Aim: To observe and describe an example of osmosis. Hypothesis: I predict that the water level will rise as the iodine stained water moves through the cellulose bag due to osmosis. The iodine is there so we can see this happening. Materials: * Dialysis(cellulose) tubing * Thistle funnel * Gas jar * Retort clamp and stand * Rubber bands * 50mL beaker * Iodine/potassium iodine solution * 5% starch solution Method: 1) Fill the gas jar to 3 quarters full with

For too many students‚ mathematics has little or no connection to their real-world experience. Previously‚ I thought that this stemmed primarily from a lack of understanding of mathematical concepts. While that deficiency certainly is an important factor‚ I am becoming more convinced that students don’t appreciate the power of mathematics largely because of an inability to represent‚ visualize and model word problems. Research has found that students solve math word problems using one of two

implementation in 2010‚ the Common Core Standards for Mathematics has proven to be ineffective in how it is delivered to students. Though the United States is a relatively affluent country‚ we unfortunately do not rank high in education in comparison to other countries. This research will uncover how the mathematics standards of the Common Core system are failing students in the United States. The goal is to expose where the United States Common Core mathematics education is falling short and how it can be

1) What is the purpose of ice or cold water? To cool down the gas so that it condenses and turns into a liquid. 2) when the gas collecting tube is upside down‚ give a property of this gas. It is less dense than air. 3) Why is a pencil used in drawing the origin line in chromatography? If pen was used‚ it will dissolve giving colours and so‚ the experiment won’t be accurate. Pencil doesn’t interfere with the results. 4) When using ethanol‚ give a better apparatus arrangement‚ and why? Cover

Justification of Higher Education Choices Choices: The two courses I have chosen are: Occupational Therapy and Computational Mathematics. I have chosen Occupational Therapy as will give the opportunity to learn within a small cohort which means there will be more support from my professors. It will also help me gain skills in problem solving and analysis‚ help me develop skills in teamwork and help me recognize the expanding types of work for occupational therapists. Also‚ I am interested in Occupational

Misfortune may be an actual blessing As a Chinese proverb goes‚ “Misfortune may be an actual blessing.” I underwent some events several years ago and I learned from them. My failure in the college entrance examination and the life of university in China was a precious memory as well as a good lesson for me. Finally‚ the chance to study abroad must be the excellent choice for me. I learned from my experience that something happened unsuccessfully might not be the eventual ending‚ and a turning point
