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.
