Scoring Rubric	Maximum Score - 13 Points

Point Criteria:

• Allow 2 points if at least two (2) out of three (3) entries in the data table are correct.
• Allow 1 point if only one (1) out of three (3) entries in the data table is correct.

Point Criteria:

• Allow 2 points if the students makes a general statement about a directly proportional relationship between speed and the amount of sand in the bottle.

  - The more sand in the bottle, the faster it rolls.

  - The less sand in a bottle, the slower its speed.

  - A bottle will roll faster with more sand inside than a bottle with less sand.

• Allow 1 point if the student restates a specific observation.

  - A bottle half full of sand rolls slower than a full bottle of sand.

Point Criteria:

• Prediction

  - Allow 1 point for predicting that bottle X is > 1/2 to full.

  - Allow 0 points if student implies that he/she looked into bottle X.

• Explanation

  - Allow 2 points for an answer comparing bottle X to bottle A or B.

  Sample of acceptable answers:

  • Bottle X rolls at a similar speed as bottle A or B and bottle A is full and Bottle B is 1/2 full.
  • It feels like the same weight as bottle A or B.
  • It rolls a similar distance from the ramp as bottle A or B.

  Allow 1 point (partial credit) for an incomplete explanation with no comparison to their data.

  • Bottle X rolled fast.

• Prediction

  - Allow 1 point for predicting that the bottle will roll the slowest of all the bottles.

• Explanation

  - Allow 2 points for an answer applying the data from bottles A, B, and C to the bottle 1/8 full.

  Sample of acceptable answers:

  • When there is less sand in a bottle, it rolls slower down an incline.
  • The trend in the data show that bottles with more sand roll faster than bottles with less sand, so a bottle 1/8 full will roll slowest.

    - Allow 1 point (partial credit) for an incomplete explanation with no comparison to their data.

Point Criteria:

• Prediction
  • Allow 1 point for an answer that is consistent with their data.
  • Explanation
    • Allow 2 points for an answer applying the data from bottles A, B to & C to the empty bottles.
  Sample of acceptable answers:
  
  - The data shows that bottles with more sand roll faster than bottles with less sand. So a bottle with no sand will roll slower than the rest.
  • Allow 1 point (partial credit) for an incomplete explanations with no comparison to their data.
    - The bottle rolled very slowly.
  • 0 points for an answer that states that the bottle will not roll.
  • 0 points for an answer that only verifies the prediction
