DESIGN AN EXPERIMENT: THE BIGGEST BLOWER EXPERIMENT Design an Experiment: The Biggest Blower Experiment Problem Statement: You have a pack of Hubba Bubba Bubble Gum. Does the amount of sugar in this gum affect the size of the bubble you blow?? Hypothesis: I think that sugar in any gum affects the size of the bubble you blow. I think this because I was watching “The Next Great Baker” and someone was melting sugar and when it cooled off a little he used a balloon blower to make bubbles out of

Sometimes the data we need may not be available from internal or external sources. In such cases‚ we may have to obtain data by conducting our own survey or experiment. In a survey‚ we do not exercise any control over the factors when we collect information. For example‚ if we want to collect data on the money various families spent last month on clothes‚ we will ask each of the families included in the survey how much it spent last month on clothes. Then we will record this information. A survey

Design Experiment: Enzyme Inhibitors. Research question: What is the effect of adding lead nitrate solution on the activity of amylase enzyme? Aim: To test the effect of adding nitrate solution on the activity of amylase. Background Information: Inhibitors are molecules which repress or prevent another molecule from engaging in a reaction. They are substances that attach themselves onto an enzyme and reduce or prevent the enzyme’s ability to catalyse reactions. Competitive Inhibitors are inhibitors

Nonverbal Experiments Everyone will do Experiment #1 – A Mute Point Choose 3 additional experiments – follow the directions and have fun! 1. A mute point – We will all do this on the same day! You can not talk for one entire day. Document your frustrations‚ your “oops” moments‚ reactions from others‚ and if any new revelations came about from not speaking. Make sure you wear your sign! 2.

Aim: The aim of the experiment that was carried out was to see‚ at what temperature and in which standard solution‚ does the amount of dye left in the boiling tube had the highest percentage transmission. Beetroot was used for the experiment because it was easier to see the dye after the practical was completed. Putting beetroot cylinders into different boiling tubes‚ which contained

Biology College of Science De La Salle University – Dasmariñas Dasmariñas‚ Cavite Philippines ABSTRACT This experiment was performed to learn the technique of acid-base titration and to compare the efficiency of commercially available antacids by looking at their weight of HCl and weight of antacid values. The analysis of antacid tablets was highlighted in this experiment. The efficiency of antacid tablets was determined and compared when the number of grams of HCl can be neutralized by

choosing the pain of discipline over the ease of distraction. And that’s exactly what delayed gratification is all about” I think that is very true. Delayed gratification is just waiting for something better. If a kid doesn’t pass the marshmallow experiment parents start to wonder what they should do. Mischel states he would remind the parents that there are a large number of cognitive skills that can be used and practiced if kids have a serious self-control problem. At one point Mischel used poker

determination. Calculations : (C1) Calculate the amount of NaOH used in the titration. (C2) Calculate your solubility of potassium hydrogen tartrate in M. (C3) Calculate your solubility product‚ Ksp‚ of potassium hydrogen tartrate. Post lab Questions : (Q1) What are you assuming the filtrate is‚ unsaturated‚ saturated‚ oversaturated‚ or supersaturated? (Q2) What would happen to the solubility and Ksp(that you calculated) if you started with 0.000001g of solid potassium hydrogen tartrate
