Goal 4: The learner will conduct investigations and use appropriate technologies to build an understanding of forces and motion in technological designs.

• 4.01) Determine the motion of an object by following and measuring its position over time.
• 4.02) Evaluate how pushing or pulling forces can change the position and motion of an object.
• 4.03) Explain how energy is needed to make machines move: Moving air, Gravity.
• 4.04) Determine that an unbalanced force is needed to move an object or change its direction.
• 4.05) Determine factors that affect motion including: Force, Friction, Inertia, Momentum.
• 4.06) Build and use a model to solve a mechanical design problem: Devise a test for the model, Evaluate the results of test.
• 4.07) Determine how people use simple machines to solve problems.
