Grade Five, Goal 4

Forces and Motion in Technological Designs

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

Objectives

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.
