We have launched our inquiry science study of force and motion. Besides working cooperatively with partners, students are learning to question and wonder why balls move and what the difference between balls are and how they move. Throughout this study, we will pose questions for students to help guide their explorations with a range of balls. This past week, we made blind observations of how a table tennis ball and a rubber ball felt and then explored their movement, making observations by comparing and contrasting their features, sounds, and movement characteristics.
