Flying Pig - High School Physics Enter rubric description
	Level 1 Grade D 1 pts	Level 2 Grade C 2 pts	Level 3 Grade B 3 pts	Level 4 Grade A 4 pts
FBD A free-body diagram of the pig is included.	Level 1 The pig, gravity and tension vectors are shown. (prelab question 1)	Level 2 level 1+ The horizontal and vertical components of tension and theta are shown. Formulas for each component are given. (prelab questions 2-6)	Level 3 level 2+ Derive an equation for v (prelab question 7).	Level 4 level 3+ Derive an equation for T (prelab question 8)
CALCULATIONS Find all the measured and calculated values.	Level 1 Find the centripetal acceleration.	Level 2 level 1+ Find the centripetal force.	Level 3 Level 2+ Find the tangential and angular velocities.	Level 4 Level 3+ Find the tangential and angular accelerations.
VELOCITY Compare theoretical and measured velocity	Level 1 Use measured r and L and a trig function to calculate theta. (Activity Instructions question 1-2)	Level 2 Level 1+ (Activity Instructions 3) Calculate the theoretical velocity using the equation you developed in step 7 of the prelab with the measured value of r and theta.	Level 3 Level 2+ (Activity Instructions 4) Measure the speed of the pig. Velocity is found by dividing the distance around the circle by the period.	Level 4 Level 3+ (Activity Instructions 5) Compare the two velocity values. Suggest sources of error.
TENSION Compare theoretical and measured tension.	Level 1 Find the theoretical tension in the string using the formula you developed in prelab question 8.	Level 2 Level 1+ Use a force sensor to measure the tension in the string.	Level 3 Level 2+ The Data Studio Force vs. Time graph was included.	Level 4 Level 3+ Percent error was calculated. Sources of error were explained.
POSTER The poster is visually appealing.	Level 1 Poor visual appeal	Level 2 Fair visual appeal	Level 3 Very good visual appeal	Level 4 Exceptional visual appeal
REFLECTION Peer Review	Level 1 Fair	Level 2 Good	Level 3 Very Good	Level 4 Award a 5 for superior. Award a 4 for excellent.
