- - - - Plug the rubber tube onto the gas tap. Make sure the airhole is closed.
        
        Light match before turning on the gas tap.
        
        Light the bunsen burner by hovering the match over the bunsen burner hole where the fire comes out area.
        
        Open the airhole to blue flame for heating
- - - - Hot = more heat energy
    - - Chemical energy
        
        Stored within a substance and released when digested or burnt
      - Elastic Potential energy
        
        Stored within stretched/compressed objects
      - Gravitational Potential energy
        
        stored in objects held above the earth
    - - Energy that allow objects to move
    - - Caused by charged particles
  - - - Type of energy changes; light to chemical with photosynthesis
    - - Energy moves from one place to another; from ball to rollling pin - bowling.
      - A lot of energy is lost as heat and sound
- - - - Eukaryote: Membrane-bound nucleus
        
        Plant Cell
        
        Cell Wall
        
        The structural formation that surrounds the membrane, the equivalent of bones in animals
        
        Chloroplasts
        
        Conducts photosynthesis, gives plants green colour
        
        Organelles found in animal cells
        
        Animal Cell
        
        Vacuoles
        
        Many small ones in animal cells, store resources/waste
        
        Mitochondria
        
        Breaks down glucose into energy (a molecule known as ATP), the formula is Glucose + Water = Carbon Dioxide + Water + ATP
        
        Nucleus
        
        Stores nucleolus with DNA and produces ribosomes
        
        Cytoplasm
        
        A jelly like substance in cells in which most chemical reactions happen
        
        Organelles
        
        Cell Membrane
        
        Lets certain things in cell, excretes
    - - Prokaryotes - Lacks membrane-bound organelles
        
        Archaea
        
        Bacteria
        
        Yeast
        
        Amoeba
  - - - Electron
        
        TEM (Transmission Electron Microscope)
        
        electrons are shot through specimen, hgh resolution of inside
        
        SEM (Scanning Electron Microsope)
        
        Electrons shot on surface, high resolution of surface (3D)
      - Light
        
        Less magnification, shoots light through specimen , surface
      - Stereo
        
        reflects light onto object, less magnification, surface
    - - Illumination - The bright torch that illuminates the slides
      - Ocular Lens - Put your eyes here
      - Stage - Surface to place the slides
      - Objective Lens - The three telescopes you twist to zoom in
      - Arm - The frame / carrying handle
    - - Place droplet of water on sample
      - Place sample on slide
      - Carry slide via edges
      - Sandwich using cover slip, no air bubbles
      - Secure wet slide with stage clips
- - - - gravity on earth is calculated as 9.8
