Title: The Effects of Microwaved Water on Plant Growth Problems: 1. What are the factors that make the microwave harmful? 2. What happens to the water (when microwaved) that causes it to affect plant growth? 3. What are the effects of microwaved water on the growth of plants? Hypotheses: 1. The micro wavelength radiation the microwave contains makes it harmful. 2. The water undergoes ionizing radiation which causes it to affect the growth of the plant 3. The growth of the plant

In this experiment‚ we will be finding out what happens to gummy bears when put in different solutions to observe and predict why they dissolve‚ shrink‚ or grow in each of them. The solutions that we are using are 2 % Low-Fat milk‚ apple cider vinegar‚ filtered water‚ sugar‚ baking powder‚ and salt. The prediction is that when the gummy bears are in baking powder‚ they will be hypotonic‚ but will be hypertonic in sugar. Our controls are the same intervals of time and the same type of gummy bear

The Incredible Egg Procedure: On October 5‚ I gathered a large Styrofoam cup‚ an egg‚ some vinegar‚ some corn syrup‚ and some water. Before I started the lab‚ I weighed the egg on a scale. Because the egg would just roll off the scale if I set it down by itself‚ I weighed the cup‚ and then added the egg. After I knew how much the egg weighed‚ I poured enough vinegar in the cup to submerge the egg. I then covered the top of the cup with plastic wrap and set the egg aside. The next day‚ I washed

Question: Why would sensing and responding to vinegar be important to an organism? -It could train them to respond to certain smells and respond in a certain way. How would natural selection affect an organism’s ability to sense and respond to this stimulus? -The organism depends on its ability to sense and respond. The organisms could compete for water or hydration. What other types of stimuli would be important for the organism to respond to? - An organism that is used to light is

The first step was to prepare 400 mL of an 0.1 M solution of NaOH. This was done by diluting from the 6 M solution that was provided. Next‚ 0.715g of KHP was weighed using the glazed paper and the triple beam balance. The KHP was then transferred to the 250 mL Erlenmeyer flask. Using a graduated cylinder‚ 50 mL of deionized water was measured and added to the flask. The KHP was dissolved in the water‚ and few drops of phenolphthalein were added. Moreover‚ the burette was rinsed with deionized water

arnibal (brown sugar) and vinegar. I use arnibal because it is sweeter than white sugar. Statement of the Problem: This study ought to answer the following problems: 1. Can we produce our own carbocistine out of lagundi leaves‚ and arnibal? 2. Is the carbocistine effective? 3. Is the vinegar an effective preservative? Carbocistine – cough medicine Lagundi – Scientific name: vitex negundo l. English name: fine leaved chaste tree‚ Tagalog name: lagundi‚ kamalan. Vinegar – a sour liquid obtained

INTRODUCTION: Nowadys‚ indicators have become technologically advanced and can be used for the main purpose of indicating whether something is acidic‚ basic or neutral. This is possible because in solutions of different pH‚ the colour of the inidcator will change simultaneously with pH change. This is made possible by pigments in the indicators. Hand made indicators include universal indicator‚ methyl orange‚ phenolphthalein and many more. Acids and bases are diverse in this world. They are everywhere

diffusion of water across a semi permeable membrane. Over three days we tested the egg in three different solutions to observe the changes. On Day 1‚ the main question we answered was what happened to the egg when it was placed in vinegar? Before doing this I came to my hypothesis was that the vinegar would eat away at the shell and eventually dissolve the shell since it is an acidic solution. Things with acid are corrosive and sometimes poisonous so they eat away at things. On Day 2‚ the main question we had to

For old pennies‚ soak the coin in vinegar for at least 24 hours. For bronze coins — usually ancient coins — soak in distilled water (the minerals in tap water can further taint the coin’s surface if soaking for a long time) or olive oil — olive oil is a very gentle way to clean coins‚ but you may need to soak them for several weeks. Silver‚ copper‚ and nickel-clad coins can be soaked in distilled water or‚ to remove tough stains‚ white vinegar. A 6-minute soak in lemon juice may also

CHAPTER 1 INTRODUCTION 1.1 PRELIMINERIES Due to highly development of chemical and biochemical industries‚ acetic acid has largely produced to fulfil the needs of world demand in production of daily used products and for pharmaceutical needs. Therefore‚ this study is carried out to introduce the production of acetic acid using biological pathways which includes the used of microorganisms. In this chapter will briefly explained on the knowledge about acetic acid and the microorganism
