Science+Thinking

= SCIENCE JOURNAL SETUP= =1. My Living Systems Journal  =

1. Create a title page that says: My Living Systems Journal with your name 2. Create a contents page that says: Contents, then page 1, 2, 3, 4, etc. on each new line, then add the titles of the pages as you make a new page. 3. Pictures of Amoebas for you to use:

4. Look for more pictures to use in your journal on 'Hahn share' on the server as they are made. e.g. the leaves under the microscope! Internet also - OR YOUR OWN PHOTOS! 5. Add your new pages with numbers on them. Then add them to your Contents page 6. Create a Glossary page to add new words and definitions 7. Copy this for your Digestive System and Excretory System review page:

THE DISASSEMBLY LINE REVIEW
1. Why do people eat food? 2. What happens to food in the digestive system? 3. Describe the path taken by food as it passes through the digestive system. 4. Explain what happens to food at each place in the digestive system. 5. How does digested food get to cells? 6. Why do people need kidneys? 7. Describe how kidneys work.

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:
 * Testable question:**

Copy this: **


 * Celery Condition || Starting volume of water (mL) || Ending volume of water (mL) || Starting mass of celery (g) || Ending mass of celery (g) ||

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? 2. How did the water in the vial change from yesterday? 3. What do you think happened to the water?

RED DYE CELERY OBSERVATIONS 1. What did you observe when you first looked at the red-dyed whole celery stalk? 2. What did you observe when you then looked at the cross section of the celery stalk? 3. What do you think the red dots are in the celery stalk cross section? 4. What is the relationship between the red dots and water in the celery stalk? ****MY CONCLUSIONS FOR CELERY EXPERIMENT B:**


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

1. Describe how all the cells in a vascular plant gets sugar. 2. Describe how all the cells in a vascular plant get water. 3. Why do the leaves turn pink when a celery stalk is placed in red dye? 4. In what ways are blood and sap the same? ** ** Making Food-Article
 * Vascular Plants Thinking:

****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.
 * Solar energy must also be presen**t 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 .... 2. The raw materials needed by plants.... 3. Chlorophyll is ....... 4. 5. 6.

Cellular Respiration

1. 2. 3.

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....



GLOSSARY

Yeast is a single-celled organism. **Cellular respiration **is the process by which plants and animal cells break down sugar to get energy, releasing carbon dioxide in the process.**

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

Terrarium observations 11/5/09: **


 * We noticed...

**Questions to consider:** · How do the sides and the top of the terrarium look? 11/5/09 · How does the soil look? · Have any seeds sprouted? · What kind of seeds sprouted first? What kind of seed sprouted last? · What kind of plant grows best in your terrarium? · How have the living factors of the environment changed? · How have the nonliving factors of the environment changed? · Which organisms found your terrarium a favorable environment? Why do you think so? · 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? · How is the environment in your terrarium different than the more common environment for corn, barley, clover, radishes, and peas? · If you were going to set up a terrarium again, what would you do differently and why? · What factors might affect the growth of the plants in your terrarium if you repeated the investigation during a different season? In a different room in the school? In a different part of the country?

**Brine Shrimp Hatching** 1. The problem: We wanted to find out...

2. What we did: We used... to...

3. After 24 hours we noticed....

4. After 48 hours we noticed....

5. I predict that... 6. After 60 hours we noticed...

**My Letter to Dr Bryans:**

Dear Dr Bryans,

From,

**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. 2. 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).
