Radiation Design - Scoring Rubric

#1 (pg. 2)	1.1 Purpose (States any purpose) The student restates in his or her own words either (1) the purpose of the experiment (for example, "to find the paint that would keep a building coolest") or (2) what the experiment is trying to determine (for example, "which paint will keep the water the coolest" or "what are the rates of heat gain"). Note: Almost always give credit unless only a conclusion is specified.
#2 (pg. 2)	2.1 Volume lists "volume of water" or "amounts of water" or measurement such as "20 ml" (ml alone also okay) 2.2 Distance from test tubes to lamp measurement such as "10 cm" or "6 in away" okay units alone (cm or in) also okay, "same place" not okay 2.3 Times at which measurements are taken (time, interval measurement such as "30 sec," or units such as "seconds" also okay) 2.4 Other (Variables must be possible confounding factors - for example, "initial temperature" or "temperature," "depth pf thermometer" or "wattage of light bulb." Items copied directly from the materials list are not acceptable.
#3 (pg. 3-4)	(For scoring this question, information clearly conveyed in figures, tables, diagrams, etc., in answer to question 3 should be credited.) 3.1 Materials - lists or illustrates 2 or more (any list okay) 3.2 Steps - 2 or more are numbered. Lists any series of at least two numbered steps for procedure ("first, second, etc.," "a, b, etc." okay)
#3 (pg. 3-4)	3.3 Rate - takes temperature at specified time intervals or records time for temperature to increase to a certain value for at least one tube. procedure measures temperature as a function of time (e.g. "measure temperature , after 5 minutes measure again," "take temperature every 30 seconds") or measures time as a function of temperature (e.g. "write down how long it takes for temperature to increase 10 degrees") must clearly imply use of a thermometer with statements such as "take temperature," "check thermometer," "put thermometer in tube - check" ("see how much it heated up" is also okay) temperature checked only at the end of a time interval is acceptable only if three tubes are heated and measured simultaneously 3.4 Tubes - tests 2 or more different colored Procedure performed for different colored test tubes, either sequentially or simultaneously (general reference okay, for example, "change the test tube color" or "do the same with the other test tubes"). Just mentioning three tubes but measuring none is not okay. Note on variable measurement and control: The student may choose to add replication trials or trials in which confounding factors are treated as variables (e.g., "use 10 ml of water for the first trial, 20 ml for the second") Give credit where appropriate for specifying amounts, but do not give credit for using same procedure unless the important variables are also controlled in other trials.) 3.5 Volume - specifies or controls amount of liquid in tube Procedure must explicitly measure volume or assert that the same amount of water must be used for each test tube; responses such as "fill the test tubes" are not acceptable. 3.6 Distance from lamp specified or controlled distance measurement given (e.g. 10 cm) or student asserts that the distance must be the same for each tube or all colors are tested at the same time with one lamp 3.7 Uses the same procedure for all tubes Same measurements specified for each tube or measurements are made for the first tube and instructions are to "do the same with the other test tubes" simultaneous testing is okay
#4 (pg. 5)	4.1 All 3 tubes (colors) labeled on table 4.2 Time (intervals or to criterion) at least 2 headings with "sec" or "min" or criterion heading (e.g. "temperature after 5 minutes") (unit of time is needed: "start" and "end" not okay) 4.3 Temperature in chart title or heading (can be indicated by title or heading with the words "temperature," "degrees" or "deg. C")
#5 (pg. 5)	5.1 Temperature in first blank (degrees Celsius) ("temperature," "heat" or "5 degrees" not okay) 5.2 Time in second blank (minutes, seconds, or time interval such as "30 seconds")

Graph - Results 1.9 Proper slope (all plots indicate heating) 1.10 0 sec= 25 degrees Celsius for all three trials.

#2 (pg. 3)	2a Trials 2a.1 Pattern (1,2,3,2,2) Numbers must be used Entire pattern must be described Rate must be indicated ("degrees Celsius/min." is best; "degrees for each time interval" is acceptable) Rates of cooling for minutes 1-5 of trial 1, in degrees Celsius/min. are 1,2,3,2,2 Must refer to time (& temp). If mentioned first time, then can infer in next two, but some interval must be indicated. 2a.2 Summary- mean rate, total change or comparison of rate, speed or amount of temperature change makes an accurate (but can be approximate) statement about one of these features of trial 1: average change (e.g. "it decreased 2 degrees per minute") total change (e.g. "it changed 10 degrees," endpoints alone are not sufficient) comparison to another trial in speed amount or rate (e.g. "the temperature decreased more slowly than trial 2." Note: if comparison is made to a specific other trial, give summary credit for both trials) 2b (pg. 3) 2b.1 Pattern (2,3,2,4,4) Numbers must be used Temperature list alone not sufficient Entire pattern must be described Rate must be indicated ("degrees Celsius/min" is best; "degrees for each time interval" is acceptable) Rates of radiation for minutes 1-5 of trial 2, in degrees Celsius/min are 2,3,2,4,4 2b.2 Summary - mean rate, total change or comparison of rate, speed or amount of temperature change.
