She performed a lab dissection demo‚ where she showed us how to properly dissect the clam and also gave us a few tips. Some external methods Kylie and I did were lining

There are two ways an interview can be written up. One is as a regular news story (either straight or narrative). The other is in a "Question and Answer" ("Q & A") format. News story style: Choose a Title (HEADLINE) · A good title should have something about the topic of the interview. It may also have a subtitle that includes the name of the person(s) being interviewed (magazine) · Summary of the topic (newspaper) Interviewer/author’s name (BYLINE) Where (geographic

IB Friction Lab Write Up 3. The slope of my graph represents the constant value for myu as the Normal Force and the force of friction are constantly changing. 4. The kinetic slope is the biggest by far because it represents the less coefficient of friction it has to overcome to move easier. 5. According to my data table‚ an increase in weight always‚ without fail‚ creates a greater force of friction. 6. An increase in weight does not affect the coefficient of friction by also increasing

common themes in these short stories in ¨Making Sarah Cry¨ and ¨Don’t Give Up The Fight¨. But there is one that pops out in the story and it is called overcoming obstacles. Sarah and Ava got bullied for being their own self.. While both of the stories share a common theme‚ but‚ their attitude is different. Sarahs attitude is different because she really didn’t talk to anyone. In ¨Don’t give up the fight¨ Ava did stand up for herself sometimes but she didn’t. Ava did not tell anyone about the boys

Introduction Enzymes are proteins that are involved in all the chemical processes in living things. As they are made of proteins they are affected by pH and temperature. Enzymes are catalysts; they speed up chemical reactions without being changed themselves. Digestive enzymes speed up the breakdown of large food molecules into smaller ones so that the blood can absorb them. Enzymes turn a large starch molecule into thousands of tiny glucose molecules. Enzymes end in ’ase’. There are thousands of

It represents the “backbone” of scientific research‚ as well as a useful method in everyday decision making. The steps involved in the scientific method would include‚ but not be limited to‚ the following: 1. Statement of problem 2. Information gathering on research 3. Formulation of hypothesis/possible

within a sample (in this case‚ the color dyes) through the use of chromatography. Utilizing the Rf value ‚ we can observe the ratio of movement certain substances make. The “movement” is determined by polarity‚ solubility‚ and the choice of solvent to be used. Each combination will result in a unique ratio‚ thus allowing us to compare unknown samples and discover their identity. The Rf value is essentially the rate the dotted sample will move in accordance to the solvent rising up the chromatography

Keep this growing tip and discard the rest. 6. Break up the root tip with the mounted needle (this is called maceration). Add one small drop of toluidine blue and leave to stain for 2 minutes 7.

varying temperatures are targeted towards being at 10ºC‚ 20ºC‚ 30ºC‚ 40ºC‚ and 50ºC. It is highly improbable that each trial for each of the 5 different temperatures will be the exact temperature that was targeted‚ so it’s just important that you end up having a temperature fairly close to the targeted temperatures so that the rates of reactions that you do receive are as correct as possible. The rates of reaction will be obtained using an apparatus that will guide the carbon dioxide gas being produced
