amazing maths

hi it is Levi from hornby high school and I'm writing about my challenge that I just  did here is what I did

I was trying to find away for farmers to find moister and puddle sin their paddocks and build shelters to stop cows getting infected heres a link to my slides.https://docs.google.com/presentation/d/13YWUoT-nq-jRaaIs6z0is5POfcml1dT_gwZrSZEWL7Y/edit#slide=id.p
I found out a solution and did my objective and designed a cow house

What I have learnt I learnt that cows can get infected hoof and that their are lots of simple ways to stop it
What did I like and dislike I liked the challenge it was fun making designs and doing it I didn't like how it took me a long time to think of and idea
Feedback I don't have any Feedback for this
sources and websites I used I used goggle wikipedia and tinker cad to do it
question do you think it was a good choice and do you think my ideas are good

safe temprature

it is important to keep your food at the right temp if its in the right temp bacteria will infect and spread all over your food keep it cold when its cold they sleep or freeze keep it hot to keep it hot to burn the bacteria and kill them of they double every 20 minutes that's allot if their is lots you will get very sick

Timo: timo where made from a forked brances with a flated blade some where strait and some wernt they where also used for loosning soil but the ko was for harder soils.

Kaheru: kaheru where made in sevral difrent forms they where made of wood and looked like a spade there are trhee tyeps of it they had short blades and long blades Kāheru were used not for heavy work such as breaking up soil or heavy digging but for lighter cultivation work such as loosening soil weeding.

bacteria

1 what do bacteria do to survive on our food
the right temp if the bacteria get cold they freeze or sleep in the hot they boil and burn to death. but if they are in the right heat they will survive and more bacteria will be on your food. every 20 minutes they will multiply and spreed to get them away keep your food under 4 or over 60.bacteria like condensation so they can get the nutrients from it
2 what 2 ways can we stop bacteria. keeping things at the right temp so they don't spreed and take over
or covering food tight so bacteria cant get in their to infect keeping them at the right heat will also stop them from growing
3 it is when the bacteria spreads to other foods and contaminates everything
4 the thermometer my blog lags and wouldn't let me type when I put the thermometer on their but I still got the temps
-18 freezer temp
-0 freezing point
2-4 fridge temp
4 to 60 danger zone bacteria will spread and contaminate
75 internal temp of chicken
80 reheating temp
100 boiling point
