Decomposition Journal

The students experimented with different material types to see which would rot and which would remain. They calculated decomposition by measuring weights before and after the experiment.

Science Journal: Rot or remain?
	Good 4 pts	Fair 3 pts	Poor 2 pts	Incomplete 0 pts
Variables for fair testing Variables of the experiment to keep it a fair test.	Good Student has documented which variables will be kept the same, observed or changed correctly.	Fair Student has documented two variables that will be kept the same, observed or changed correctly.	Poor Student has documented one variable that will be kept the same, observed or changed correctly.	Incomplete Student has not stated or did not correctly state which variable will be kept the same, observed or changed correctly.
Predictions Predictions of whether a material would rot or not.	Good Students made predictions for all the materials and provided accurate reasons for their predictions.	Fair Students made predictions for most (>3) of the materials and provided reasonable arguments for their predictions.	Poor Students made predictions a few (< 3) of the materials and/or provided poor reasons for their predictions.	Incomplete Students did not make predictions for the materials, nor provide reasons for their predictions.
Measurements Correctly measured the weights of the samples in grams.	Good Both weights of the samples before and after the experiment were documented accurately to 2 decimal points AND in grams.	Fair Most (>80%) of the sample weights before and after the experiment were documented accurately to 2 decimal points AND in grams.	Poor About half of the sample weights before and after the experiment were documented accurately to 2 decimal points AND in grams.	Incomplete A large proportion (> 70%) of sample weights were missing AND/OR not accurately measured in grams.
Documentation Supplied photos/drawings of samples before and after the experiment.	Good Sketches/photos are detailed, and draw attention to the subtle changes in the sample size/quality.	Fair Sketches/photos show some effort to represent observed structural changes.	Poor Sketches/photos show little effort to represent observed structural changes.	Incomplete No sketches/photos were supplied.
Data Tables/Graphs Correctly labelled and title graph showing differences in weight for each sample.	Good Data tables and graphs present. Axes were labelled correctly with correct units on the Y-axis. Data was represented accurately and not misrepresented. A title was supplied. Calculations (W1-W2) were correct and correctly represented.	Fair Data tables and graphs present. At least one axis was labelled correctly with correct units on the Y-axis. Data was represented accurately and not misrepresented. A title was supplied. Calculations (W1-W2) were correct for most of the samples and correctly represented.	Poor Data tables w/o graph or graph w/o data table. Axes were labelled incorrectly with incorrect units on the Y-axis. Data was not represented accurately and misrepresented. Calculations (W1-W2) were incorrect for most of the samples.	Incomplete No data tables or graphs were supplied.
Discussion Discussion of results vs. predictions.	Good Correctly states which sample decomposed the most and whether it matched their prediction. Their discussion supported their conclusion and mentioned the physical properties of the materials.	Fair Correctly states which sample decomposed the most and whether it matched their prediction. Their discussion supported their conclusion, but did not mention the physical properties of the materials.	Poor Either incorrectly stated which sample decomposed the most or whether it matched their prediction or not. Their discussion did not support their conclusion and did not mention the physical properties of the materials.	Incomplete No discussion given.
Overall Presentation	Good Strong visual appeal and care given to construction and presentation of journal.	Fair Writing and drawings were accurate, but not a lot of effort was given to the overall presentation.	Poor Presentation is accurate, but writing is unclear and drawings/photos were poor.	Incomplete No effort to present documentation in journal form.
