Microscope observations:
Tap water I saw little bubbles and little things moving things, I am not very sure what they really are.

Pond water This time I saw more little bubbles and they they look kind of brown. I also saw more cells than the tap water

Green Leaf

We saw green dots and a red dot in the middle they look like flowers when they form, but they look a bit burry

Dead Leaf I saw little water cells, some grey hole and the surface has little bubbles

Conclusion: I think that everything seems to be made out of smaller piece of bubbles, air and tiny dots of water that we can't see with a naked eye

Human cell Challenge
= = = =
 * How do human cells get the things they need to survive? Human cells need water to survive, water provide air food etc. All those things are provided in our body. Correct


 * How do they get food/oxygen? They get food from the water they live in. Correct


 * How do they get water?Water is their habitat with out it they wouldn't be there, even the smallest dot of water could be useful to these cells. Correct

How do they get rid of waste?They get rid of waste in the water and the water takes it with our waste and so the organism's waste comes out with our waste. Correct

CIRCULATORY SYSTEM REVIEW

Answer these questions: 1. What are the basic needs of all living cels?The basic needs that all living cells need are water, air (Oxygen, Carbon Dioxide), food (sugar) and waste disposal. Correct OK!

2. How do the cells in multicellular organisms get the resources they need to stay alive?They get resources from where they live, like the organisms that live in us we provide the water which is the blood, the air that we breath in. Multicellular organisms have specialized structures to transport resources to cells x 3. What is the main function ??? of the left side of the human heart? The Main function i s the Left Ventricle and the left arteries. Correct x 4. What is the main function ??? of the right side of the human heart? The main function on the right side are Right Ventricle and the Right Atriums. Correct x 5. What is the function of the red blood cells?<span style="color: rgb(255, 26, 26);">The function of the red blood cell is to carry oxygen from the lungs to the cells, and to take away carbon dioxide from cells to the lungs. Correct 1/2 6. What are the main kinds of blood vessels and what functions do they perform? <span style="color: rgb(255, 26, 26);">Blood vessels transport blood throughout the body, 3 of the major types of blood vessels are the arteries, the arteries carry the blood away from the heart, the capillaries, capillaries is the exchange of water and chemicals between the blood and the tissues, and last the veins which carry blood back from the capillaries back towards the heart. Correct OK! 7. Describe what happens when blood flows through the lungs.<span style="color: rgb(255, 26, 26);"> When blood flows through the lungs the body ether gets rid of carbon dioxide or receives oxygen. Correct 1/2 8. Describe what happens when blood in capillaries flows past cells.<span style="color: rgb(245, 0, 0);"> Well it gets what it needs.To stay alive. <span style="color: rgb(132, 0, 250);">It exchange gases while the red blood cells are sliding pass x

Food, water, gas exchange, and waste removal! 2. Blood flowing through the circulatory system delivers nutrients and removes waste 3. It collects blood from the lungs and pumps it to the body tissues. 4. It collects blood returning from the body tissues and pumps it out to the lungs. 5. They carry oxygen from the lungs to the cells, and carbon dioxide from the cells to the lungs. 6. Arteries carry blood away from the heart. Veins carry blood to the heart. Capillaries touch all cells and carry out gas exchange and nutrient delivery. 7. Red blood cells release carbon dioxide for elimination and pick up oxygen for delivery. 8. Cells take water, food (sugar), minerals, and oxygen from the blood and transfer wastes to the blood.

CIRCULATORY & RESPIRATORY SYSTEM

 * In comes the new oxygen out goes carbon dioxide
 * The wild pipe holds little air sacs that holds air and send it to the heart and then the cells.
 * Whit blood cell helps your body from viruses
 * Blood heels wounds
 * Blood needs to be the same type to be donated
 * Blood gives you protean
 * The Circulatory and Respiratory doesn't need to warm up for sports.
 * Reed blood cells transports oxygen throughout out his body
 * Right side sends out and will come back
 * Left side of the heart has to leave the body.
 * Arteries are like highway it gets smaller and smaller.
 * Plasma contain protean
 * 2 million blood cells are made per sec

Discussion After Video The platelets form fibrin that scabs the wounds and stop the bleeding. it stops the escaping blood for to much blood loose.
 * 1) The heart rate increases in speed.
 * 2) To supply the red blood cell with oxygen to give to the cells around the body.
 * 3) It helps the cells need to be oxygenated so they can keep active and keep working and to get rid of carbon dioxide.
 * 1) The white blood cells defend your body from diseases

Heart Dissection
First we cut open the right side of the pig's heart, then we started investigating the right atrium and the right ventricle, we then found the tissues on the side, then we started searching for the valves, we saw 2 of them on the right side. Then we cut the left side of the heart and started invested the left arteries and the left ventricle, we also found the 2 other valves, we also had some time to take pictures of the pig's heart.

Digestive & Excretory System

 * Silva and the teeth does the first job in the digestive system, the teeth's brakes down the food while the silva


 * The esophagus squeeze the food along the way to the stomach


 * The stomach has to cover it self with a thick layer of mucus to keep the hydrochloric acid in side the stomach from damaging itself


 * The food will be gone except fore some parts the acids couldn't brake down.


 * Both hydrochloric acid and pepsin are need to break down food


 * Kidneys

**CELERY OBSERVATIONS AFTER 1 DAY BUT //BEFORE// MEASURING <span style="font-weight: normal; font-size: 70%; color: rgb(0, 151, 255);">1. What is the general condition of the celery stalks compared to yesterday? It has a greater mass today and you could really tell the water has decreased. 2. How did the water in the vial change from yesterday? <span style="color: rgb(0, 151, 255);">It changed a bit from the amount to the color. 3. What do you think happened to the water? <span style="color: rgb(0, 151, 255);">The celery might have absorbed some or it might have evaporated.

RED DYE CELERY OBSERVATIONS <span style="font-size: 70%; color: rgb(0, 151, 255);">1. What did you observe when you first looked at the red-dyed whole celery stalk? The veins and stem turn red because of the red die. 2. What did you observe when you then looked at the cross section of the celery stalk?<span style="color: rgb(0, 151, 255);">We saw red dot that are veins of the celery. 3. What do you think the red dots are in the celery stalk cross section? <span style="color: rgb(0, 151, 255);">They are veins that has the red die in them so they stick out. 4. What is the relationship between the red dots and water in the celery stalk? <span style="color: rgb(0, 151, 255);">Because the water is red so the veins are red because it absorbs red dye so it turns red. ****MY CONCLUSIONS FOR CELERY EXPERIMENT B: <span style="font-family: 'Comic Sans MS', cursive;"> ** <span style="font-family: 'Comic Sans MS', cursive;"> I think that it was sort weird because the celery stick turned a bit red at the leaves and that means the system of the celery is taking the water to the leaf. Also it was cool that it turned red because we don't turn red if we drink or eat something red and it is pretty cool that plants could do that

<span style="font-family: 'Comic Sans MS', cursive;"> We noticed that the water had dried out after we took of the lid (this morning) and it stopped flooding

How do the sides and the top of the terrarium look? 11/5/09 Not to dry.

How does the soil look? 11/5/09 Not to dry not to wet and we still have mold from last time

Have any seed sprouted? 11/5/09 Yes

What kind of seed sprouted first? What kind of seed sprouted last? 11/5/09 The corn died and now clover and barely seeds sprouted, and the radish sprouted last

What kind of plant grows best in your terrarium? 11/5/09 Radish and clover

How have the living factors of the environment changed? 11/5/09 The corn died but more seeds sprouted like the barley and clover and the radish.

How have the nonliving factors of the environment changed? 11/5/09 There is mold on the soil.

Which organisms found your terrarium a favorable environment? Why do you think so? 11/5/09 The radish and the clover because they seem to growing green.

How would you recommend planting seeds in a terrarium? How much soil should be on top of the seed? Do different types of seeds require different planting techniques?I would recommend not to put in to much seeds because there won't be any space left, yes

How is the environment in your terrarium different than the more common environment for corn, barley, clover, radishes, and peas? Well we sometimes put in to much water, sometimes to much soil...

If you were going to set up a terrarium again, what would you do differently and why? Water a little less.

What factors might affect the growth of the plants in your terrarium if you repeated the investigation during a different season? we changed to much of the environment at wrong

In a different room in the school? In a different part of the country?

How Much Sugar in our Cereals?

What we did: We chose 2 cereals that we thought might be HIGH and LOW in sugar content. We then added some hot water in a a container keeping the temperature in between 35℃ and 50℃ we then added some yeast with Captain Crunch and Corn flakes

Conclusion

The Conclusion are as suspected that the more sugar there is the more C02 will be created and you could see below what the results are.

Brine Shrimp Hatching
<span style="font-size: 96.8%; font-family: 'Comic Sans MS', cursive;">1. The problem: We wanted to find out... We were trying to find out what type of water (salty, and not salty) could effect the hatching of brine

2. What we did: We tried adding 1-3 spoons in each cup filled with 150 ml of water in each, we then added some brine shrimp eggs and see if it will hatch

3. After 24 hours we noticed... that the brian shrimp in the salted water did not grow or hatch while the brine shrimps in the 1 spoon of salt and the 2 spoon of salt hatched, but the no spoon of salt and the 3 spoon of salt didn't hatch at all.

4. After 48 hours lots of the brine shrimps hatched in cups with salt, the most one now I think is the 3 spoons of salt cup contains the most hatched brine shrimp eggs. Also lots and all of the brine shrimp eggs are sinking in the cup that has no salt, and lots of the brine shrimp eggs are stuck on the edges of the cups, my guess is that the brine shrimp eggs that are sinking and sticking on the side of the cups are dead.

5. I predict that lots of or all of the eggs that are in the cup that has no salt and the eggs that are sticking on the sides of each cup will die.

**How can we find out if the eggs that have not hatched in the cups are still viable? (Alive or able to grow)

Our Plan: 1. Since the brine shrimp in the 0 spoons of cup have not hatched we have decided to add 3 more spoons of salt and see if it grows 2. Also we want to find the 3. 4.**

After 48 hours... 1. Were the eggs in the 0-spoons and 4,5,6 and higher spoon cups viable? 2. Was the hatching robust or did only a few hatch? 3. What advantage is it to the brine shrimp to postpone hatching in salt solutions that are very diluted (little salt) or very concentrated ( much salt). 6. After 60 hours we noticed that lots of brine shrimp in the 0 salt cup died, but more grew in the cups with salt.

Answer

1.
 * The 3 spooned cup hatched only 4 brine shrimp eggs.
 * The 6 spooned cup are still doing fine
 * Same as the 9 spoon cup but this one have some that died
 * Sadly all the brine shrimp in the 12 spoons of sugar cup have all died.

2.
 * Not may eggs hatched, but more died

3.
 * With very little or no salt we think the brine shrimp would not be able to float or hatch, but for cups with more salt some brine shrimp would die but will have a very small life cycle.

My letter to Dr. Bryan

Dear Dr Bryan.

We discovered that brine shrimps would only live in conditions with only a balance of salt, to less salt may cause lots of brine shrimp to sink and die because they won't hatch, from what I know I think that to much salt could also cause lots of brine shrimps to die so we must keep the amount of sugar balanced
