Crayfish are freshwater crustaceans that use their claws called chelipeds,for warning off predators. When frightened, these crayfish lift their chelipeds to make threatening gestures, all while moving backwards or staying still. We examined how long it would take for crayfish to calm down once removed from the water and if the temperature had any influence to this observation. To do this, we placed two crayfishes in room temperature water and another two in colder water for an interval of five…

pressure) and degrees Celsius (for temperature). Flask placed and entirely covered in ice-water bath. Readings stabilized and stored. Ice-water bath is dumped. Beaker filled with cold tap water. Readings taken again. Used temperature probe to measure hot-water bath. Used beaker tongs to remove beaker from the hot plate between 50 and 60 degrees Celsius. Readings taken again. Used beaker tongs to place beaker back on hot plate and heated between 80 and 90 degrees Celsius. Flask placed into…

The Effect of Cellular Respiration at Low and High Temperatures Introduction Cellular respiration can include two processes, aerobic respiration and anaerobic respiration. The main purpose of cellular respiration is to breakdown sugars into smaller structures so that the cell can use it as energy (Reece, et al. 2014). The main concept of the respiration lab is aerobic respiration. This is the process that organic compounds will be degraded from oxygen to produce water, carbon dioxides, and…

compounds by chemical oxidation. In this lab we compared the change of the consumption of oxygen in germinating peas as it underwent changes in temperatures of either ten degrees Celsius, or 22 degrees Celsius (room temp.) to the oxygen consumption of dried peas as it also underwent the same temperatures of ten and 22 degrees Celsius. I hypothesized that the germinating peas would consume more oxygen than the dormant/dry peas at the 22 degree temperature rather than at the ten degree temperature…

After doing some research, I looked at a number of issues effecting the environment which are caused by humanity in its relations with the earth and life on it. There were discussions conducted and utilized readings which were assigned to different topics involving the environment. The main focus evolved around climate change; the causes and possible outcomes. However there are more problems on determining the ethics of our solutions than actual solutions. What are we doing to protect the…

The final oven temperature must be at least 100 degrees celsius. Teams are allowed to purchase additional supplies for their oven, but will had to their cost. The maximum dollar value a team can spend on additional material is $20. However, teams are not permitted to purchase focusing lenses. Also, teams are not…

It was identified as more alka seltzer is broken it is dissolved faster. The experiment was to put alka seltzers that is broken into ½, ¼ and unbroken ones into 125ml, 21 degrees Celsius (room temperature) water. The trend occurred because the decrease of the size of the particles which increase the rate of reaction because the surface area of reactant (alka seltzer) has been increased. A larger surface area has increasing target…

Fahrenheit, commonly known as a unit of measurement for temperature which is regarded as an official scale in the modern society of the United States and other Caribbean countries. It is the first standardised temperatures scale which was adopted globally in the seventeenth century. This great invention is named after a German science instrument maker, Gabriel Fahrenheit (1686- 1736). His invention has revolutionised the design of thermometer in 1724 when he conducted the first mercury…

Delray Beach residents enjoy over 230 days of sunshine each year and about 120 days annually with measurable precipitation and close to double the national average rainfall. No snow, of course, in this southern Florida location but the heat and humidity can be too much for some. In July, high temperatures reach a reasonable 91 degrees while the January low is 58 degrees. But it is the humidity that impacts comfort the most and you will feel it the moment you step outdoors throughout much of the…

Science and innovation columnist M. Venkataramanan calls attention to the unsafe example, "in the course of the most recent 100 years, the normal air temperature close to the world 's surface has ascended by somewhat less than one degree Celsius or one point three degrees Fahrenheit" (226). Many may laugh at this insignificant perception, yet climatologists anticipate that even this little change can bring about a noteworthy effect on the earth. Ken Caldeira, a columnist for Logical American…
