Plot the Dot: A Graphical Approach to Density
Source Institutions
In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.
Pencil Drop
Source Institutions
In this demonstration, learners observe as a bottle is placed on a table with wooden hoop balanced on top and a pencil balanced on top of the hoop.
