• Conservation of Energy
• Kinetic Energy
• Potential Energy
• Thermal Energy
• Energy
• Friction

Description

Learn about conservation of energy with a skater gal! Explore different tracks and view the kinetic energy, potential energy and friction as she moves. Build your own tracks, ramps, and jumps for the skater.

Sample Learning Goals

• Explain the Conservation of Mechanical Energy concept using kinetic energy (KE) and gravitational potential energy (PE).
• Describe how the Energy Bar and Pie Charts relate to position and speed.
• Explain how changing the Skater Mass affects energy.
• Explain how changing the Track Friction affects energy.
• Predict position or estimate speed from Energy Bar and Pie Charts.
• Calculate speed or height at one position from information about a different position.
• Calculate KE and PE at one position from information about a different position.
• Design a skate park using the concepts of mechanical energy and energy conservation.

This interactive learning activity is aligned with Solomon Islands Year Seven Science Curriculum:

• Strand: Energy and Changes
• Sub-strand: 7.4 Energy
• General Learning Outcome:
  • 7.4.2 know that there are different forms of energy (k)
  • 7.4.3 be able to show that energy can change from one form to another (s)
  • 7.4.4 know that the total amount of energy remains the same during transformations (k)
• Specific Learning Outcome:
  • 7.4.2.1 identify and describe different forms of energy; heat, sound, elastic, electrical
  • 7.4.4.1 state the law of conservation of energy; “Energy cannot be created nor destroyed, but can be changed from one form to another.”
