I. Imagine what would happen if we woke up tomorrow to a world with no technology. A world with no modern transportation‚ no computers‚ or cellphones. How could we possibly travel to work? How could we work? How could we communicate? II. The fact of the matter is that our society could not travel to work‚ we could not work‚ and we could not communicate because we are too dependent on technology to take care of us. III. Today you will learn three ways why society is too dependent on technology; the

for the pH concentration experiment were put together by using a 10ml-graduated cylinder to obtain 4ml of each pH buffer to insert into cuvettes‚ a micropipette was then used to obtain 0.5ml of catechol and 0.5ml of the catechol oxidase. The pH buffer was made first to avoid any denaturation of the catechol oxidase. Our positive control for this experiment was pH 7 because that is the pH level of most cell membranes in the cytoplasm (Whitson‚ 2016.) Our negative controls varied for each pH buffer

The Symbolism of Colors in F. Scott Fitzgerald’s‚ The Great Gatsby Color has been known to carry emotion. It has the power to make us feel warm or cool‚ eerie or pleasant. F. Scott Fitzgerald does just that in one of the greatest pieces of literature out there‚ The Great Gatsby. He manages to capture a variety of different essences and takes us with the characters in the downward spiral that is The Great Gatsby. In physics‚ a color is a visible light with a specific wavelength. Black and white

CAT - Measuring the pH of common household substances 1. Predict the pH value of substances & estimate the pH value by using the universal indicator. 2. Use the indicator to identify acidic‚ basic‚ and neutral substances found in any home 3. Classify household items as acids and bases 4. Collect organise and analyse results in tables and graphs (if necessary) 5. Analyse results and explain the reason the substances have the pH obtained. Aim – To use a universal

Kindergarten This document provides an overview of a suggested sequence for teaching and learning words‚ letters and sounds in kindergarten. It explains what this learning involves‚ why it is important and how it might be taught enjoyably and effectively. The two other documents in this kindergarten sequence give guidelines for teaching‚ and define in detail what needs to be learnt‚ provide ideas for how it can be taught and how new learning may be monitored and assessed. http://ecm.det.wa.edu.au/connect/resolver/view/PDLK001/1/PDLK001

Throughout the experiment‚ there were 3 significant error I made. Firstly‚ at first when I conduct my experiment‚ I measured 10g of ascorbic acid powder and mix it within 1 litre of water. I believed that by having the solution prepared before putting in the d-block elements would save time overall. Unfortunately‚ the data was all over the place‚ this is because the later I conduct the experiment‚ there is a higher chance of oxidation occur in the ascorbic acid solution as it have a direct contact
