Discussions to this point have probably focused on comparisons between two characters. It can be much harder to talk about one character's speed when there is no comparison. Transition to graphing velocity by focusing on issues of constant speed and duration of travel. Extending to rates outside the context of motion will require additional attention. Another multiple choice activity helps students articulate what are critical differences.
Students work in small groups to create a final project that they then present to the class.
Students need to commit to a plan before beginning to make this most worthwhile. You should have a set of minimum requirements, such as a character must change speed and change direction. When students present their projects, invite the students to ask questions.
