Grade 4 "Metric Olympics" - 3rd Event Right Handed Marble Grab

Step 1: Estimate, in grams, the mass of the number of glass marbles you can pick up with your right hand.

Step 2: Using your right hand grab a handful of marbles from the bucket and place them on the pan balance.

 Step 3: Using the gram masses, place them on the other side of the balance until the arrow points at zero.


Step 4: Add the gram masses together and record that number on your record sheet.







Step 5: Calculate the difference between your estimate and your actual measurement.


Step 6: Repeat steps 1 - 5 for a second trial.






Great Pictures of Teammates working together and encouraging each other!
