Ms Hahn's corrections for you: 1. 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.

 * To supplies your blood cells with more oxygen.
 * It helps to them, because they needs oxygen to keep them active.
 * They have to get rid of the CO2, because it is toxic.
 * The blood platelet form the fibrin the make scabs to stop blood going through your cuts.
 * The blood helps, because if you loose to much blood then your cells will die then you will die.

**CELERY EXPERIMENT A**
Design an experiment to get information about rootless celery and water. The materials available to you include: 2 Stalks of celery with leaves 2 Stalks of celery without leaves 4 Vials
 * Experimental Design**

1 vial holder

measurement tools While you work on your experimental design, think about these three things. • Leaves might affect how celery interacts with water. • The mass of the celery might change. • The volume of water in the vial might change. Plan to answer our question: Try different tempreture of water in each vile and in a celery. **
 * Testable question: What kind of water will it survive better in?
 * 1) Put different ml of cold, normal and icy water.
 * 2) Put a celery into each vile and put the leaf in there.


 * Celery Condition || Starting volume of water (mL) || Ending volume of water (mL) || Starting mass of celery (g) || Ending mass of celery (g) ||
 * Leaf 1 || 25 ml || 21 ml || 52 grams || 35 grams ||  ||   ||
 * Leaf 2 || 25 ml || 16 ml || 13 grams || 18 grams ||  ||
 * Leaf 3 || 25 ml || 20.5 ml || 41 grams || 20 grams ||  ||

Copy these 3 reflections on the celery experiments and answer the questions as far as you understand today:

**CELERY OBSERVATIONS AFTER 1 DAY BUT //BEFORE// MEASURING 1. What is the general condition of the celery stalks compared to yesterday? <span style="font-size: 110%; color: rgb(142, 5, 209);">It looks dead and tired even though it had water it still. 2. How did the water in the vial change from yesterday? <span style="color: rgb(142, 5, 209); font-size: 110%;">The water has gone down a lot and it looks dirtier. 3. What do you think happened to the water?<span style="color: rgb(142, 5, 209);"> I think the water was sucked into the plant so it could live longer. RED DYE CELERY OBSERVATIONS 1. What did you observe when you first looked at the red-dyed whole celery stalk? <span style="color: rgb(128, 0, 128);">I see that the celery looks red and when it's in normal water it looks healthier. 2. What did you observe when you then looked at the cross section of the celery stalk?<span style="color: rgb(128, 0, 128);"> It has red dots that go all the way to the top of the plant. 3. What do you think the red dots are in the celery stalk cross section? <span style="font-size: 70%; color: rgb(128, 0, 128);">The red dots go across the xylem and the xylem carries it up to the top. 4. What is the relationship between the red dots and water in the celery stalk? <span style="color: rgb(128, 0, 128); font-size: 70%;">Since the water was red the xylem carries it up to the top and the plant absorb the water. ** <span style="background-color: rgb(255, 0, 255); font-size: 20px; line-height: 29px;">**<span style="background-color: rgb(255, 255, 255);">MY CONCLUSIONS FOR CELERY EXPERIMENT B: ** 1.

What do all plants have in common?

a) They're all vascular. b) They all perspire c) They all in soil <span style="background-color: rgb(255, 255, 0);">d) None of the above

What does the stem do?

<span style="background-color: rgb(255, 255, 0);">a) of the below b) Connects the roots to the leaves. c) Helps the plant stand up tall so it can reach for the sun

In which part of the leaf does photosynthesis occur?

a) The stomata b)It doesn't occur in the leaf at all. It happens in the roots. <span style="background-color: rgb(255, 255, 255);">c) The mesophyll

What do all plants have in common? Rigged cells walls + Chlorophyll + tissues + organs

What are two types of the vascular plants tissues? The xylem - water - nutrients - to the leaves + the phloem - sugar - To wear ever it is needed.

How are the trunk of the tree and the stem of a flower the same? They both have vascular bundles.

What does the ring of a tree represent? Every year the ring of a tree adds more and more and the old one are in the middle and the new ones are on the out side.

When you look at a tree trunk why is is it wide and thin? The wetter the year is the wider the ring is and the dryer the year is the smaller the ring is.

How is the vascular system similar to a circulatory system in the human body? The nutrients, sugar, waste disposal, Co2, oxygen.

PHOTOSYNTHESIS This is the equation:** Solar energy must be present with the six molecules of carbon dioxide and the 12 molecules of water order for PHOTOSYNTHESIS (or making of sugar) to occur. My cells only process in sugar to occur.
 * The form of food produced in plants is sugar. The process that makes sugar is called** PHOTOSYNTHESIS**.** PHOTOSYNTHESIS **happens in green cells.


 * 1) Sugar is a source of nutrients and food to feed the cells in plants, animals, humans and other living creatures. You could get sugar for your cells by the food you eat.
 * 2) The raw materials needed by plants are Carbon dioxide, water and light and when it combined it makes sugar.
 * 3) Chlorophyll is cells that takes light and it observes the energy.
 * 4) Products of photosynthesis are sugar, oxygen, water and light, they go to the leaves.
 * 5) they produce the food in their leaves.
 * 6) It stared as carbon dioxide, water, and sunlight

Yeast:

When we put sugar, cookies and warm water with yeast it activates the yeast better than doing the same thing, but have flour instead of sugar. When you put the flour the yeast doesn't really activate. When yeast and cells get sugar it eats it and survives and make energy and also make the yeast produce.

 * 1) People eat food, because we need energy to live and because we're hungry.
 * 2) It takes the sugar and breaks it down to little pieces.
 * 3) they get the food they need from the sunlight, water, sugar and CO2.
 * 4) The cellular respiration breaks the sugar down for the cells.

How much Sugar in our Cereals

<span style="font-family: 'Comic Sans MS', cursive; color: rgb(128, 128, 128); font-size: 110%;"> What we did:

We chose 2 types of cereals that we thought might be HIGH and LOW in sugar content. Then we labeled the high and low bags after that we put 100 ml in the high and low bag. We got hot water from 35 to 50c then after that we make sure it 50 ml and put it in both bags. We put the thermometer in to cheek the temperature and the wet put it into the bath. After 10 minutes we take them out and we measure it and do it again for 20 minutes now.

Sugar Control 50ml 50ml
 * Food Tested || Amount of CO2 in 10 min || Amount of CO2 in 20 min ||
 * Koko Krunch || 100ml || 200ml ||
 * Corn Flakes || 0ml || 0ml ||
 * Cornflakes || 50ml || 100ml ||
 * Captain Church 100ml 230ml ||  ||   ||
 * Choco Bits || 100ml || 0ml ||
 * Cornflakes || 50ml || 0ml ||
 * Cookie Crisp || 150ml || 150ml ||
 * Frosties || 100ml || 150ml ||
 * Corn Crunch || 150ml || 150ml ||
 * Cheerros || 50ml || 50ml ||

Most of the cereals gained less ml. I think this because most of the cereals gained less ml of CO2.

**Vascular Plants Thinking: 1. Describe how all the cells in a vascular plant gets sugar.<span style="color: rgb(128, 0, 128);"> The phloem takes the sugar from the leaves. After that it transport the sugar to sap. Then the phloem transport the sugar to every living cell. It is liquid sugar though. 2. Describe how all the cells in a vascular plant get water.<span style="color: rgb(128, 0, 128);"> The xylem takes the water for the cells in the ground and up to the leaves. The tubes transport the water and minerals to the cells. If the cells didn't get the water it will die. 3. Why do the leaves turn pink when a celery stalk is placed in red dye. <span style="color: rgb(128, 0, 128);">Because the xylem take the water. Then the plant absorb it, but xylem goes against gravity so the red water goes up to the leaves. 4.

1. The problem: We were trying to find out how many spoons of salt would work best for the brine shrimp to survive in. And how the salinity of the water would have an effect on the shrimp.

2. What we did: We used 0 1 2 3 spoons of salt into different cups and we put 150ml of water also we put one minispoons of brine shrimp in to the cup and swirled the cup and left the brine shrimp to hatch.

3. After 24 hours we notice that some of the shrimp has hatched and started to move. They look like jelly fishes.

4. After 48 hours some of of the shrimps died and there's a little bit more in the 3 spoon of salt. One the cup with 3 spoons of salt barely any of the brine shrimp hatch. On the one with 2 spoons of salt has load of hatched brine shrimp in it. On the one with 1 spoon of salt only a few has hatch but no all. One the of with 0 spoons of salt all the eggs are getting suck to each other and sinking.

5. I predict that:

Most will survive but none of the 0 spoons of salt will survive they will all die. I predict more eggs will hatch and grown into it normal size like number 1 2 3 spoons of salt.

6. After 60 hours we notice that The brine shrimp in the 0 spoons of salt has all died and it is like a big graves yard. The brine shrimp in the 1 spoon is mostly dying and there is only a few left. The brine shrimp in the 2 spoon of salt has an extreme chance of dying. The brine shrimp in the 3 spoons of salt has a few shrimps left.

**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 only the cup with 2 and 3 spoons of salt had brine shrimp that hatch in it we knew i was a high number so we did 4,5,6 and 7 50 ml spoons of in each cup for the brine shrimp. 2. We are going to observe the brine shrimp on the 2/6/09 and we are using the magnify glass to see if any brine shrimp grew in it. 3. We will check it everyday and see how much did the shrimp increase. 4.We will see most and less.**

<span style="font-size: 110%; font-family: 'Comic Sans MS', cursive; color: rgb(0, 128, 128);"> After 48 hours we checked our cup to see if any brine shrimp has grown and so has grown in different cups. <span style="font-size: 110%; font-family: 'Comic Sans MS', cursive; color: rgb(0, 0, 0);">

1. Were the eggs in the 0-spoons and 4,5,6 and higher spoon cups viable?

Yes some were viable, because it living healthily in the cup.

2. Was the hatching robust or did only a few hatch?

No it was not robust and only a few of them hatched.

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).

Yes it did have an effect for the brine shrimp growing when you add more salt and less salt in the cup.

My Letter to Dr. Bryans:

Dear Dr. Bryans, our experiment on the brine shrimps are successful. I have learned that.
