Duckweed Lab Report

748 Words3 Pages

“Duckweed Recap” The duckweed lab was done to see the effects of road salt on the production of duckweed fronds. The purpose of this lab was to see if the salt concentration significantly affected the growth of the duckweed fronds. We had five different glass jar, one being a control with no salt in the water solution and four jars with different amounts of salt water concentrations and five ml of miracle grow in them. We started the experiment by putting four healthy and green duckweed plants with two fronds on each in every jar. Then we observed them on different days describing them with qualitative and quantitative observations. Before the lab I expected the duckweed to show some sort of effect to the salt water because it is an indicator species. …show more content…

Before this lab I knew road salt was used on the roads to help melt the ice in winter. To melt the ice I knew that the salt absorbed some water. Also you do not want to use soft water to water plants because the soft water has gone through the water softener, which uses salt to soften the water. When we first started the experiment the duckweed fronds were green and healthy. Also each container had four plants with two fronds on each plant. The three classes average quantitative data is 15.9 fronds for the 0%, 7.5 fronds for the 10%, 8.1 fronds for the .1%, 10.7 fronds for the .001%, and 11.9 fronds for the .00001%. mY groups quantitative data in the final observation day was 15 fronds for the 0%, 8 fronds for the .10%, 8 fronds for the .1%, 10 fronds for the .001%, and 14 fronds for the

    1007 Words  | 5 Pages

    TASK: When a ball is dropped from a height, it loses some of its energy and each bounce gets shorter. Your investigation will determine the effect of original drop height on bounce height. From this, energy loss can be calculated between bounces. As different groups will be using different balls, you will be able to compare energy loss with different balls. You are required to present your findings in a lab report format, which has been detailed below.

  • Essay On Road Salt

    553 Words  | 3 Pages

    How Road Salt Effects Vegetation Putting sodium chloride on highways and sidewalks can cause detrimental effects on vegetation. Sodium chloride and many other chemicals in road salt have been proven to harm how plants and grass grow. When sodium chloride and the chemicals in road salt interact with grass they can ruin the grass 's development and even cause it to die. Grass growth can be shown with four stages of maturity (Discuss the Basics of Grass Growth). The seedling stage happens when the grass stem starts to protrude from the soil, but the roots have not begun to develop underneath the soil, the leaves have begun to develop as well.

    Addictive Behaviors This study, “Heavy Episodic Drinking and its Consequences: The Protective Effects of Same-Sex, Residential Living-Learning Communities for Undergraduate Women” aims to find the impact the environment has on drinking and alcohol abuse. The areas of comparison are single-sex resident living communities, mixed sex residential learning communities, single sex non residential learning communities, and mixed non residential learning communities. This study can possible lead to a solution to underage drinking in colleges, if it is valid and significant. If it does not lead to a solution, it can still provide insight as to the overwhelming number of underage college students who drink.

  • Plant Growth Experiment Essay

    The data used in this experiment is the average of all the plants height, and does not count the length of the roots. This is because the averages will provide a more even set of data because not all plants are exactly the same and due to genetic variation some may grow higher or shorter than others. The data being analysed is the height it grew from when the hormones was placed on the plant (day 4), this is to ensure that if a plant grew taller or shorter than the others from day 0 till day 4 it would still be accurate when comparing to the other tests. Primary Data: In this experiment the average growth ranges from 0.7cm to 10.2cm in six days from when the hormones were placed on the plants for dicots, and 5.9cm to 10.4cm from when the hormones were placed on the plants for monocots.

    A report on the effects of Lead and different pH levels on Lemna minor, which is a species of duckweed. The pH of water influences the forms of metals and metal oxide in aquatic systems. This is because pH controls solubility of metals as well as concentration. Decreasing the pH of a solution causes an increase in the free metal ion concentration of the solution. Due to this fact, it was stated that metals in acidic waters have more of a chance of being toxic than metals in neutral water.

    We went to the salt marsh at Wrightsville Beach, North Carolina. Starting at the water line we measured 100 meters into the salt marsh. At every 10 meters we stopped and laid a quadrat down, which is just a square made out of pipe. We counted the number of each species and organisms we saw in each quadrat and also measured the height of each plant. We repeated these steps until we got to the 100 meter mark, which took us eleven quadrats total.

    The Detroit image of the abandoned warehouse coveys what the oil industry chooses to reveal to the public. Edward Burtynsky’s Fisher Body Plant #1 photo taken in Detroit, Michigan depicts an abandoned building that has graffiti and trash covering the worn, brick wall with broken glass windows on the upper third of the photo. The bottom third of the photo is a puddle of water that stretches to the edge of the photo and reflects the building in the water. The water in the lower third can be interpreted as oil as it looks black and murky like oil and the broken building represents the oil industry. The “oil” only reflects a select part of the building and more specifically it reflects the transition between brick and glass.

    This suggests that the lights which produced heat are less suitable for use with the growth of these plants. The hypothesis was that the heat producing bulbs would make the plants produce more oxygen as they would be photosynthesising more, however the results disprove this idea. A possible reason for this is that the plants used were both aquatic and so are more used to cooler temperatures. Therefore their optimum temperatures for photosynthesis would have been lower than the usual for land plants, suggesting that the warmer temperature reduced their efficiency.
