1. Definitions E Click for each heading then for the answer Effort =results

2. Energy Is the ability to do work Units = joules (J) What is work?

3. Echo Reflected sound Question on Echo – think of there and back  Speed = distance there +back Time taken

4. Egestion Removal of Undigested and unabsorbed food (e.g. fibre) (from the body) (from large intestine, through rectum + anus)

5. Element All the atoms are the same Listed on periodic table of elements E.g Iron is Fe

6. Ecology Study of the relationship between Living things and their environment

7. Excretion Removal of the wastes of metabolism (chemical reactions) from the body Three organs = Lungs (CO2 and H2O) Kidneys (urine = urea, water, salt) *Skin (sweat =water and salt)

8. Electrolysis A chemical reaction caused by electricity Water split into hydrogen : oxygen (2:1)

9. Electrolysis Hydrogen Oxygen Negative Positive Negative Positive Oxygen Hydrogen

10. Egg Female sex cell or gamete Made in ovary (both humans and plants)

11. Electron Negative particle in atom Orbits the nucleus in shells How many – look at atomic number (small)

12. Enzyme Catalyst made in living cell Amylase changes starch to maltose 

13. Earth wire Brings charge to earth Colour =yellow/green Safety Connected to TOP pin

14. Evaporation Liquid changes to a gas Used to separate a soluble solid from a liquid e.g. salt and water A= salty water B = wire gauze C = salt D= beaker E = water

15. Environment Everything that surrounds an animal or plant

16. Electronic Configuration How electrons are arranged in shells E.g Sodium = 2,8,1 (11 electrons)

17. Electronics Control of electric current in circuits

18. Electroplating Coating one metal with a layer of another using electric current Reduces corrosion Improves appearance Jewellery coated with silver

19. Electrical Energy Energy in moving charges

20. Equilibrium Balance Three states = stable, unstable, neutral

21. Do I know it?? Energy Echo egestion element ecology excretion electrolysis Egg Electron enzyme Earth wire evaporation environment Electronic configuration electronics electroplating Electrical Energy
