Across
  1. 4. A material that does not let electricity pass through it
  2. 7. A simple machine that has a rod that goes through two wheels. It is used to move heavy objects
  3. 8. A simple machine that uses an object that pivots on a turning point called the fulcrum
  4. 10. A material that allows electricity to flow through it
  5. 11. A simple machine that has a wheel and something to wrap around it. It is used to lift heavy objects by pulling one end of the rope to lift the object on the other side of the rope
  6. 12. A circuit that has a gap so electric current can't flow through the whole circuit
  7. 13. A circuit where there is only one pathway for the electric current to go
  8. 14. A circuit that has no gap and allows energy to flow around it
Down
  1. 1. A component in a circuit that can open and close a circuit and
  2. 2. A circuit that has multiple pathways for electricity to flow
  3. 3. A flat surface that has one end high then the other. Used to slide objects upward instead of lifting them
  4. 5. A simple machine used to push objects apart.
  5. 6. A closed loop where electricity flows through with a energy source like a battery and a load like a lightbulb
  6. 9. A simple machine that look twisty and is used to hold objects together
