the plastic lid by placing painter’s tape on the flat surface to maintain the same positionPosition a sun lamp 10 cm above the plastic lidTo measure sand temperatures use a thermometer with masking taped markings measured at 0cm, 2 cm, 4 cm, and 6 cmPush the thermometer down to the 6 cm marking in the center of the lidWait 30 seconds,Recording the temperatureWithdraw the thermometer to 4cm and repeat steps 8-11 in the 4 corners at 4 cm, 2 cm, and then 0 cmTurn on the sun lamp, check surface temperature every 30 min until surface temperature is 80 C or greaterRepeat steps 8 through 12
10 REQUIRED PHOTOGRAPH SLIDE Photographs of procedure being performed
11 REQUIRED DATA SLIDE DATA IS NOT THE TITLE Title defines data actually collected (the independent variable, dependent variable, AND control are stated) EXAMPLE: Temperature of sand at 0 cm , 2 cm, 4 cm, and 6 cm below the surface.Data is in a tableData includes averagesData is in metric unitsData is a measured outcome of the independent variable (related)
12 REQUIRED GRAPH SLIDE(S) Title of slide is X axis title vs Y axis titleOne graph may show all data and averages or more than one graph may be neededIf time is used as a variable the data for the sample is kept together on different graphs to avoid confusion and an average graph has all data of all samples8 parts to a graphtitle of graph is x axis title vs y axis titlex axis title (independent variable)y axis title (dependent variable)x axis label in lower right cornery axis label in upper left cornerscale of x is accurate, metric, and spans the graphscale of the y is accurate, metric, and spans the graphdata is clearly plotted (key if needed)
13 REQUIRED ANALYSIS SLIDE Bullets for blurbs that discuss graphed resultsAnalysis includes specific sample name and measured independent variableAnalysis is sufficient to provide details to the conclusionNo opinions are statedNo reason for outcome is providedConsists of only an analysis of the data as presented in the graphs
14 REQUIRED CONCLUSION SLIDE Reflects a restatement of the hypothesisIncludes the result that related to the problem, purpose, and questionDoes not provide opinionDoes not provide reasonDoes not state I was right or wrong, my hypothesis was right or wrong, accepted or rejectedReflects only the restatement of the hypothesis to reflect the results collected in the data.
15 REQUIRED WEAKNESSES/IMPROVEMENTS SLIDE Thoughtful consideration given to…Lab practices/techniquesControl of experimentAvailable equipmentNeatness to prevent cross contamination
