Pure Water Test Lab Report

The purpose of this experiment is to observe the effects of Sodium Chloride (NaCl) on the germination rate of Wisconsin Fast Plants.

Firstly, for the setup of the experiment, two styrofoam cups were filled with two inches worth of standard, fertilized garden soil, next four seeds from from the garden seed, and the bird seed were placed an inch deep in separate cups. The seeds were blindly labeled, with one being labeled group A and one being labeled group B. This was so as to efficiently conduct a double blind experiment. The seeds were watered with approximately a teaspoon of water per day, and kept in a sunny windowsill. They were left in the windowsill for two weeks, and watered daily.

The results observed do not correspond with the outcome predicted by the hypothesis. Despite the nature of the subjects of the experiments, no substantial growth was observed. Only one seed of the 36 planted germinated, and it could only survive for a period of a week. The one seed that germinated reach a height of 1.2 cm. Table 1 presents the average growth observed in each quad. Each quad had a total of 12 seeds. No seeds were removed during the course of the experiment.

In generalization, there are a multitude of factors that could potentially influence the germination of a radish seed. This lab thoroughly exhibits the effect of water amounts on the germination of a radish seed. There is indeed an in-depth science behind the projected results, and overall of the effects water has on the germination of radish seeds, and the growth of plants in particular. Radishes themselves are moisture-loving plants; therefore, it is significant that they receive an adequate amount of water, allowing the soil to be moist, but not overly saturated (Biology Coach, 2015). In general, water is significant for the health of a plant in the way it transports important nutrients throughout the plant. From this point, nutrients are drawn from the soil and used by the plant. Seed germination itself is defined as the process where the seed sprout for growing, and future development into a plant. In order to germinate, the seed must have its essential needs met until it is capable of doing so: water, temperature, and sun. Therefore, during its early stages of growth, the seed will rely upon the food supplies stores within it, until it is large enough for its own leaves to begin making food through photosynthesis (Biology of Plants, 2016). Initially, the process of germination begins with the absorption of water y there seed, therefore, this absorption of water then activates an enzyme that increases

Table 2: Consists of color extract taken from a red cabbage for a natural indicator. The pH reading that was measured by using the pH meter and the result of the pH reading to determine whether the solution was acidic or basic.

This experiment was performed to give a better idea of interspecific competition and intraspecific competition between radish seeds and wheat seeds at high and low densities. By planting two species only pots and two combined species pots our results showed that the radish seeds performed better at both interspecific and intraspecific competitions and concluded that the lower the pot density the more resources and growth. 32 radish seeds were evenly planted in pot A1 followed by 32 wheat seeds planted in pot A2 and 16 of each radish and wheat seeds combined (32 total) planted in pot AB1. We repeated this procedure again but this time planting 96 radish seeds evenly in pot A2, 96 wheat seeds in pot B2 and 48 of each radish and wheat seeds combined (96

After extensive research, I believe that the more acidic the soil is, the slower it will be for the Fast Plants to grow. The soil’s pH is a crucial part in growing a healthy plant because “all plants require different levels for proper growth” (Lovejoy). The independent variable in this experiment is the Acidic buffer solutions; which consist of pH 2, 4, 6, and 7. According to Chemguide.co.uk, “An acidic buffer solution is simply one which has a pH less than 7.” It is very important that we as students understand the effects acidity has on plant growth. Studying the growth of the Wisconsin Fast Plant helps students have a firm understanding of this topic which in turn can help clean and prevent pollution throughout our country, making it a better and safer world for the

51) A botanist wanted to see if a new strain of corn could germinate in soil that was too salty for regular corn. She conducted a study on the germination success of seeds from the new strain that were exposed to various levels of salty soil, from zero to normal (100mg/L) to high (200 mg/L) to very high (400 mg/L) to normally lethal (800 mg/L)

The purpose of the pea seeds germination lab is to determine whether pea seeds will sprout with the absence of a complete water solution and replaced by Listerine Mouthwash. Water is the most basic and useful, natural resources for all living things. Water is extremely responsible for carrying all life functions within the cell. Life cannot exist on earth without the presence of water. In this lab we will investigate to see if seeds can germinate with a substance which its inactive ingredient is water. Since seeds require water in order for its embryo to rise up,

Title: The Affects of Acidic Solutions on Lima Bean Plants Abstract: To determine the best Ph to grow bean plants at maximal growth we have conducted a controlled experiment. First grew twenty five pea plants in twenty five individual hydroponic pots, with 250 ml distilled water, until they grew into mature plants. Then divided those plants into five different sections, each section has five plants. Then tested five different liquids all having different Ph levels. These liquids are distilled water, tap water, lemon water, Tylenol water and sparkling water.

AP Environmental Science-Acid Rain Labs:  Students were tasked with growing plants then using various concentrations of acidic water to gather qualitative data on plant growth and development in the presence of various acidic water mixtures over the course of two weeks. They then compared the Range of Tolerance of the plants to the local pH of rainwater to determine the expected impact on plants on the local level, as well as in other parts of the world.

The lab we conducted in class was to discover the effects that salt could produce on a controlled plant population. Instead of using different types of flora, we resorted to the use of radish seeds. We hypothesized that if a radish seed was placed into various dishes that contained a different levels of sodium, it would not grow in a solution with a heightened amount of sodium present opposed to a sodium-free solution.

This was unexpected because it was said that Belle radish grow best in 5.8-6.8ph but when the experiment was held the plant grew better in ph 4 than it did in ph 5. This was also found surprising because when soil is too acidic the plant would be shorter since the plant would not have the needed nutrients available but this experiment does not support that. A human source of error is that different rules were used and on rulers zero is not right at the tip of the ruler, for some rulers it’s a centimeter away and for others it’s 2 centimeters away but that was not consider and so that has effected the results. Another source of error is that the soil that was used might not have been the soil to grow this plant and so that could have affected the growth of the plants. In future experiments, the type of soil would be checked and research on the soil would be done to determine whether the soil itself would affect the plant in anyway.

Statement of Purpose The purpose of this experiment is to see what effect irradiation will have on the germination of radish seeds. The control group is the seeds with no irradiation. The control variable is the quantity of seeds.

Purpose: To see the effect of an acid introduced during seed germination, on the length of the plant roots. Also shows how salt can affect the seed germination. Acid can be introduced to seeds during germination if there is acid rain. Knowing the results of acid rain on seed germination will help us understand how to grow pants better, and how to have more successful germination. Salt can be introduced into a seed during germination because salt is put on roads and the salt builds up and can contaminate the soil. Knowing the effects of salt on seed germination will allow us to know for sure if the salt is affecting the plants growth or not.
