Significant Assignments:

Experiments to investigate what happens weight of an object under water

Experiments to investigate weight of a floating object

For the above, students calculated the densities of various objects using valid measurements, made and analyzed graphs, and studied the relationships between different variables. They also did varied problems to apply what they had learned.

Students further investigated the relationship between mass, volume, and density through graphs. They calculated slopes and wrote linear equations.

Significant Activities or Projects:

Experiments to test how hulls of different shapes move on water, relationship between mass and speed, relationship between mass and acceleration, relationship between force and speed, relationship between force and acceleration.

Sample PBATs:

Design and construct boats to achieve certain purposes (e.g., speed boat, cruise ship, barge, fishing boat, canoe, etc.)

Design experiments to test if the boats achieve their purpose.
