Scrap Book Science
Breathing process of human
Excrete and defecate
Importance of excretion :-maintains health-maintains the pH, amount of water and mineral salts-regulates body temperature
Humans response to stimuli
tongue
Excretory organs of animals
Breathing structure of animals
Animal reproduce
Plants reproduce
Plants response to : -touch-water-Sunlight -gravity
How animals protect themselves from extreme weather???
Protection from danger (animals)
Specific characteristics that protect plants
Natural defence in plants : -latex-thick and hard skin/shell-fine hair-thorns-poisonous-bad smell
Measurement
tools : •rope•Match stick•Paper clips
body parts:•Foot•Cubit •Span
•Stride•Arm span
Straight line:•Measuring tape•Ruler
Curved line:•String •Ruler•Measuring tape
Area and volume of solid
Volume of liquid
Mass
• Electronic balance• Beam balance• Compression balance
Time • day• year• decades
• centuries
• 365 days = 1 year• 10 years = 1 decade• 10 decade = 1 centuries
• Pulse
• Wrist watch• Digital stop watch• Digital clock
Materials
Ability of materials to allow light to pass through it
To keep things warm and cool
Rust and non-rusty
How to prevent rusty???-coat with grease & oil-coat with plastic-coat with other metal-coat with paints-cover with plastic or paper
Natural and man-made materials
Reduce, reuse and recycle
Solar system
Other components of solar system
Human limitation
Microorganisms Disease caused by microorganisms : -Mumps-Measles-Chicken pox-AIDS
Fruits dispersal

Sources of energy
Forms of energy : -electrical energy-potential energy-Heat energy-Kinetic energy-Light energy-Sound energy
Source of electricity :-dry cell-accumulator-solar cell-hydroelectric power-dynamo-mercury cell
Renewable and non-renewable
Circuit
Series circuit Parallel circuit
Light
• Light travels in a straight line• Light cannot pass through an opaque object• Light can be reflected
• Light source-object (increase) = decrease• Light source-object (decrease) = increase• Object-screen (decrease) = decrease• Object-screen (increase) = increase
Heat
States of matter

constellation
Uses of constellation :1.To indicate time or seasons2.To show direction
Occurrence of day and night
axis
daynight
Phases of the moon
Factors that affect the strength and stability
Animals that live in groups and solitary
Competition among living things
Effect of force :1.Change the shape2.Change the speed3.Stops a moving object4.Move a stationary object5.Change the direction of the moving object
Friction
Movement
• Distance : speed X time• Speed : distance time• Time : distance speed
