The carrying capacity of Wisconsin Fast Plants (Brassica Rapa) in a 2-liter bottle growing environment Introduction In this lab we conducted an experiment in which we created a habitat in which plants grown; We will determine if the plants will grow successfully in this habitat. We will plant “Wisconsin Fast Plant”seeds, also known as (Brassica Rapa). The Wisconsin Fast Plants are a small, fragile sized plant that has a short growing period and produces seeds at a high density. We will observe them as frequently as possible and record the heights each day we make observations.…
10/15/15: Today my experiment was approved. I plan to start on the 18th. 10/18/15: Today was the start date of my experiment.…
In this study, the effects of both varying temperatures and light intensity upon the photosynthetic rate of spinach leaves were observed. Using the ‘spinach immersion’ technique, the rate of photosynthesis under various conditions was quantified by observing the amount of spinach floating on top of a sodium bicarbonate solution. The sodium bicarbonate solution simultaneously supplied the spinach with carbon dioxide for use in photosynthesis, and caused it to sink. When the leaf underwent photosynthesis and produced oxygen gas, the leaf floated to the surface. It was hypothesized that an increase of either temperature or light intensity would lead to an increased rate of photosynthesis, to a degree.…
This ensured that the mass of the seeds was a constant variable in our experiment. Another person displaced the oxygen in the two plastic containers by completely filling them with water and then emptying them outside. They were sealed outside to trap the fresh air. This ensured that the oxygen levels were appropriate and consistent. At the same time, another person connected the carbon dioxide sensor to the interface and laptop and opened LoggerPro to begin collecting data.…
I chose thie project because it looked like fun and interested at the same time for me. I wanted to see which bag of radish seeds will grow when it was inserted inside a microwave. This experiment looks interseted because i wanna see what would happen to the seeds as soon as they last 10 seconds inside the microwave. This can be a good project for others it looks preety cool, it can be used in the REAL WORLD.…
In order to properly grow, plants need certain macronutrients and micronutrients. They need the macronutrients: nitrogen, phosphorous, potassium, calcium, sulfur, magnesium; and the micronutrients: boron, chlorine, manganese, iron, zinc, copper, molybdenum, and nickel. (3). Fertilizer enhances the growth rate of plants. Fertilizer adds nutrients and modifies the water retention and aeration of plants.…
Seed Dispersal Lab Max Bellinger Period 1 2-8-18 Seeds are dispersed three different ways, through water, wind, and by animals. When a plant goes through water dispersal, a light, buoyant seed is produced to be able to float down rivers, streams, and oceans. An example of a plant that uses the water dispersal method would be coconut trees that disperse the seeds through coconuts which can travel across the ocean and land on different islands or beaches During wind dispersal the plants produce lightweight, aerodynamic seeds that can be carried farther away…
Introduction: Leaf Disk float in water alone. When a solution consisting of a small amount of sodium bicarbonate is added to the water it causes the leaf disk to sink. As photosynthesis continues in the leaf disk it releases oxygen and causes the leaf disk to rise. While cellular respiration is occurring also the rate that the disk raise is an in implicit measurement of the net rate of photosynthesis. The independent variable in this lab is the solution and the light because it can be controlled.…
Data Analysis: Microwave Radiation and Plant Growth How does radiation affect the growth of plants? If seeds are exposed to microwave radiation then the growth process will increase. Get three seeds of the same type of vegetable (cucumbers were used in this experiment).…
Then, the nitrogen is absorbed into the soil and the plants take in that nitrogen. Lastly, the nitrogen from…
My hypothesis claimed that if seedlings are exposed to larger wavelengths of light, then their mass will gradually increase because of the greater amount of nutrients reaching the seedlings. The data provided during the experiment proves this hypothesis incorrect. Group D received 150 micrometers of light, which was the greatest amount of light for any group. According to the hypothesis, this plant would grow the most of the six groups. This, however, wasn't the case.…
Although plants need nitrogen to grow, plants only take in a small fraction of the nitrogen applied to their soil. In addition, nitrogen…
Abstract This experiment is about the effect of microwave radiation exposure on the percent that radish seeds germinate. The hypothesis in this experiment is if the radish seed is placed in the microwave for 8 minutes, then the percent of germinated seeds would be the lowest out of all the times. This experiment is important because if something happens and radish seeds are exposed to microwave radiation people would be able to know if the radishes would germinate if they knew the time they were exposed. This could also be used to find out if people could grow radishes in space because there is a lot of microwave radiation.…
Title Sugar water versus salt water: What effect did they have on seed germination? Purpose The purpose of this experiment was to figure out what types of water would have an effect and what that effect would be on seed germination. Background information Plants need nutrients to survive.…
Laboratory Report 2: Soil Texture, Bulk density and Porosity Introduction Soil Texture The classification of soil texture is determined by the percentage of each of the soil separates. Soil separates are mineral particles smaller than 2mm, and these particles are sand, silt and clay. These textures are separated by the size of the particles, with sand being the largest between 2mm and 0.05mm, silt at between 0.05mm and 0.002mm, and clay at <0.002mm.…
