My List Of Sciene All Around Me

This is for my homework. My challenge is to find as many different ways in which science is happening all around us. I have to Make a list and describe the processes. These are mine.

1. Walking to school.
2. Listening to music.
3. The TV. We can now watch cartoons and the news on a big screen.
4. Internet. People used to have to search it up in encyclopaedias.
5. Computers. It is electronic.
6. I phones. They are electronics.
7. Radio. We can listen to the news.
8. Microwave. They used to have to warm up their food over a fire.
9. Freezers. Before our defrosting freezers people had to scrape out the frost from the freezers.
10. Fridge. Now we can keep our food cold.
11. Oven. It used to be over a fire now we use gas.
12. X-rays. Now the dentist can check your teeth and the doctors can check your bones.
13. Hospital gear. Now the doctors can use devices and special machines.
14. Cars. The cars are moving to electric rather than petrol.
15. Digital watches. We now don't have to rewind the clock everyday and we use very thin batteries.  
16. Lights. Lights now use electricity so we don't have to keep using matches.
17. Solar panels. All you have to do now is put them under the sun.
18. Weed killer. Scientifically formulated to kill weeds and let the grass grow.
19. Medicine.  We don't have to use plats anymore.
20. Robots. Scientifically made so we don't have to do things our selves.
21. Traffic lights. They make less crashes.
22. Magnifying glass. It helps read small words from a further distance.
23. Windows. They allow to keep the warmth in and still be able to see through.
24. Ear phones. You can listen to anything on your phone without other people hearing.
25. Head phones. You can listen to anything on a computer without other people hearing.
26. Phones. You can talk to people that are far away from you.
27. Toilet paper. Toilet paper used to be used with leaves and stones.
28. Pens. People used brush and ink.
29. White boards. People used to use chalk boards.
30. White board pens. People used to use chalk. 
31. Smart boards. Now we can show lots of people at the same time off a big screen rather than a small screen on a computer.
32.  Paper. People used to write on fresh bamboo.
33. Wax. Scientist made wax for candles.
34. Mirrors. They reflect off the sun.
35. Water purifier. The scientist made a machine that makes seawater or salty water into plain drinking water.
36. Calculator. It was to hard for them to do it in their head.
37. Torches. People use it for light instead of using fires and torches. (Also lamps as well).
38. Washing machine powder. Scientifically formulated to get dirt and stains off clothes.
39. Power lines. They transport electricity.
40. Aeroplanes. They have aluminium wings. The pilot also has to work out how much fuel in the wings, that is science.
41. Air Conditioning. It uses science to work out if the air conditioner needs hot or cold air.
42. Opening heavy jars. It uses power and energy.
