        Making Observations of Balls and Ramps

        In this video segment from Teaching Elementary Physical Science, teacher Heidi Fessenden encourages discussion about observations of physical phenomena. She asks her first-grade students to share their observations and offer explanations about the behavior of marbles rolling down ramps. Fessenden uses questioning and offers key terms to focus the students' attention on important observations and to help them express detailed descriptions.
