Study Notes

Butterfly Species

  • Butterfly species are found exclusively in tropical regions.
  • Butterfly wing color patterns are used for camouflage and mating.
  • Butterflies consume nectar from flowers, tree sap, and rotting fruit.

Butterfly Lifecycle

  • The butterfly lifecycle consists of four stages: egg, larva, pupa, and adult.
  • Most butterfly species are nocturnal.

Simple Machines

  • Levers, springs, screws, and wheels are all examples of simple machines.
  • Simple machines can be found in more complex machines.
  • Sewing machines, bicycles, mortise locks, grain milling machines, and blenders are all complex machines.
  • Simple machines are used to perform a variety of tasks in complex machines.
  • For example, the mortise lock uses the following simple machines:
    • Levers
    • Latch bolt
    • Deadbolt
    • Latch spring

Sewing Machine

  • The sewing machine is lubricated with special oil to make it last longer.

Bicycle

  • The bicycle uses the following three simple machines:
    • Pulley
    • Wheel and axle
    • Lever

Grain Milling Machine

  • Grain milling machines are made up of a large wheel connected to the motor and a smaller wheel connected to the mill.
  • The large wheel rotates a belt that rotates the small wheel which is attached to the mill.
  • The mill is connected to a pipe that draws the flour from the mill.
  • A special cloth is attached to the pipe to prevent flour from spreading.

Mortise Lock

  • The mortise lock has two main parts: the outer and inner parts.
  • The inner part has the following simple machines:
    • Levers
    • Latch spring
    • Latch bolt
    • Deadbolt
  • The key has teeth that correspond to the specific lock.
  • When the key is inserted and rotated, the lever moves and releases space, allowing the deadbolt to unlock the door.

Blender

  • Blenders convert electrical energy into mechanical energy.
  • The base of the blender contains the motor, and the outer part of the blender has the jug, blades and lid.
  • The blades in the blender are part of the jug and are sharp.
  • The base of the blender should be wiped clean with a cloth because water can damage the motor.
  • The jug, blades, and lid are usually placed in a dishwasher but should be cleaned by hand if possible.
  • The blades should be dried before putting them back in the jug because they are extremely sharp.

Complex Machines

  • Complex machines are made up of more than one simple machine.
  • The grain milling machine uses a belt as a simple machine.
  • The bicycle uses levers for brake handles
  • The use of several simple machines allows complex machines to perform more complicated tasks.
  • Machines often make work easier and more effective.
