This led to an experiment which you can try for yourself and investigate the amount of carbon dioxide dissolved in different beverages and how much can be released at different temperatures. To do this experiment I used a few 16 ounce (454 milliliter) plastic bottles of Pepsi One (at room temperature) and an electronic scale that could hold 0.5 Kg and could be tared.Your chemistry teacher may have such a scale. First I put a bottle of the Pepsi One on the scale and pressed the "tare" button. This sets a 'zero' on the scale so that
elab Information Purpose Explore the law of independent assortment by examining a dihybrid cross in mice. Time Approximately 45 minutes Question What is the effect of the inheritance of one trait on the inheritance of a second trait? Hypothesis If a mouse inherits a particular form of one trait, then the inheritance of the other trait will not be affected because alleles assort independently. Summary You will study two traits of mice: fur color and eye color. Throughout the lab: • B represents the dominant allele for fur color (black fur).
Ocean County College Department of Chemistry [Observations of Chemical Changes] Submitted by Andrew Grimm Date Submitted: 5/31/14 Date Performed: 5/31/14 Lab Section: Chem-181DL2 Course Instructor: Amal Bassa Purpose The main goal in this experiment is to observe the properties of simple chemical reactions, and relating their chemical properties to household products. Procedure To begin this experiment I placed two drops of NaHCO3 into well A1 of the 96-well plate, and then added two drops of HCl into well A1. Next I placed two drops of HCl into well B2, and added two drops of BTB, and observed the color. Then I placed two drops of NH3 into well C1 and added one drop of BTB, and observed the color. Next I added two drops of HCl into well D1, and then added two drops of blue dye, and recorded what I saw.

After extraction was performed on the tablet it was then ran through an HPLC test. After performing HPLC and using the line equation three concentrations were found as well as the three main ingredients. The three main ingredients were caffeine, aspirin, and acetaminophen. The final concentrations were 0.02 mg/mL, 0.06 mg/mL, and 0.21 mg/mL. It

Reduced air pressure; behavioral tests; strain of the rat b. Body weight; climbing ability; time of day c. Atmospheric pressure; age of rat; climbing ability d. Number of decompressions; body weight; home cage e. Experimental group; control group; test performance 4.
Testable Question: What will happen if you put one package of mentos into water, vinegar, or diet coke respectively? Initial Observation and Research: Water, vinegar, and diet coke are different in their composition. Hypothesis: One package of mentos + regular water = no reaction One package of mentos + vinegar = some bubble created One package of mentos + diet coke = an eruption is created with lots of mentos Material and Supply: 1L of water, 1.5 L of vinegar, 2L of diet coke, some stick, 3 packages of mentos, some business cards, some regular paper Procedures: 1. A tube was made by rolling a piece of paper and stick. 2.
Mrs. Frisby and the Rats of NIMH created a strong feeling on individuals. Most likely because individuals considered that someplace in this world mice and rats might actually be up amazing like this. Having re-read it as an adult, individuals observe currently that sensible and unsentimental style of writing of Robert C O'Brien creates it all appear probable (Charlotte, 1998). Although they recognized the conclusion, they still discovered themselves drawn into the story from begin to end and entirely won over through the rodents of the title. Mrs. Frisby, a mouse, is attempting to watch out of her children on her individual since her husband was eaten through the cat of farmer, Dragon.

In his book, Mr. Earleywine presents an entire chapter devoted to how smoking marijuana impacts thought, memory, and just the mind in general. Earleywine lists the acute effects of smoking marijuana and what functions of the mind are likely affected or unaffected as a result. Earleywine then goes into great detail about each of the listed functions of the mind and how marijuana does or does not affect each particular function. Earleywine also presents studies done using over each of the effects, and then draws conclusions based on all he wrote about. Finally, he presents some studies supporting a different viewpoint: marijuana smokers might have an advantage over non-users.
