| Top , Left, Bottom | |
| What do the cell wall in plant cells do? | The cell wall support the tree and protect the plant from various things |
| What do vacuole do? | Vacuole stores food or nutrient a cell might need to survive. OR store waste |
| What are atom made of? | 99.9% Space |
| What is Mass number? | It is the top number and it tells us the number of proton plus neutron. |
| What is atomic number? | It is the number of neutron and located at the bottom of an element |

| LAW OF CONSERVATION OF ENERGY | Energy cannot be destroyed nor created. It can only be transferred from one form to another. |
| Native | not introduced, originally found in NZ, could have flown another country. |
| Introduced | Brought from another country |
| Endemic | Only found in NZ |
| Indigenous | Originally found in NZ but other countries may also have it. |
| Darwin's Hypothesis | 1 . More offspring are produced than will survive to adulthood. 2 . Not all individuals are the same - there is variation in a population. 3 . Some adaptations increase rates of survival. 4 . These adaptations can be passed to the next generations - they are heritable. |
| 3 Types of Erosion | Ice Water Wind |
| Why don't earth show any craters | It's been eroded. |
| Order of EMS | Radio wave Microwave Infra-red Visible Light UV ray X-ray Gamma Ray |
| Radio Wave | Uses to transfer info from one point to another via Electromagnetic radiation |
| Microwave | Will cook your food in minutes. Also used by astronomers to look at the structure of galaxies. |
| Infrared | Night vision goggles that picks up heat emitted by our skin and objects with heat. |
| Visible Light | Our eyes detect this. Fireflies, light bulbs and stars all emit this. What we see |
| Ultra Violet | This is emitted by the sun and are the reason for skin tans and burns. Can cause skin cancer |
| X Ray | A dentist uses this to image your teeth, and airport securities uses them to see through your bag, doesn't go through bones. |
| Gamma Ray | Very high energy electromagnetic waves. Use to sterilize surgical equipment and to kill cancer cells. |
| Green + Red | Yellow |

| Layers of teeth | Enamel Dentine Pulp Cavity - Nerve endings, blood vessel |
| What does Cornea do | Outermost transparent layer of eye. Begins Focusing |
| What does Pupil do? | The opening in the iris through which light passes. |
| What does Iris do? | The coloured portion of the eye that controls the size of pupil |
| What does lens do | This structure changes shape to focus light on the retina |
| What does retina do? | Contains sensory receptors for vision |

| Cone? | detects colour |
| Rod? | detect black and white |
| Vitreous humor? | Helps the eyeball keep its round shape and prevents it from collapsing |
| sclera? | Outer layer of the eye. Protects the eye and helps it keep its shape. |
| Aqueous humor? | Fills space between the lens and cornea. Plays a part in focusing light ray. |
