Laboratory glassware

The purpose of this laboratory experiment was to create a clear aqueous fertilizer that had a pH range of 6.0-7.0 with first three solid compounds the first day and then four solid compounds the second day. To complete this experiment, make calculations to find how much of each compound is needed in grams, use an analytical balance to measure out compounds accurately, mix the compounds in DI water until they are dissolved, test pH levels, effectively add acids or bases depending on pH level, and…

In the teaching profession as an Integrated Science teacher, for the past six years, I must agree that students do learn differently. As teachers we must cater to their various learning styles or we will be faced with students who gets bored or those who stare at us in bewilderment and confusion over not being able to understand the lesson. If we consider this very important fact that not all our students are the same, then when planning and preparing as good teachers we will include…

Introduction Innovations in technology made possible the creation of the bouncing ball, creditable to the chemist Norman Stingley. This bouncing ball originated from the concepts and shape of the regular toy ball. [1]. Balls have been in the industry for ages, as it needs chemical processes to be produced. As a result of innovation and optimization of processes the bouncing ball was invented using rubber at first, but produced by polymerization and use of plastics in the present. [2]…

144. This value is within the acceptable range, though it is not exceedingly accurate to the literature value of Avogadro’s number, and is most likely due to human error during the experiment.

For this assignment, I chose to interview Dr. Stuart McDaniel, an assistant professor at the University of Florida. Since Dr. McDaniel was a child, he loved the outdoors and was always interested in backpacking. He had a specific interest for maps and the distribution of plants. Plants on mountain tops never ceased to amaze him. He received is Bachelors of Science in biology from Oberlin College. In 1994, he moved to Paraguay as a Peace Corps volunteer in the Agroforestry department. After that,…

Abstract: Distillation is the process of vaporizing a substance or a mixture; condensing it through the water condenser and then collecting it in the receiving flask1. In this experiment, fractional distillation is used to separate organic compounds that have a minuscule difference of their boiling points. The objective of this experiment is to purify and separate ethanol and water by fractional distillation to achieve the 95% of ethanol and 5% of water; then determine…

different chemical and physical properties. This waste may be: • In the form of gas emitted from radioactive materials • In the form of liquid excreted from many research fields • In the form of solid ranging from glassware of hospitals and contaminated trash, radiopharmaceutical laboratories, reprocessing of spent fuel or waste from the nuclear power plants. Nuclear waste known as potential hazard to the human health, international and national guidelines standards radioactive waste with…

Plant Science - Seed germination and growth The research question: What is the effect of changing the pH of the soil on the germination and growth of mustard peas? Hypothesis: The greatest number of peas will germinate and will grow the most when the pH is 5 or 7. Theory: Enzymes play a vital role in the cells of plants (especially when growing) and enzymes work best when at their optimum pH value. Moreover, all chemical reactions have an optimum pH at which they work best (Howard and…

by Dr. Zia Ul Hasan (Professor, Department of Botany), Safia College Bhopal and the specimen voucher no.assigned was 344/Bot/safia/15 6.1.2 Drying and Size Reduction of Plant Material The leaves of Jasminum grandiflorum was dried under shade in laboratory. They were pulverized to make coarse powder. The coarse powder of leaves was passed through sieve No. 16 to maintain uniformity and stored in cool and dry place for further study. 6.1.3 Screening of Powder (Physiochemical Analysis)…
