One of the main learning experiences of this lab is to learn the importance of calibrating a sensor. In most cases‚ a sensor will not have an output that is exactly what you need. An example of this is a strain gage. A stain gage gives back a voltage‚ but with that given voltage a distance can be found. Introduction: In this experiment‚ the QNET-MECHKIT was used. This board has multiple compact sensors that can be used for experiments. For this lab we will be using the strain gage to find the

Darwin’s Finches Lab In this inquiry lab‚ we explored natural selection using a laboratory. We wanted to see what was the effect of the type of food available on the frequency of different types of bird beaks. Our hypothesis was that If the type of the food available changes‚ then the frequency of beak types will change‚ because birds with beaks more suited to the available food will be more successful over time. Variables: Independent Variable: type of food available

Period 1 10/14/12 Enzyme lab Enzymes are biological catalysts that speed up the process of chemical reactions. They are also proteins‚ and most enzymes activities occur within organism. They decrease activation energy‚ energy that is needed to start a chemical reaction. Enzymes are substrate specific substrates ending in "-ase"‚ enzymes ending in "-ase". External factors‚ such as temperature‚ pH‚ and concentration of the substrate‚ affect the enzymes activity in the lab‚ pectase and cellulase will

Flame lab test Chemistry Introduction The lab test performed was to determine characteristic colors that were produced by specific metallic ions that are shown in a flame. This happens when an electron gains energy; the electron moves from an energy level that’s farthest away and to an empty orbital close to the nucleus with higher levels‚ so one of the electrons gives off energy. A flame test is a visual test where the energy is in the form of a color change and the change can

Helicopter Lab (Print and Due Monday) Problem: If we change the length of a paper helicopter’s wings‚ what length of wing will make the helicopter fall slowest? Hypothesis: If we increase the length of a helicopter’s wings then it wall fall slower because the wings will spin slower. Procedure: Materials: • Scissors • 3 Paperclips • Stop Watch • Ruler (metric) • Helicopter paper template(5cm X18cm) Step by Step: 1.) Gather Materials

Antivirus 2012‚ Bitdefender Antivirus Plus 2012‚ and Kaspersky Anti-Virus 2012. However‚ it is important to note that various sites and websites ranked the software differently. Kaspersky‚ more so than its competition‚ was consistently in the top 3 amongst the various review sites PC World‚ devduff.com‚ and pcantivirusreviews.com. The future of Antivirus software sales is expected to continue to be strong especially when you consider emerging markets like China and India. The prevalence with

Yak Lab Natural selection is the process by which favorable heritable traits become more common in successive generations of a population of reproducing organisms‚ and unfavorable heritable traits become less common. Natural selection acts on the phenotype‚ or the observable characteristics of an organism‚ such that individuals with favorable phenotypes are more likely to survive and reproduce than those with less favorable phenotypes. If all the offspring that organisms can produce were to survive

Lab Report: Toothpickase and Enzymes September 19‚ 2012 Olivia DePhillips Lab Partner: Joy Morgan Meyers Signature: Introduction Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process‚ called substrates‚ are converted into different molecules‚ called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts‚ enzymes work
