Sugar And Tonic Water Experiment
The purpose of this experiment was to discover if using sugar and tonic water with water would increase the growth rate of barley. In this experiment, we changed two variables, the independent variables sugar and tonic water. We added one tablespoon of each substance to four ounces of water which will be used to nourish the plant. We tested these experimental controls to determine if any of the substances would help accelerate the growth of the barley. If the sugar water or tonic water mixture successfully help accelerate the growth of the barley then we can conclude that they do help increase the growth process of plants and make them more efficient. We kept all other controls in this experiment consistent including the light and temperature. After completing the experiment, we found that neither of the two mixtures helped increase the growth of the barley.

In order to fully understand this experiment, the variables need to be explained. Barley otherwise known as Hordeum vulgare, is a hardy cereal that has coarse bristles

We are adding 1 tablespoon of tonic water which contains carbon dioxide. This is will help increase the rate of growth of the barley because plants take in carbon dioxide for photosynthesis. The ingredients of Tonic Water are macronutrients for plants to grow. These include carbon dioxide, oxygen, hydrogen, phosphorus, sodium, sulfur, and potassium. The tonic water should also help increase the rate of production because it contains macronutrients that are helpful to the growth of plants. In addition to testing Tonic Water, we are adding one tablespoon of sugar to the water. Sugar is a crystalline substance that typically consists of sucrose. By adding the sugar, this should help increase the rate of production with the Barley. This is because plants produce sugar to eat which helps them grow. By providing additional sugar, it should allow for a faster production of the

    2. Five variables that should be controlled during the experiment is the amount of sunlight, room temperature, amount of water, the time of day the plant is watered and the certain type of plant. To make sure the plants get the same amount of sunlight, make sure to put them both in the same spot so that one plant doesn’t get more sunlight than the other. To make sure they both stay in the same room temperature, put them both in the same room. With the amount of water come up with a measurement, and then make sure you give both plants that amount. Pick out a time of day for the plants to get watered make sure you water one earlier than the other since it is part of your hypothesis that they grow faster when watered in the morning. Finally, make sure that…

    My hypothesis is if sport drinks are consumed, then the reaction rate will improve. Sport drinks provide individuals with the required amount of water, carbohydrates and electrolytes (sodium and potassium) which is lost in sweat while exercising. Maintaining adequate electrolyte levels will enable better cell function, which is needed for muscle endurance, among other bodily capabilities when exercising. On the other end Glucose is an important source of energy, and water balance is required to maintain blood pressure and proper tissue functions. Even though water contains the required amounts of sodium and potassium, water…

    The question being asked here would be “Does a plant grow bigger if watered with milk? Or water?” In my opinion the answer would be milk because milk contains vitamins and calcium that water does not have, but the answer is to be found out later during the project. Well, it is known that for a plant to survive it will definitely need air, soil, water, light, and space to grow, but maybe if we replaced water with milk, plants could grow bigger and quicker, you never know. To test my theory, every morning before school I will water two of my plants with water like I regularly do, and two of my plants with milk which will be something new and will hopefully help my plants grow big and strong. The milk will probably help make the plants stronger. We humans need to have nutrients which we get from the food we eat that helps our bodies grow and stay healthy. Of course, just like us, plants also need the nutrients to grow. Milk actually contains quite a few nutrients, which may or may not help the plant grow bigger. Milk could also act as the plants fertilizer which could improve the plants growth. Those are just some of the ways that milk would help a plant grow.…

    Sensory adaption is an occurrence where sensory neurons become less sensitive to stimulation. When you have sensory receptors that change their sensitivity this is also a cause of sensory adaption. A lot of times we become use to things around us like normal sounds, smells and people we see every day. An example would be if you like to go to bars, bars are filled with people, smoking and drinking. You can walk in to a bar for five seconds and when you exit your clothes and hair will smell like smoke making it seem like you have been there for hours.…

    Enzymes are proteins that lower the activation energy needed for chemical reactions. The two main environmental factors that can affect the enzyme’s activity are temperature and pH, and each enzyme works best at a particular temperature and pH. The purpose of this enzyme kinetic experiment was to observe the effect of temperature and pH on the reaction of barley alpha-amylase enzyme with starch substrate and establish the optimum temperature and pH for this reaction. The optimum temperature and pH for the reaction of alpha-amylase and starch was predicted to be a temperature of 50°C and a pH of 5. The optimum temperature and pH for the reaction was determined by monitoring the reaction rate of alpha-amylase at different temperatures and pH’s by means of using a spectrophotometer to measure the disappearance (in absorbance) of the substrate starch. As a result, the absorbance of the substrate starch decreased at different rates for each temperature and pH as time continued to increase. The results showed that the reaction rate with the enzyme is highest when it reaches a temperature of 50°C and has a pH of 5. Therefore, a farmer should grow barley seeds in soil that has a temperature of 50°C and a pH of 5.…

    Cereal grains are essential dietary components that provide the world with many health benefits. Barley, a high-fiber and high-protein grain, is one of the most important and common cereal grains used for human food. Barley looks similar to wheat, however, barley has longer awns and it is often more yellowish in color. Most barley has a rough, inedible outer hull around the barley kernel. When it is hulled, it is tan in color and oval shaped. When cooked, barley has a rich nutlike flavor and a desirable chewy, pasta-like texture, which is the result of its gluten content. When barley is fermented, it is used as an ingredient in beer and other alcoholic beverages. Barley can be found in the market in a variety of different forms: pearl barley, hulled barley, pot/scotch barley, quick barley, barley flakes, and barley grits. All these forms are an excellent source of starch and provide a number of beneficial vitamins and minerals.…
