Can you come back to us? Jen, Lenora, Linzi, and Alison

We all......... -we have all been to the beach -we all have beds -we are all happy :) -we all are girlssss !! :D  -we are all awesome  -we all love ice cream  -we all own a pair of jeans  -we all like to stalk people(only on weekends!)Linzi doesn't stalk people!! ... Jen just.. yeah.  **6/8 Egg Drop Lab:**

5/11 Alka Seltzer Lab:
Question: How will the mass of the reactants compare to the mass of the products when a gas is formed? Hypothesis: The mass of the products will be less than that of the reactants when the gas is released. IV: Mass of the reactants (grams) DV: Mass of the products (grams) Constants: The amount of water, the time you put the lid on when the lid is taken off Procedure: AVERAGE DIFFERENCE: 3.15 grams
 * 1) Measure the mass of the brown cylinder and cap.
 * 2) Measure the mass of the alka seltzer and water with the brown cyclinder and cap, without letting the alka seltzer and water react.
 * 3) Flip the alka seltzer into the jar with the cap and secure the lid.
 * 4) Measure the mass while the cap is still on, and note any changes.
 * 5) Remove cap, releasing gas, and measure the mass again.
 * 6) Record results and note any changes in mass.
 * 7) Complete 2 more trials.

5/10 Lab:
Question: How will the mass of the reactants compare to the mass of the products in a reaction that produces a solid precipitate? H: We think the mass of the products and reactants must be the same before and after the reaction according to the law of conservation of mass. IV: Mass of the reactants (grams) DV: Mass of the products (grams) Constants: Same balance, mass of the glassware Procedure: OBSERVATIONS:
 * 1) Find the mass of the glassware.
 * 2) Add some sodium iodide to test tube A.
 * 3) Add some lead nitrate to test tube B.
 * 4) Record new masses. (glass and chemicals)
 * 5) Pick up the 2 test tubes and flip them upside down in the beaker.
 * 6) Record the new mass. Subtract the glassware from the new mass to find the chemicals' mass.
 * 7) Dump the chemicals into the funnel.
 * 8) Do a second trial, and then a third trial, after cleaning the glassware thoroughly.
 * 9) <span style="color: #800080; font-family: 'Comic Sans MS',cursive;">Record observations.
 * <span style="color: #800080; font-family: 'Comic Sans MS',cursive;">1st trial: When the chemicals were dumped into the beaker together, they instantly changed to a bright, dark yellow.
 * <span style="color: #800080; font-family: 'Comic Sans MS',cursive;">2nd trial: Observations were very closely related to those of trial 1.
 * <span style="color: #800080; font-family: 'Comic Sans MS',cursive;">3rd trial: Observations were the same as the first and second trial.

Sodium bicarbonate & water: The sodium bicarbonate dissolved in the water. **In the experiments the temperature lowered after the substance was added, except for the calcium chloride and water because the temperature raised almost 6 degrees. Bromothmyl blue & Calcium Chloride: When mixed it turned a light blue. The temperature increased as it was mixed together. Calcium Chloride & Sodium bicarbonate: Temperature raised when mixed. The mixture fizzed up for a few seconds almost like when you open a soda.

Concentration Lab!!! 4-12-11 Here is our lab:

Question= How doex mixing effect concentration?

Hypothesis= We think faster mixing will make the solution more concentrated.

Independent Variable= The solute and solvent

Depentdent Variable= The type of mixing process

Constants= Amount of water, amount of kool-aid, time spent mixing

Procedure=

1. Put 2g of kool-aid in 10mL of H2O in 4 2. Flick mix the 1st one for 30 seconds 3. Flip mix the 2nd for 30 seconds 4. Shake for 30 seconds 5. Leave the last one alone to dissolve by itself.

The concentration for each test tube was 1 g/5 mL! To find it, we put the 2g over 10mL, then simplified to get our final answer. We mixed it by flicking it, flipping it, and shaking it. --> The "Hick mix" in the table is supposed to be Flick mix, but Alison messed up. :)

Watch our solubility vocab video! 4-11-11 :) []  feature=mhum#p/u/0/nWt-B1BiwQM  The link is messed up, so just copy it and paste it into the search  bar. Here are our materials!!! 1. Copper II Sulfate 5. Graduated Cylinder  2. Zinc Oxide 6. Test Tubes(4)  3. Lab Glasses 7. Test Tube Rack  4. Lab Scoop 8. Test Tube Stopper  9. Water

Solubility Lab 4-7-11 Heres what we did....... 1. First we added copper II sulfate to 5 mL of water. 2. Then we added copper II sulfate to 10 mL of water. 3. Next, we added zinc oxide to 5 mL of water. 4. Then we added zinc oxide to 10 mL of water. 5. Lastly, we mixed all of the substances by placing a stopper on top of the test tube and turning it back and forth.

Solubility Lab Set Up 4-6-11 Plan for lab tomorrow: 1. Put zinc oxide in 5 mL of water. 2. Put zinc oxide in 10 mL of water. 3. Put copper sulfate in 5 mL of water. 4. Put copper sulfate in 10 mL of water. 5. OBSERVE!! Research!!!! Zinc oxide: []
 * non-toxic
 * It is an additive in many products such as plastics, ceramics, glass, etc.
 * It is very popular in medicine, such as in ointments!!

Copper II Sulfate: []
 * CuSO4
 * Can be harmful if inhaled or ingested
 * It is safe to work around if you are wearing safety glasses and have the proper ventilati
