Chemistry Unit Reflection

Before, I wondered why we would do chemistry, as I thought I wouldn't need it in life. I thought that chemistry was just a unit, that it wouldn't impact our lives at all. After this whole unit, we have done many experiments. Until today, I didn't realize what the good in chemistry was. I thought it was just something done in a lab, but it's not.

Now I know that chemistry isn't only super fun, it is also super helpful. You can figure out whether something is an acid or a base, and you know that chemistry is involved in many around the house thin. Chemistry is an amazing unit, my personal favorite, and we actually use it a lot in life. I know I will never think that chemistry is pointless again.

Modeling Integer Operations

In this blog post we are going to show you how to add, subtract, multiply and divide integers.

Addition

6 +  -4  = 2

For addition, we first put down 6 positive chips to show the first part of the equation. Then, we place 4 negative chips to show the second part of the equation. We put the negative chips underneath the positive chips to make 4 zero pairs which gives us 2 as the answer.

Subtraction

4 -  -3  = 7

For subtraction, you first have to place 4 positive chips. Then, you have to add 3 zero pairs which still makes the total of the 4. Next, you have to subtract -3 from 4, or 3 -3 chips, which makes positive 7 as the answer.

Multiplication

-4 * -2  = 8

For multiplication, you first want to make 4 groups, but instead of -2 in each group, you want to put 2 zero pairs in each group. You do this so that you have groups to take away. Then, you want to take away 4 groups of negative 4 to get positive 8 as your answer.

Division

-84 = -2

For division, you first have to get 8 negative chips. Once you got your chips, you want to divide the chips into 4 equal groups since the equation is -84. Then, you count up however many negative chips are in each group to get -2 chips as the answer.

'MY PLATE' VIDEO

1. The 5 main food groups are fruits, veggies, grain, protein and dairy.
2. Whole grains are important because they give you energy, more than just grains.  Whole grains give you more energy.
3. Breakfast is the most important meal of the day because it gives you energy to keep you going throughout the day. You could have a smoothie for breakfast because it could give you fruits, veggies and dairy
4. Some great snacks are almonds, olives, blue corn chips and whole grain crackers and cheese.
5. Some  good fats are blue corn chips, olives and avocado.
6. Each day, you should have below 6oz of juice.

My Plate Project Planning

1. Fruits, veggies, grain, protein and dairy.
2. Fruits-apple, veggies-carrots, grain-double fiber bread, protein-chicken, dairy-milk.
3. My mom is allergic to  strawberries, kiwi, maybe pineapple and other fruits. My dad and sister try to only eat only healthy food. Besides that were all good.
4. My mom because she is in charge of the kitchen, and she knows how to make a lot of different healthy-ish meals.
5. The nearest grocery store is Fair Price or 2 different Cold Storages, all in walking difference, and my mom will help/shop with me.
6. Be careful when cutting, keep the stove off, stay away from big flames, and be careful of knifes.
