Students will use an inquiry based approach to discover how things move. They will discover that a push and a pull are forces that put things into motion. They will also investigate how friction is a force that slows a moving object.
In this lesson, teachers show their students pictures of different events happening on Earth and asks if these events happen quickly or slowly, how students generated that judgment, and what happens on Earth after each event occurred. Students can explore a location around the school and record observations in their notebook about what events may be occurring in that location and if they are occurring slowly or quickly.
In this unit, students explore and explain the many different ways that an object moves and how its properties affect its movements. In one lesson ("In What Ways"), students predict and test their predictions on how different objects will move when gently pushed on their desks. In "Do All Tops Spin Alike?," students use different materials to construct their own tops and test its movements. "Making Objects Move" introduces the concept of acceleration and allows students to use different sizes and types of balls and other materials to build tracks that will be used to stop the ball at a certain location. "Playground Equipment" gives an engineering experience by engaging students in a competition with a given scenario and asking them to design, test, and re-design (if necessary) a functioning piece of new playground equipment (the terms "force," "motion," "gravity," and "simple machine" are introduced).
