Uses and Examples of static electricity

What is Static Energy;
Static energy is stored energy or potential energy.Static energy is when electrical charges get charged on the surface of objects. These charged remain on an object untl they are released to the ground or just fade away naturally.






- Shocking a person; Rubbing materials against one another can transfer negative charges, or electrons. For example, if you rub your shoe on the carpet, your body collects extra electrons. The electrons hold on to your body till they are released again.Therefore if you touch a someone they get shocked.

Respiratory System, Asthma& smoking

Respiratory System:
Your body is able to store what ever amount of energy it needs but it can't store any amount of oxygen. And so since you can't store the amount you need of oxygen your body takes it in a process called breathing which is the most important function in the respiratory system. We all have two lungs in our ribs that are surrounded by the ribcage and under it the Diaphragm. Every time you inhale the diaphragm contracts and moves downward and so your ribcage expands which produces air pressure inside of your lungs. And so when you take a breath the air comes in from your mouth or your nose and takes it way to the trachea and the lungs. Inside the lungs, the air moves to a smaller tubes which are called bronchial tubes. And so the air spreads to Alveoli which is surrounded by blood which is called Capillaries. From the capillaries the air moves to the blood. And so it gets rid of the Carbon Dioxide which is in your cells and takes it way through the blood into yours. And last the Diaphragm relaxes and exhales the gas out.

Asthma:

People who suffer from asthma feel tightness in their chest, they cough alot and they have a short breath. And so when you breathe the air goes to the tiny sacs(alveoli), which takes the oxygen in and kicks out the Carbon Dioxide. And so we all know that the air we breathe is not always healthy and that clean. What happens during an asthma attack is that when the air wants to get out dust inters and over reacts which will increase the chemicals that will cause the air paths to narrow that will make it much harder to breathe. And so that's why people that have asthma always have their inhalers with them to make it easier for them to breathe.


Smoking:
Smoking is really bad for you and can give you a heart disease easily. Cigarettes are made of a plant which called tobacco and many other chemicals. If instead of putting air in your lungs you put smoke in them it will damage them and they'll start turning black. this will give you a hard time breathing especially if your and athlete. Our a period of time smoking it can cause cancer to your lungs. Nicotine is a very bad chemical that is found in cigarettes which may cause you serious blood problems.

Mouth

The Mouth
When you put food in your mouth, it makes saliva which starts digestion. And so there are two parts of digestion, 1)Chemical , 2) Mechanical. What happens in the chemical part is that the enzymes change starch into sugar. And in the mechanical part it breaks down the food into small pieces. And so then the food slides to the esophagus.

Reflection

In term 2 Afra achieved a 5 and earlier in term 1 she got a 6. Instead of improving and learning from her mistakes she went down. Another point about her grade going down is that term 2 is harder than term 1 because instead of looking at term 2 grades the system this year has changed and anything in term 1 is affected and counts for term 2. Afra has faced difficulties and that clearly shows from her grade. She should really use her time wisely and come ask me if she has any questions. Also submitting homework on blogger really affected her grade. She was warned more than once but she decided not to listen. Afra could improve and achieve even a 7 if she focuses more in class next term. I wish her all the best!

Digestion Parts

Mouth;

Mechanical or physical digestion – chewing food and breaking into small pieces.

Saliva - Chemical digestion and breaking down carbohydrate.

- Slimes your food so it slides food down your esophagus

Esophagus

- Squeezes the food down to the stomach.

Stomach

- Stores food

- Mixes food (Mechanical digestion)

- Makes acid in order to help break down protein

Enzyme pepsin – Breaks down protein

- Ph-2 in your stomach when you get food inside.

Small intestine- Fats (lipids)

- Carbohydrates

- Proteins are all finished getting digested.

All of these are observed into your blood (small intestine)

Pancreas;

Makes all the important enzymes that go to small intestine to digest fats, carbohydrates and proteins.

Makes insulin in order for your body cells to suck up sugar (glucose).

Liver; greenish yellow

-It makes bile which is stomach in your gall bladder and sent to your small intestine.

- It filters the blood from your small intestine.

- Stores sugar so it can be released.

Forces and laws

First law;
Things in motion will stay in motion and keep going until another force stops or acts on it.

Second law;
Force = mass times exelartaion .. heavier things go slower and slower things go faster when the same amount of force is acting on it.

Example;
2 skates one is heavier than the other so when you push both with the same amount of force the lighter one will go further unlike the heavier one.

Food Web in the Sagebrush steppe ecosystem

1a) All carnivors and harbivors eat plants. In this food web case the insects prongnhorn and other grazers, squirrels and other small residents.

b) Snakes are eaten by badgers and raptors.
c) Insects are eaten by bats, lizards and small reptiles.
d) Mountain lions are not eaten by anything because they are top preditors.

2) The pronghorn and other grazors and lizards and reptiles will increase , but so will the raptors and mountain lions because there will be more food for them.

3) The pronghorn and other grazors will decrease because too many mountain lions will be eating them.

4) They will make tte soil more full useful neutrons and all animals that eat it .

Van Helmonts Experiment

Van Helmonts Experiment
Afra Al-Kaabi 8E


1. A quantitative attribute is one that exists in a range of magnitudes, and can therefore be measured. The experiment relates to quantitative because it is based on measuring the weight of the soil and the weight of the plant.

2. I think that plants grow because they live in soil and plants get bigger because of the soil they ate.

3. My hypothesis is wrong because in the story they prove that the soil after 5 years is still the same weight despite the small changes from 90.9 kg to 90.8kg.

4. Van Helmont tried to control the variables for this experiment by trying to see if there was a difference with the soil weight after 5 years.

5. If plants did really eat soil then the soil weight number would have been less after 5 years of time because the plants would’ve ate the soil.

6. 5 years is a long period of time. By then I think the plant takes out the mineral salt from the soil.

7. Plants get their weight from water and carbon.

8. If I redone this experiment I would’ve measured the water I put in because maybe that would make a difference to see if plants actually drink the water and not eat the soil.








Plant questions and Wordle
Afra Al-Kaabi 8E

1. A vascular plant is a plant that has two networks of tubes in their roots, stems and leaves. One network of tube carries water and the other carries food to the rest of the plant.

2. All vascular plants share a structure called roots, stems, and leaves. Lots of plants have their own specialized version an example would be the petals of the flower.

3. Roots are designed to pull water and minerals from whatever material the plant sits on. Roots also give support for plants in the form of being an anchor in the soil.

4. The two jobs of a stem are they transport food and water and acting as support structure secondly it holds the flower up, so that it can be seen by insects and pollinated.It also holds the leaves up so they can get plenty of light.


5. The xylem of a plant is the system of tubes and transport cells that circulates water and dissolved minerals. As a plant, you have roots to help you absorb water. If your leaves need water and they are 100 feet above the ground, it is time to put the xylem into action! Xylem is made of vessels that are connected end to end for the maximum speed to move water around. They also have a secondary function of support. When someone cuts an old tree down, they reveal a set of rings. Those rings are the remains of old xylem tissue, one ring for every year the tree was alive.

6. Phloem transport sugar and other kind of molecules which plants have created.

7. Chlorophyll is a compound which grabs the sunlight and starts a whole process. It is actually a varied compound.

8. In photosynthesis carbon dioxide and water combine with light to create oxygen and glucose.
