**Fire**
- Avoid wearing loose-fitting clothing while cooking as the sleeves can easily get caught on the elements.
- Keep flammable objects such as paper towels, pot holders, and tea cloths at a safe distance from the stove and oven.

**Burns/Scalds**
- Run cool tap water over thermal burns for 10 to 20 minutes.
- Do not put ice or butter on the burned area as these it doesn’t help and can damage the skin tissue.

**Chemicals**
- When working with chemicals it’s important to have good air flow in the area that you’re working in, to minimize exposure.
- Make sure you know what materials you’re working with. You need to be trained with specific chemicals, so you know what you’re doing with it to work safely.

**Slips/Trips/Falls **(i.e. how to prevent)
- Putting bags under desks so they aren’t in the way of your pathways in your unit/kitchen.
- Being aware of your surroundings and knowing where cords are to prevent rushing near those areas.

if you run, you will fall like minion dave did.

**Cuts **(i.e. how to prevent/how to treat)
- Preventative measures that can be taken to avoid a cut would be to stay focused while chopping/cutting and using a sharp knife.
- With a cut, you start with stop the bleeding with pressure then proceeding to clean around the wound. You then apply antibiotics and wrap the wound.

**Heavy Lifting**(i.e. of a bag of flour)** **
- Bend your hips and knees to squat down keep it close to your body
- Never lift a heavyobject above shoulder level as to not injure yourself or compress your spinal discs

**How to Prevent Food Poisoning**
- Wash cutting boards and knives with antibacterial soap and warm to hot water after handling raw meat, poultry, seafood, or eggs.
- Check the inspection scores of the places where dine out. You can check online reviews before you go to eat.

**Waste Management**
- Using rags instead of paper towels, in the kitchen is reducing waste as they can be washed and reused.
- Composting food scraps is a good way to cut down your carbon footprint as the less scraps end up in landfill, the less emissions are used in the landfill for them.

**Personal Hygiene**
- Keeping your hair and body fresh with showers and deodorant is vital to keep your kitchen sanitary and comfortable.
- To prevent any cross-contamination and make sure your food is up to standards, make sure your hands are always clean and hair is tied back.

The discovery of DNA is very vital to back up Darwin’s theory.

Darwin’s theory was that species change with time (very slowly). He also came up with the theory of principle common descent which includes the thought that modern organisms have been produced through evolution, every new organism comes from pre-existing organisms, that each species has descended from other species, and that all species have shared a common ancestor. That theory can be supported by DNA and fossil records by multiple pieces of evidence. With fossils, the lower layers of rock are older, scientists can determine the source of changes in an organism based on the layers in the rock. Evidence for this theory also lays in the science of embryology as now we can see that many animals and human embryos look very similar which proves that we are all distantly related to common ancestors. DNA is used in the confirmation of Darwin’s theory as, when it was examined, it allowed enough variation to be considered new generations, and with that information, evolution is now understood as a process of changes in the frequencies of stable variants.

Reflecting on the food waste in my life, I would say that I make changes in my life to reduce food waste, but ultimately, I could do better. At home, I reduce food waste by making my food in portions and saving any leftovers to eat later. At my home, we use compost and recycle by refunding cans and bottle and putting paper and plastic in the right place. At school, I also compost because the new bins make it easy to sort waste properly. I’ve also when out with friends that most places we go out to eat, also have some sort of recycling and compost system to follow. Despite my conscious efforts, like anyone, there’s room for improvement. Sometimes when I’m in a rush it seems simpler to just throw everything in the garbage cans. And when I make leftovers, food sometimes ends up getting wasted and thrown away. My brothers at home are not as eco-conscious as some and I often find things that could be recycled or composted, but I ignore it. To make progress I need a plan that’s easy to remember and keep me in line with producing less food waste and improve better organization when separating waste. I would also to learn the significance of food waste regarding the environment to give myself a clear reminder of why it’s important to reduce food waste.

The feasible action plan that I have chosen for myself is to label my leftovers and write down what leftovers I still have in my fridge, so I can easily plan my meals incorporating the leftovers into them. I’m going to try to reduce clutter in my fridge, so I can see everything because it usually disappears in the fridge until it goes moldy. I will continue to compost and recycle, as well as have a talk with my family about our food waste and how sorting things properly is important. I have also learned that the main problem with food waste involves the food going into landfills to rot, then producing methane gas which is 21 times worse for global warming than carbon dioxide, according to forbes.com.

This week in math 10, we learned about arithmetic sequences.

The point of using arithmetic sequences is to find the and to find the .

the is used to find the general form/ the equation that we use to find other terms in the sequence. for example, if we have numbers 16,20,24… the formula can be used to find the 25th term easily with algebra, instead counting each term one by one.

first we need to find the common difference. The common difference between numbers is how much the number adds by or subtracts by from term to term. The common difference is represented as (d). We use the formula down below find the Term N.

in our sequence from before (16, 20, 24…), our first term is 16, and our common difference (d) is +4.

This week in Math 10 we learned about Systems of linear equations.

3 different types of linear equations

– No solutions

– One solution

– Infinite Solutions

First – what is a solution of a linear equation? we can graph all proper linear equations and if we have an equation **of y=3x+4 and y=2x+3**

The solution – these two equations is the points where both of the lines when graphed touch when graphed.

No Solution – when graphed the lines would be parallel. two parallel lines never touch. You can also tell if two equations have no solution if you only look at the written equation. For example if both equations have the same slope and the y-intercepts are different, this means the equation will have no equation.

y=5x+2

y=5x+5

^ no solution. If you were to put these two equations into demos, you would end up with two parallel lines.

One Solution – when a linear equation has one solution that means when graphed, somewhere along the graph the two lines will cross, sort of like an X shape. Now when written out, if both linear equations have different slopes than that means they will cross at one point. Even if the y-intercepts are the same it doesn’t matter, only the slopes need to be different.

y=6x+3

y=8x+2

These two equations are will have at least one solution guaranteed.

Infinite Solutions – So a linear equation with infinite solutions means that when graphed, the two lines will be on top of each other. If written, you can tell two equations will have infinite solutions if the slopes are the same and the y-intercepts are the same.

y=4x+3

4x-y=-3

These two equations will have infinite solutions since they are on top of each other

this week in math 10 – we learned about the method of substitution.

substitution is the algebraic method of finding a solution for a system.

when doing the method of substitution – remember BFSD

B- brackets àexpand

F – Fraction àeliminate fractions

S – Sorting àorganize the numbers and like terms.

D – Divideànumber infant of Y

example:

x + 3y = 19 àrearrange àx = -3y +19

–> 4x- 2y à4(-3y +19) -2y = -12y + 76

= -10y +76

-10 -10

Y = 66

NOW USE Y TO SOLVE FOR X

X + 3y = 19 àx + 3(66) =19

3 x 66 = 198 + x = 19

X= -179

WEEK 13 – point slope form

This week in math 10 we learned about point slope form. Usually to find the slope formula you use the equation of

m= y1-y2/x1-x2 BUT to find point slope form you switch/move the equation to

m(x1-x2) = y1-y2

a good way to remember what you’re doing in point-slope form is to remember to ‘plug + play’.

That basically means to plug in the numbers into the equation and let algebra take over! Easy!

WEEK 12- slope formula

This week in math 10, we learned about slope formula. Slope formula is equal to

change y/change x

and that is equal to

y1-y2/x1-x2

Example: (3,7) and (-2,11)

Also keep in mind that 5/-4 would be equal to -4/5 , it all depends on how you do your equation
