        Goals for the Understanding of Balls and Ramps

        Teacher Heidi Fessenden converses with her first grade students while they conduct an investigation on marbles rolling down ramps. The students test whether the size of the marbles affects how quickly they roll down the ramp. Fessenden informally assesses their learning while they conduct the tests. Her teaching goal is not necessarily to have the students reach the right answer, but to have them practice scientific processes and communicate their thinking.
