Students can use the Balancing Bird in the plan and to conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.
Students can use the Balancing Bird to make observations and/or measurements of an object's motion to provide evidence that a pattern can be used to predict future motion.
Students can use the Balancing Bird in the plan of an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object.
Students can use the Balancing Bird in an investigation to construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.
Students can use the Balancing Bird as an introduction to an investigation to use mathematical representations of Newton's Law of Gravitation to predict the gravitational forces between objects.
Students can use the Balancing Bird in an investigation to understand Center of Mass. It will maintain its equilibrium at nearly all times, and will recover from a great degree of upset. The bird's balance point is its beak. Students can further explore disrupting the state of equilibrium by adding paperclips to the wings, pressing down on one wing or the tail.
Students can investigate their own center of mass by standing on their left foot on a block of wood. What happens to their body when you ask them to reach left with their left arm? Their right arm and right leg will move to regain balance or Center of Mass. How does this resemble the Balancing Bird? Ask them how center of mass helps in riding a bike, skateboard, surfboard, or snowboard.
