The effect of Length on the overall resistance of a circuit. Research question: How does the length of the conductive putty affect the over all resistance of a circuit? This experiment will be discussing how the length of the conductive putty wire affects the overall resistance of a circuit. The variables for this experiment are being used for a number of reasons‚ however one of the main reasons behind choosing this experiment is investing how length of an object is affected be the resistance.

In “The Circuit” by Francisco Jimenez‚ Panchito feels ok about being a migrant worker. First‚ Panchito waited for a person to say some words and he got sad from not hearing those words. In the text ‚Panchito says‚ “ Ito signaled us that it was time to go home. “Ya esora” he yelled in his broke spanish. Those were the words I waited for twelve hours a day‚ every day‚ seven days a week‚ week after week‚ and the thought of not hearing the words saddened me”(Jimenez 10). This explains that

The purpose of lab number thirteen was to examine the response of the daphnia to a chemical stimulant. Also examined was how human resting heart rates differed from the daphnia’s. Stimulants are any substances that raise the levels of activity in the body. Stimulants could be a number of things such as physical or chemical. Physical stimulus usually deal with something that affects the five senses such as sight‚ hearing these could be attributed to loud noises or too much light going into your eye

Abby Goldschmidt Honors Biology 2° Mrs. Gempel September 3‚ 2015 Daphnia Lab Results Paper Abstract The goal of the study was to observe the effects of multiple chemicals on a Daphnia magna’s heart-rate compared to a control (pond water). The different chemicals were caffeine and alcohol. The heart-rate was the main variable in this experiment. The Daphnia’s heart-rate was observed for 15 seconds and then multiplied by 4 to show its heart-rate in one minute. This was repeated 4 times for each

AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas

First‚ the buffer was prepared by using the formula as follows: Figure 1: Calculation for prepare 0.1 M potassium phosphate buffer at pH 6 3.4007g of potassium phosphate was weighed and placed in 300 mL beaker. Then‚ 125 mL of water was added into the beaker that contained potassium phosphate. The mixture was dissolved using the stirring rod‚ and then the magnetic stirring bar was placed in the beaker for further dissolve when measuring the pH. The pH meter was used to measure the solution
