 * Does adding salt to a plant's water affect its health? How much salt can a plant tolerate before it dies?

Tim, can we think of another idea. The result is obvious. Plants cannot adapt to salt water.


 * TOPIC: Chemistry Colors**

=﻿I Problem:= Sometimes when scientists do an experiment, such as a chemical reaction, they may be very interested in the colors produced during the reaction. Scientists may need to observe the color very closely to compare it with another color. Using powers of observation to try to create an exact color match using a chemical reaction.

=﻿II Materials:=
 * Alka-Seltzer
 * Three clear plastic bags
 * Red cabbage
 * Lemon juice
 * Baking soda
 * Small cups (for lemon juice and baking soda)
 * Straw
 * Flat toothpick
 * Zip-closing plastic bag
 * Water
 * Masking tape
 * Paper
 * Pencil

=﻿III. Procedure:= > See if you can add the right amounts of lemon juice and baking soda to the indicator in cup B to produce the exact color that the five drops of Alka-Seltzer solution produced in cup A. Add one drop of lemon juice to the indicator solution in cup B. Swirl the cup. If this does not match the color of the solution in cup A, use your toothpick to add a small amount of baking soda to cup B and swirl again. Keep track of the exact amounts of lemon juice by drops and baking soda by toothpicks you are adding. Observe the colors in the two cups very closely. =﻿IV. Hypothesis: My hypothesis is that, I will be able to produce identical colors through two different chemical reactions.= =﻿V. Data=
 * 1) Tear up two or three red cabbage leaves into small pieces. Place the pieces into a zip-closing plastic bag. Add one cup of warm water to the bag and seal it tightly.
 * 2) Squeeze the leaves in the bag until the water turns a dark blue color. This is your indicator solution. An indicator can change color when certain substances are added to it. Use masking tape and a pencil to label two of your cups A and B. Pour 1/4 cup of the indicator into each of the two cups.
 * 3) In a separate cup, add 1/4 cup of water. Place one Alka-Seltzer tablet in the water. Wait for the tablet to dissolve completely. Use your straw to place five drops of Alka-Seltzer solution into cup A. Swirl the cup. What do you see? How does the color in cup A compare with the color is cup B?
 * 4) Look at the ingredients on the package of Alka-Seltzer. Aside from aspirin, the ingredients are sodium bicarbonate and citric acid. Sodium bicarbonate is baking soda, and citric acid is the acid in citrus fruits such as lemons and oranges.
 * 1) When you think you know the right amounts of lemon juice and baking soda, rinse out cups A and B to get ready to test your results. Place 1/4 cup of indicator in cups A and B. Add five drops of Alka-Seltzer solution to cup A as before, and swirl. All at once, add the exact amount of lemon juice and baking soda that you think will match the color in cup A, and swirl.

=﻿VI. Conclusion=

=﻿Journal:= I finally picked my project. I will get my materials soon, then i will begin my project. **3-30-11**
 * Journal:**
 * Getting my materials today, and starting soon. 4-12-11**
 * Journal:**
 * Today, i wa splanning out, how I wanted to put my project together and how**
 * I would want it to look. 4-19-11**
 * journal:**
 * have my materials, just getting ready to get my board. 4-21-11**

=﻿Journal Date= I wrote my rough draft of my abstract report, 4-22-11 =﻿Journal Date= Today, I am working on putting my bscience board all to gether. Also I am finishing the final copies of my writing parts of my project. 5-8-11 =﻿Journal Date= i am finishing my abstract paper, and today, i got my pictures for my project. 5-9-11
