Arlind Mara Paper Towel Lab Report AP Biology 15 September 2011 Which Towel is The Quicker-Picker Upper! To determine which of the most popular paper towel brands such as Bounty and Marcal would be the Quicker-Picker-Upper I conducted the following experiment during which I dipped 6in X 6in squares of paper towels into 100mL and measured the amount of water absorbed by the towels in 20 seconds. After averaging all 3 trials for the paper towel brands that I tested I arrived to the conclusion

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

chemistry. The data was gathered using an electronic analytical balance. This equipment has a precision and accuracy that exceeds 1 part in 106 at full capacity. It can measure from 0.0001 mg to 30 g. The electronic analytical balance used in the lab features a taring control that disregards the weight of the container on the pan. Thus‚ the value displayed on the balance only refers to the sample in the container. Ten 1-peso coins were then collected as samples. Each coin was weighed on the balance

Education Program CHROMATOGRAPHY (Adapted from: Forensic Science Activities. University of Colorado Boulder Hughes Initiative. .) DESCRIPTION: Students will use paper chromatography to separate ink molecules and identify the pen used on an unknown sample of handwriting. Students will graph and analyze data they collect using paper chromatography. PURPOSE/GOAL: Students will be able to: • Gain understanding of the purpose of chromatography. • Measure and graph pigment separation. • Use evidence

Objective of experiment * The objective of the experiment is to assess the effect of different pH conditions on enzyme activity. Hypothesis * I feel the pH affected the enzyme activity to produce product. Prediction * If the pH affected the enzyme activity to produce product‚ then rate of reaction will change. Procedure * The procedure that we followed was to take two test tubes and label one pH2 and one pH10 and incubate 1 ml of each solution for 30 minutes. Then after 30 minutes

The Math lab evaluation Have you ever been to a place that is depressing‚ gloomy‚ and absolutely apathetic? If not then by all means make a point to go by and visit the math lab. As a student of the University of South Alabama I have been asked to evaluate the math lab by my supervisor. My supervisor had received various complaints by students‚ for that reason I have been asked to observe the math lab record what I saw and write down any suggestions for change. During this evaluation I will discuss

GRAVIMETRIC ANALYSIS OF A CHLORIDE SALT (2013) Report By: ____________ Lab Partner: ___________ Group: CHEM 1001 Tuesday AM‚ Group H Purpose: This lab was conducted in order to determine the content of chloride in an unknown salt‚ using gravimetric analysis. Theory: The salt chloride content is easy to find because it is slightly soluble‚ making it possible to turn it into a precipitate. A precipitate reaction can be done using silver
