Grade Level Indicator
1. Develop understanding of fractions as numbers
2. Build fractions from unit fractions.
3. Use equivalent fractions as a strategy to add and subtract fractions.
4. Understand ratio concepts and use ratio reasoning to solve problems
5. Analyze proportional relationships and use them to solve real-world and mathematical problems.
Key Idea 4: Energy exists in many forms, and when these forms change energy is conserved.
4.1j Energy may be stored in electric or magnetic fields. This energy may be transferred through conductors or space and may be converted to other forms of energy.
4.1k Moving electric charges produce magnetic fields. The relative motion between a conductor and a magnetic field may produce a potential difference in the conductor.
4.1l All materials display a range of conductivity. At constant temperature, common metallic conductors obey Ohm’s Law.
4.1m The factors affecting resistance in a conductor are length, cross-sectional area, temperature, and resistivity. 4.1n A circuit is a closed path in which a current can exist. (Note: Use conventional current.)
4.1o Circuit components may be connected in series or in parallel. Schematic diagrams are used to represent circuits and circuit elements.
4.1p Electrical power and energy can be determined for electric circuits.
Key Idea 5: Energy and matter interact through forces that result in changes in motion.
5.1n Centripetal force* is the net force which produces centripetal acceleration.* In uniform circular motion, the centripetal force is perpendicular to the tangential velocity.
How many revolutions would the right gear turn if the left gear turns three revolution?
They are provided with visual reasoning in the form of tangible gears kit, and imagery simulation with a software simulator that creates gears and simulates their movement.
