Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions. Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system. Apply scientific ideas to design, test, and refine a device that converts energy from one form to another. [Assessment Boundary: Assessment does not include quantitative measures of changes in the Use evidence to construct an explanation relating the speed of an object to the energy of that object. Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved. Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost. Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.
Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem. Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool.

Each team invention will test potential and kinetic energy. Don't let the force of gravity keep you down. Catapults and Trebuchets will breach a castle. Experiment with different projectiles, arm lengths and other variables to build and launch with a siege machine.
