Magnets
Magnetic Materials
Examples
Nickel
Steel
Iron
Lodestone
magnets that naturally existing
Cobalt
Magnet
They can only repel another magnet
Have poles
Magnetic force is the strongest at the poles
Magnetic force is weakest in the middle
Like poles
Repel
Unlike poles
Attract
Suspended Freely
Rest in the North- South direction (compass)
The North Pole will point to the North end of Earth
The South Pole will point to the South end of Earth
Non-Magnetic Materials
Classification
Non - Living
Living
human systems
Skeletal
Protect important organs.
Skull
Ribcage
Heart
Lungs
Gives the body shape and support
Digestive
WHY
We need to break down food into smaller piece, so the body can absorb it.
PARTS
Mouth
Teeth
Break the food down into smaller pieces.
Increasing the surface of the food
The digestive juice can digest the food faster.
Saliva
Moisten & Soften food
Easiler to swallow
Digestive juices are added
Digestion start here
Exits the Mouth
Some digested food
A lot of undigested food
Stomach
Muscular organ
Churn the food
Digestive juices were added
Watery - porridge like
Exits the stomach
The amount of undigested food will decrease.
The amount of the digested food will increase.
Small intestine
Digestion is completed
More digestive juices are added
Absorbs the digested food into the bloodstream.
The circulartory system then helps to transport this digestive food to all parts of the body
Exits the small intestine
No digested food
Only undigested food
Gullet
Exits the gullet
Same amount undigested food that leaves the mouth.
Same amount digested food that leaves the mouth.
why??
There was no digestive juices added in the gullet.
to bring food from the mouth to the stomach
Large intestine
Absorbs water from the undigested food
Spend a shorter time in the large intestine
Less water is absorbed
Watery stools
Spend a longer time in the large intestine
More water is absorbed
Dry and hard stools
Exits the large intestine
No digested food
Only undigested food
Anus
An opening to allow stools to pass out of the body
Circulatory
Heart
Blood vessels
Veins
Bring blood back to the heart
Low in oxygen
High in carbon dioxide
Respiratory
Parts
Lungs
text
Diaphgram
Muscle
the diaphragm moves downwards
air can enter the lungs
the diaphragm moves upwards
Pushes air out of lungs
Windpipe
Nose
Hair
Traps dust
Dust does not enter the lungs
Mucus
Helps to moisten the air
Helps to warm up the air
Muscular
Helps the bones to move.
