Properties of matter s7-8:9(questions 2,3,4,5,7,10 &11)

Accurately measures and calculates the density of the objects AND Data includes correct units AND Demonstrates understanding of density with clear and adequate detail (all answers correct and supported with evidence).

Accurately measures and calculates the density of the objects AND Data includes correct units AND Demonstrates understanding of density with some details or evidence missing in some answers.

Minor errors in the measurements or calculations OR Units not included or incorrect OR Demonstrated partial understanding of density (some answers incorrect or many answers not supported with evidence).

Incorrect measurements and/or calculations AND Units not included or incorrect AND/OR Demonstrated poor understanding of density (several answers incorrect).

Predicting & Hypothesizing s7-8:2(question 1)

 

Prediction is reasonable in terms of evidence AND Response includes an explanation comparing the relationship between the density of the object and the liquid its submerged in and whether that object will sink or float.

Prediction is reasonable in terms of evidence but may not include an explanation or the explanation is incomplete.

Prediction is not reasonable or is missing.

Analyzing Data s7-8:6(question 8)

 

Accurately compares the densities calculated to the densities in the table AND Accurately describes possible experimental errors AND Explains how these errors may have affected the data in the investigation.

Inaccurately compares the densities calculated to the densities in the table AND/OR Accurately describes possible experimental errors BUT Incompletely or inaccurately explains how errors may have affected the data in the investigation.

Identifies irrelevant experimental errors.

Explaining Data s7-8:7 (question 9)

 

Reflection on hypothesis is correct (yes/no answer) AND Response accurately describes the relationship between the density of an object compared to the density of the liquid it's in in order for the object to sink AND All claims are supported with data from the investigation.

Reflection on hypothesis is correct (yes/no answer) AND Response accurately describes the relationship between the density of an object compared to the density of the liquid it's in in order for the object to sink BUT Claims are not supported with data from the investigation

Reflection on hypothesis is incorrect AND/OR Response either inaccurately or incompletely describes the relationship between the density of an object compared to the density of the liquid it's in in order for the object to sink
