caffeine on plant growth | Description This science fair project was performed to find out the effect on plant growth of adding caffeine to the soil. The experiment was done by using mung bean plants and watering them daily with water‚ water mixed with caffeine and with a coffee mixture. Hypothesis The mung beans watered using the coffee mixture will grow the fastest. Overview Caffeine and plant growth The effect of adding caffeine to the soil and its effect on plant growth is a subject

What affect does fertilizer have on the rate of growth in plants over a certain period of time? When tested‚ there is no affect on the growth of plants from a change of an environmental factor‚ such as an exposure to fertilizer. By changing the independent variable (whether or not the plant was planted with fertilizer)‚ you are testing to see how the dependent variable would change (the growth of plants). In order to assure that there is no experimental error‚ a control must be kept to produce the

Growth of Plant under Different Colored Light Problem: Does the color of light affect the plant growth? Hypothesis: Red color will have the most impact on the plant growth‚ meanwhile; black will have the least impact on the plant growth Variables: • Dependent Variable is the color of light • Independent Variable is the type of plant used Materials/Apparatus: • Plants (of the same type) • Water • Ruler • Colored Construction Paper • Colored Transparent Print Paper • Lamp with Incandescent

In the beginning salt water and regular water got along. They all lived in the same ocean and each droplet would live in harmony. They shared the undersea environment with all the fish and sea plants. Some plants and animals needed salt water more than fresh water and some needed fresh water more than salt water. This is where the problem all started. The fresh water began to become jealous because the salt water was mocking the fresh water about them being the best type of water. It started out

Introduction For this Science assignment‚ I chose to find out if the color of light a plant receives‚ affects the plant growth. Light is electromagnetic radiation that comes in waves‚ the basic units of which are called photons. Plants use light to turn carbon dioxide into sugars necessary for growth‚ a process called photosynthesis. Sunlight is a full spectrum of different wave lengths of light. Seen through a prism‚ this spectrum turns into bands of color: red‚ orange‚ yellow‚ green‚ blue‚ indigo

The rice plant has tillers which are a characteristic of grass plants; however they have recognized a way of growing the plant which causes it to create the best grain possible. Discussion: Vegetative: In this stage the plant germinates and gradually grows taller and leaves emerge at steady intervals. Germination: The root elongates through the seed coat and anchors into the soil. The primary leaf (coleoptile) also elongates and breaks through the seed coat. Early seedling growth: The first

Fresh water always freezes at 0℃‚ but that is not always so for water with salt inside. The higher amount of salt there is in the water‚ the more the freezing point decreases. So‚ salt water freezes later than freshwater. The exact measurement of how they impact each other is this: every 5 psu increase‚ the freezing point decreases by 28%.. In an ocean‚ there is frazil and brine. Frazil are ice crystals suspended in water‚ and they are made of nearly pure freshwater. Frazil is the first stages of

an egg will float in salt water. The question is how much salt is needed to be added to the water to make the egg float. The problem is that no one knows how much salt is needed to make an egg float. Hypothesis It will take at least three teaspoons of salt to be added to the water for the egg to float. The reason why I think three teaspoons of salt will need to be added to water for the egg to float is because the egg a density that is lower than the density of the salt water.

about the effect of soapy water on plants. The hypothesis was‚ “If plant A is given 10 ml of plain tap water every other day for two weeks and plant B is given 10 ml of soapy water (5 ml softsoap and 5 ml plain water) for the same amount of time then‚ plant A will grow at least 3.0 cm taller than plant B.” The Hypothesis was supported. Plant A grew 13.6 cm while Plant B grew only 5.2 cm. The Independent variable was water‚ food‚ plastic cup‚ sunlight and soapy water. The Dependent Variable was
