Water bottle rocket
	Poor 1 pts	Fair 2 pts	Good 3 pts	Excellent 4 pts
Construction	Poor The rocket is poorly constructed, and the body of the rocket is destroyed during the rocket’s launch.	Fair The rocket is not well constructed, the nose or the fins are destroyed during the rocket’s launch.	Good The rocket is not well constructed but the nose and fins survive the rocket’s launch.	Excellent The rocket is well constructed that remains intact throughout the rocket’s launch.
Flight Performance	Poor The rocket is able to be launched.	Fair The rocket is able to be launched with airtime longer than 10 seconds.	Good The rocket is able to be launched with airtime longer than 15 seconds.	Excellent The rocket is able to be launched with airtime longer than 20 seconds.
Design	Poor The rocket does not display a scene that the group members all agree on. Students make no modifications to the design of the rocket to improve the airtime.	Fair The rocket partially displays a scene that the group members all agree on. Students make one modification to the design of the rocket to improve the airtime.	Good The rocket displays a suitable scene that the group members all agree on. Students make two modifications to the design of the rocket to improve the airtime.	Excellent The rocket displays a suitable scene that the group members all agree on. Students make more than two modifications to the design of the rocket to improve the airtime.
Video presented	Poor In the video, students show the material list or the process of making it without any explanation of the principle of bottle rockets and how they improve flight performance.	Fair In the video, students show the material list or the process of making it and try to explain the principle of bottle rockets and how they improve flight performance. The explanation is not completed but partially correct.	Good In the video, students show the detailed material list and the process of making it. Students explain the principle of bottle rockets and how they improve flight performance. The explanation is understandable, but with a small logic error.	Excellent In the video, students show the detailed material list and the process of making it. Students explain the principle of bottle rockets and how they improve flight performance. The explanation is logical and clear with no errors.
