We are studying physics in our 3-5 grade gifted class at Una elementary school in Nashville. One of our lessons is on force and inertia and we put a Barbie on a skateboard with and and without restraints to model wearing a seatbelt. When I am helping car riders I notice that many of our students are not in seatbelts, booster seats, etc. and would like to encourage the use of these restraints.
