bath and body wash on millet seed growth. This experiment was conducted to determine what effect a household chemical would have on the growth of a plant. Everyday multitudes of chemicals are washed down the drains inside of our homes; many of these same chemicals are then being introduced into the environment through our water sources‚ such as rivers. This experiment will test the effect of all-natural bath and shower gel would have on the growth cycle of millet seeds. The all-natural bath and shower

Indoleacetic acid (IAA) stimulates internodal elongation‚ rooting‚ and leaf abscission. B-nine reduces internodal elongation. The control substance is the independent variable in the experiment. Four planting pots‚ which were divided into three parts‚ were used for planting the seeds. Two seeds from each type of plant were put in the soil of one compartment of the four planting

Wildfires are extremely dangerous. They pose a serious threat to all kinds of life. In a sharp contrast to these are prescribed burns which are fires that are purposefully set and controlled. They help to prevent‚ and limit wildfires in places where they cause damage‚ and to replace wildfires in habitats which rely on the regular occurrence of fire. Prescribed burns are fires which are purposefully set in order to eliminate some of the problems which arise from uncontrolled wildfires. Back burning

Questions and Hypothesis: Seed germination‚ plant growth‚ and sprouting of leaves are affected by several factors: supply of nutrients‚ water‚ exposure to sunlight‚ and conditions of surroundings. Due to certain stimuli in the surroundings plant “hormones” cause plants to behave in ways that ensure the most efficient use of resources while preserving the most energy. One stimulus to consider‚ is the exposure of plants to sunlight; when plants are just sprouting and are underground‚ the sti

He sees The Tollund Man as a timid victim of circumstances and feels sorry for him and his plight.

in class is to see whether or not competition between plants for water and sunlight will affect their growth. To do this we will set up two pots with soil in them‚ one will have a radish seed inside and the other will have a radish seed surrounded by crest seeds. The independent variable will be the amount of seeds in each pot and the dependent variable will be the height of each radish at the end of the experiment. The constant factors will be the amount of sunlight each pot receives; this will be
