iRubric: Catapult Project rubric

Mechanism could not be built using procedural instructions the group provided.

Procedural instructions are missing a few key details to be reproduced again.

Procedural instructions are useful and mechanism could be built again somewhat easily.

Extremely detailed procedural instructions which would make for an EASY rebuild.

No entry OR provides very little detail about several aspects of the planning, construction, and testing process.

Little to no test data gathered.

Records and data provides some detail about the planning, construction, testing, modification, and reasons for modifications.

Some test data gathered, but not recorded in an appropriate manner.

Records and data provides a complete record of planning, construction, testing, modification, and reasons for modifications.

Data gathered, but could have paid a little more attention to data gathered to make modifications.

Records and data provides a complete record of planning construction testing, modifications, reasons for modifications, reflections about strategies used/ results.

Completed early and used that time to analyze data and make necessary adjustments to be successful.

Mechanism was not completed on time, and/or group members did not use class time appropriately.

Mechanism was completed on time, but could have used more time to make some major improvements. Some time was wasted. Did not use testing time and data to make improvements.

Mechanism was completed on time, but could have managed time a little better to make minor improvements that were needed.

Awesome use of class time. Extremely productive and the completed mechanism reflects the large amount of work put into it.

Inappropriate materials were selected and contributed to a mechanism that performed poorly.

Appropriate materials were selected, but more care could have been taken in planning how to use them.

Appropriate materials were selected and there was an attempt at creative modification to make them even better.

Appropriate materials were selected and creatively modified in ways that made the mechanism the best that it could be.

Group does not illustrate much understanding of scientific principles or the scientific method during the construction and modifications.

Group members indicate some understanding of scientific principles and the scientific method during the construction process.

Group members indicate relatively accurate understanding of scientific principles and the scientific method during the construction process.

Group members indicate a clear and accurate understanding of scientific principles and the scientific method during the construction process.
