Standard(s) Taught 

SC.6.P.13.1 Investigate and describe types of forces including contact forces and forces acting at a distance, such as electrical, magnetic, and gravitational.
SC.6.P.13.2 Explore the Law of Gravity by recognizing that every object exerts gravitational force on every other object and that the force depends on how much mass the objects have and how far apart they are.
SC.6.P.13.3 Investigate and describe that an unbalanced force acting on an object changes its speed, or direction of motion, or both.
SC.6.P.12.1 Measure and graph distance versus time for an object moving at a constant speed. Interpret this relationship.
SC.6.N.1.1 Define a problem from the sixth grade curriculum, use appropriate reference materials to support scientific understanding, plan and carry out scientific investigation of various types, such as systematic observations or experiments, identify variables, collect and organize data, interpret data in charts, tables, and graphics, analyze information, make predictions, and defend conclusions.
SC.6.N.1.4 Discuss, compare, and negotiate methods used, results obtained, and explanations among groups of students conducting the same investigation
SC.6.N.1.2 Explain why scientific investigations should be replicable.

Learning Targets and Learning Criteria 

Students will: • investigate and describe types of forces, including: o Forces at a distance: electrical, magnetic, and gravitational o Contact forces: normal, applied, friction
Students will: • explore the Law of Gravity by recognizing that every object exerts gravitational force on every other object and that force depends on how much mass the objects have and how far apart they are
Students will: • investigate and explain how an unbalanced force acting on an object changes its speed or direction of motion (or both)
Students will: • measure and graph distance versus time for an object moving at a constant speed • analyze and interpret graphs and data tables of distance and time for an object moving at a constant speed
Students will: • design an investigation to test the effect a variable (mass, tire size, ramp incline, etc.) has on the speed of an object using a minimum of 10 trials o collect data and organize it in a table o analyze the data through graphing o draw conclusions from the analysis about the speed and position of the object as well as the forces acting on it • discuss and compare methods used, results obtained, and proposed explanations among groups of students conducting the same investigation • explain why scientific investigation should be
