Joshua Davis Teacher Class Date Title How often do we see some people in society now a days on their phones? Whether this be to someone checking their Facebook or just messaging their friends to let them know where they are. How often could you witness to how they could cause accidents such as not paying attention when crossing the road‚ crime such as the increase in phones being stolen‚ or car accidents in the split second in which one is looking down at their phone rather than paying attention

Negative Effects of Cell Phones As the technology of cell phones is increasing rapidly‚ the negative effects on people is growing fast as well . The first effect is being distracted while operating a Vehicle. There are different kinds of distractions for using a cell phone while driving but the common one is visual distraction‚ which is watching a cell phone screen instead of the road and trying to reach to the ring ton. Being a driver requires to have attention on the road but trying

The Effects of Cell Phone Use From now on‚ people will rely on phones more and more. A great many reasons lead to Cell Phone Use‚ I just list 3 main reasons. The first reason is that we used most of time going for working in fast-paced modern life‚ So we spent that time easily to watch movies‚ read news‚ chatting‚ and play games by phones‚ not only waiting. The second reason is that we can acquire a great many knowledge from web by phones. The last reason is that phones can bridge gap

How Does Temperature affect the Ability to Bounce of a Ping-Pong ball? Physics Design Practical Research Question How is the bounce-height of a ping pong ball affected by it’s temperature? This research questions aims to find out how the temperature of a ping pong ball affects the vertical height bounce‚ after being dropped from 1 metre. I will be measuring the bounce height using a video camera to find the heightest point. I will use the top of the ball for ease of results. Hypothesis:

Aim: The aim of the experiment is to test the effect temperature has on the activity of the enzyme rennin. Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC‚ which is the body temperature‚ where it will begin to slow down and stop reacting. I believe this will occur because enzymes have a temperature range at which they work best in and once the temperature goes out of this range the enzyme will stop working. Introduction:Enzymes are

Effects of Temperature and pH on Catalase Activity INTRODUCTION Enzymes are organic catalysts that spur metabolic reactions. The presence of an enzyme within a cell is essential in order for any sort of reaction to take place. All enzymes are complex proteins that act in an organism’s closely controlled internal environment. In such a homeostatic environment‚ the temperature and the pH (concentration of hydrogen ions)‚ remain within a fairly narrow range. Extreme variations in pH and temperature

Does Temperature of Kernels Affect Popcorn Yield? Project Design Plan This experiment will attempt to determine if the temperature that popcorn kernels are stored at will affect the amount of un-popped kernels when using a hot air popcorn popper. Popcorn kernels contain moisture inside of them which‚ when heated‚ turns to steam and expands that in turn causes the kernel to explode. Popcorn.org states that loss of moisture content can cause less yield amounts when popping popcorn (popcorn.org‚ 2014)

Understanding ion permeability is vital to knowing how it establishes a membrane potential‚ and how it eventually leads to the contraction of muscle cells. This was done using crayfish tail muscles. Lateral and medial tail muscles from the tail of a crayfish were excised. These muscles were then placed into solutions with different types of ion concentrations. Usage of different ion concentrations was necessary in practicing how to measure resting membrane potentials accurately. Measurements with
