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
