1. Tap water I saw many white things and some very little animal like ants but in water and saw some bubbles. They look like cell. 2. Pond water I saw many white things and some red dots and many bubbles 3. Leaf I saw some water and some breathing hole and grey tiny hole and an animal shape like a worm and tiny red dots.

4. Dead leaf I saw water and many cool white stuff and a grey breathing hole.

Conclusion: Everything seems to be made up of smaller pieces, cells, water, air and maybe other things we.

How do they get food? From the food we eat
 * How do they get water? from the water we take in. Now I know they get food from our blood
 * How do they get rid of waste? the muscle push the waste out. Now I know that the blood carries the waste and send it to the anus.
 * How do they get oxygen? They breath trough there jaws. Now I know they get oxygen from the body of a human.
 * How do human cell get thing to survive? they drink and eat.

 * Once you go inside your mouth or nose you will come through your lungs through a long tunnel in your body
 * There are different blood type like a, b, o, ab
 * You need white blood to survive.
 * Inside the lungs there are sacs.
 * The right side of the heart the blood will come back.
 * The left side of the heart it will send it to the hole body.
 * 2 millon blood cell form every second.

Discussion After Video
 * 1) You heart beat increase its speed.
 * 2) It happen because need more oxygen to the blood cell.
 * 3) They need the oxygen so they can do the work they need to and have to get rid of CO2.
 * 4) Blood platelets form fibrin to block the blood.
 * 5) To much blood escape you will dye and the blood cell won't get there food and die too.
 * 6) The white blood cell because diseases may get in your body and you will die.

1. Why do people eat food? We eat food because if we don't we won't live and we have to feed our cells. 2. What happens to food in the digestive system? In the digestive system food goes down the esophagus and in to the stomach. 3. Describe the path taken by food as it passes through the digestive system. It goes into the mouth and down the esophagus and into the stomach. 4. Explain what happens to food at each place in the digestive system. In the mouth foods turn into sugar and in the esophagus the food goes down into the stomach the food squeezes together. 5. How does digested food get to cells? Once the blood passes by the capillaries near the stomach, the blood exchange the material to get food. 7. Describe how kidneys work. Once the blood passes through the kidneys, the blood gets washed then the waste passes into the urine.

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 heat of water in each vile and put into each vile a celery.
 * Testable question: What kind of water will it survive better in?**

put 20 ml water of cold, normal,warm,and icy water.

**CELERY OBSERVATIONS AFTER 1 DAY BUT //BEFORE// MEASURING 1. What is the general condition of the celery stalks compared to yesterday? It looks dead and very week, it did get water but seem to look unhealthy and it is very hard. 2. How did the water in the vial change from yesterday? Yesterday we put 25 ml water in and now the water seems to be less than yesterday. 3. What do you think happened to the water? I think in a few days the water will be all gone because the plants takes it up and then it evaporates. RED DYE CELERY OBSERVATIONS 1. What did you observe when you first looked at the red-dyed whole celery stalk? I observed that it turned red on its stem. 2. What did you observe when you then looked at the cross section of the celery stalk? <span style="color: rgb(128, 0, 128);">I saw that it had red dots all over it. 3. What do you think the red dots are in the celery stalk cross section? <span style="color: rgb(128, 0, 128);">I think that the red dots are the water vans that water goes to the plants. 4. What is the relationship between the red dots and water in the celery stalk? <span style="color: rgb(128, 0, 128);">The relationship between the red dots and water are that we put red in the water so it turned red. ****MY CONCLUSIONS FOR CELERY EXPERIMENT B:

** Making Food-Article

**PHOTOSYNTHESIS This is the equation:
 * The form of food produced in plants is sugar. The process that makes sugar is called** PHOTOSYNTHESIS**.** PHOTOSYNTHESIS **happens in green cells.

Cellular Respiration**
 * 1) People eat food so they can feed there cells.
 * 2) The cells get energy from food because the food they eat turns in to sugar.
 * 3) The plants get food from the sunlight and the water because they turn into sugar cerellas.
 * 4) during the cellular respiration the body break apart the sugar into little pieces.

**How Much Sugar in our Cereals?

What we did: We chose 2 cereals that we thought might be HIGH and LOW in sugar content. Then we put yeast in the 2 bag and weight the cereals to see if they weight 3 grams. Next we put in hot water between 35 - 50. Third we put in in the bath for ten minute and then we put it in the cylinder and check how many oxygen is in there and know we did it with 20 minutes.

solar energy must be present with the 6 molecules of carbon dioxide and the 12 molecules of water in order for PHOTOSYNTHESIS (or the making of sugar) to occur.

Photosynthesis:
 * 1) Sugar is carbon dioxide, water, and light that combine together to make sugar for cells
 * 2) The raw materials needed by plants are carbon, hydrogen, oxygen.
 * 3) Chlorophyll is contained by light absorbed by molecules.
 * 4) Photosynthesis is the process by which green plants make sugar from carbon dioxide and water in the presence of light.
 * 5) Plants produce food from the carbon dioxide, water, and light.
 * 6) It stared as carbon dioxide, water and sunlight.

We found out that the sugar is food for the yeast and not the flower because every living thing need sugar so they can feed there cells so they can survive.

What we did:
 * 2. ** ** My Terrestrial Environments Journal **


 * First we added 250 ml in the tank
 * We covered the tank with a foil.
 * Next we took some water out we took 60 ml.
 * Then we add 260 ml to it.
 * Then we added the lid.
 * Then we took out the lid and the plastic cover out.
 * We had some mole, so we took it out.
 * We took the lid out
 * We gave the plants 250 ml water.

**Brine Shrimp Hatching** 1. The problem: We wanted to find out if the salinity will have an effect on the Brine Shrimps.

2. What we did: We used a special kin of water and a few spoon of salt to find if the senility will have an effect on the Brine Shrimp.

3. After 24 hours we noticed that the Brine Shrimp has hatched and that they are very small.

4. After 48 hours we noticed that number three know has the most and not number 2 any more.

5. I predict that the 0 salt spoon will never hatch because it doesn't have any salt and it needs salt to survive. The 1 salt spoon I also think that it will not survive because it doesn't have enough salt to eat and drink. The 2 salt spoon I think that is is a good amount of salt but I think that they won't all hatch. The 3 salt spoon is the best because they almost all hatched but some of them are stuck on the cup.

6. After 60 hours we noticed that there are almost no Brine Shrimp in all of the cups just 1-10 of them in cup 2 and none in 0, 1, and 3.

My Letter to Dr. Bryans:

Dear Dr. Bryans

None of our Brine Shrimp in 0 spoon of salt are alive and also never hatch and in the 1 spoon of salt very little of the shrimp hatch and we wonder why? Maybe because it ran out of salt because salt is the food for the shrimp. Then in 2 spoon of salt the Brine Shrimp hatch the most and on 3 spoon of salt it didn't hatch on the second day it also didn't hatch but on the 3rd day it hatch a lot.


 * Why did the 3 spoon of salt hatched last?


 * Why did the 1 spoon of salt hatch and died less than 24 hours?


 * Why did the Brine Shrimp died when it ran out of salt? If we close the lid it wouldn't run out so it should not die but our did.

From Mercedes

**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. We change our volume from 0,1,2,and,3 spoon of salt to 4,5,6,and 7 spoons of salt. 2. Next we are going to look and see how many had hatched and compare it to our first experiment. 3. Then we will wait for another day and do the same thing. 4.** Last we will see if the brine shrimp will survive for a long time with a lot of salt or if it does not and also when it will hatch.

After 48 hours... 1. Were the eggs in the 0-spoons and 4,5,6 and higher spoon no it was not robus.cups viable? Yes, one was viable. Number 7 because we saw a lot of Shrimp moving and so we Know that they are alive. 2. Was the hatching robust or did only a few hatch? No it was not robust 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).

 * Notes on video "Plant Structure and Growth":**

1. What is classification? <span style="color: rgb(128, 0, 128);"> Classification is a group of things that fit in one category. Also means to identify what shape, hight, or length they are in. And sorting things out in to classes of group. (Scientist do this all the time.) 2. What are three different ways you can classify leaves? the first way you can classify leaves are by parallel. <span style="color: rgb(128, 0, 128);"> The second way you can classify leaves are by pinnate. The third way you can classify leaves are by palmate. 3. If you had a collection of insect, what ways might you classify them?**

Glossary
cross section - is a cut across and object and exposes its internal structure. Cell - Is the basic unit of life! Oxygen - Is an atmospheric gas (in the air) needs to support life. Carton Dioxide - Waste gas produced by all living things. Pulse - The result of the blood being pushed through the blood vessels by the beating of the heart. Heart - The organs that pumps the deoxygenated blood around the body. Blood vessels - The arteries and veins and capillaries that carry the blood around the body. Blood - Is a liquid that flows to and from the cell in the blood vessels. The humans heart has four chambers - right ventricle, left atrium, and left ventricle. The circulatory system - includes tissues (blood and blood vessels) and organs (heart) that transport life-support substances to cells AND remove waste! The respiratory system-includes the tissues and organs ( lungs) that provide gas exchange ( o2 and CO2) between the blood and atmosphere. Vascular plant - a multicellular plant that has vessels for transporting water, minerals, and sugar to all its cell. Xylem- found in vascular plants. Tubes to transport water and minerals to cells. Phloem - found in vascular plants. Tubes in transport sugar to cells. Sap - the sugar rich liquid flowing in the phloem. classify - sorting things out in to classes of group (scientist do this all the time) Pinnate, parallel ,and palmate are the way vascular plants insist three ways vascular plants can be classifly stomata - is something similar to stomach. food-Is the source of energy and building materials for living cells Photosynthesis- is a chemicals process in which cells produce energy-rich sugar molecules and release oxygen. Fat and protein-are groups of nutrients that provide energy and building blocks for growth and development. mass-is a quantity of mass. sunlight-is solar energy. Light from the sun. starches-are chemicals produced by plants to store food. molecule-is a particle made of two or more atoms. A sugar molecule is made of carbon, Hydrogen, and oxygen atoms. Yeast is a single cell organism. cellular respiration is the process by which plants and animals cells break down sugar to get energy, releasing carbon dioxide in the process.

Blood flowing through the circulatory system delivers nutrients and removes waste 3. It collects blood from the lungs 14/3/09 Ms 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.
