Science: Physical Science

  Curriculum Standard 5c

Proficiency Standards
By the end of grade six students will be able to:

• Recognize and give examples of the various forms of energy, e.g. heat, light, sound, electrical, mechanical, magnetic, chemical, and nuclear.



• Observe and describe how one form of energy may be transformed into another.



• Design a simple experiment or demonstration to show the difference between potential and kinetic energy.

Proficiency Standards
By the end of grade ten students will be able to:

• Collect observations to show that transformations of energy involve the production of heat.



• Use basic measurement to study increases and decreases in an energy system to determine conservation of energy.



• Describe momentum and conduct an experiment to illustrate conservation of momentum.

  Curriculum Standard 5e

Proficiency Standards
By the end of grade six students will be able to:

• Observe and describe objects in motion, including vibration motion.



• Define the force which causes an object to undergo a change in direction or speed.



• Design a simple experiment which demonstrates the effect of gravitational force on an object.



• Describe or conduct an investigation which illustrates that for every action there is an equal and opposite reaction

Proficiency Standards
By the end of grade ten students will be able to:

• Formulate questions, design an exploration, and collect data about objects in motion.



• Demonstrate inertia as a property of an object which resists a change in motion and is directly related to its mass.



• Demonstrate the relationships among change in motion, applied force, and mass of an object.



• Identify friction as a force opposing motion.
