Wood Block

Blocks should be sufficiently large and heavy that students can feel the forces they generate. The wood should be reasonably homogeneous so the centroid of each block is close to its geometric center. All edges and corners should be rounded slightly (3mm radius) to increase durability. All surfaces should be flat and smooth and coated with a waterproof finish. Our blocks were square in cross-section and 4 times as long as they were wide (40x40x160mm).

Quantity: 4 blocks per kit.

Ruler

To measure the depth of the sea of marbles at which failure occurs.
