The purpose of this experiment was to see if either caffeinated or decaffeinated coffee affected a plant’s overall health. Its health is determined by the plat’s height over the course of thirty days, the plants’’ mass on the thirtieth day, and its chlorophyll a and chlorophyll b concentration. The majority of the world has become acquainted with the well known stimulant caffeine. Not much is known about any effect caffeinated or decaffeinated coffee may have on plants The fast plants were…

Normal standards for specific gravity are as typically as follows: 1.000 to 1.030 is a normal specific gravity, 1.001 after drinking excessive amounts of water, more than 1.030 after not drinking very many fluids and concentrated after receiving an antidiuretic hormone (ADH). Max’s urine concentration varied in concentration each time he was tested. The first test showed that his urine was a pale yellow which was an indication that he was hydrated. The second test showed the concentration to be…

made up of two sections; the first section measures the density of water and the density of an unknown substance. If the procedure is performed correctly, the actual density of water will equal the theoretical density of water. In the second section, the density of an aluminum sample will be measured and afterwards compared to the accepted density of aluminum and an unknown sample…

capacity, mixed with 20ml. of carbon tetrachloride, 30ml of glacial acetic acid and finally 1ml. of saturated potassium iodide solution. After well shaken for 1minute, 100ml. of distilled water was added to and thus free iodine liberated in the solution was titrated by 0.01N thiosulphate solution. 1 ml. of this. thiosulphate solution corresponds to 0.00008g. of oxygen. The acid ester used here was prepared from cuttle fish oil as described…

After we gathered our materials we measured 23 g of sodium nitrate and 200 mL of water. After measuring the water we put the water in the small bag. Then we took the initial temperature of the water, which was 23 degree celsius. Then, we put the 23g of sodium nitrate into the big bag. After that we put the small bag(unsealed) into the big bag(sealed). Then, we mixed the two substances together…

My experience with Holz Lake was unique to say the least, from leaking waders to completely falling into the water it was all a very hands on activity. Coming to SES one of the things I was most excited for was the pond profile. All of the teachers said, “Don’t feel bad if you fall into the pond, it happens every year.” Hearing this, I knew I would likely be the student to fall into the pond. I’m just that clumsy; however I planned to be very cautious during every visit to the pond. Our…

you had made up my mind. As you waded into the warm azure water, you began to worry. “What if a shark comes” “are my family still in the boat?” you pushed these worries out of your mind and dove in. the water was warm, and that was a good thing, there was a cold wind standing on the beach. The boat was about a hundred feet out in somewhat deep water, maybe 20 feet. Around the boat there was an oil slick “I’ll have to dive under that” you though as you approached. Suddenly, a great shadow loomed…

able to survive and live comfortably in. Temperature was found to be a factor affecting the rate of oxygen consumption by altering dissolved oxygen levels. As stated by Powell et al. (2006), there shows to be less dissolved oxygen in warmer waters, and these waters have been found to increase rates of ectotherms that are in the respective conditions, because in order to survive they must acclimate to their environment (Daniels and Ermitage, 1968). According to this study, if the crayfish used…
