Approximate Time Required to Complete the Project Two weeks To understand the effects of acid rain on plant growth over the short term and extrapolate the results to better understand the effects of acid rain at larger scales. These gases convert back to acids when they contact water. Acid rain can be a problem when environments lack strong bases to neutralize the acidity.
In your lab notebook, create a data table like this one to record how many leaves in total are on the duckweed plants in each container over time.
Note that the total number in each container should be 20 on Day 1, so this has already been filled in for you. Make two line graphs of your results, one for the snails living and one for the number of leaves on the duckweed over time.
You can make a graph by hand or use a computer program like Create a Graph and print out your graph. For the graph showing the snails living, put the time in days on the x-axis the horizontal axis and the number of snails alive on the y-axis the vertical axis.
Make a different line for each container, being sure to also list the pH of the container. For each graph showing the number of leaves on the duckweed, put the time on the x-axis and the number of leaves on the y-axis. Analyze your results and try to make conclusions based on them. Did the aquatic organisms respond similarly or differently to the changes in pH of your environment?
What is the viable pH range for each organism? Which organisms are the most sensitive or the most resilient strong when it came to changes in acidity? If you like this project, you might enjoy exploring these related careers: Marine Biologist Do you enjoy going to the ocean?
Do you like examining all of the marine creatures in tide pools? Do you read up on the different kinds of ocean mammals and fish for fun? If this is the case, then you may be the right fit for a career as a marine biologist. Marine biology is the study of ocean aquatic organisms, their behaviors, and their interactions with the environment.
Because this field of study is an intersection of zoology, biology, and technology, marine biologists can apply their knowledge in many different ways.
Read more Environmental Scientist Have you ever noticed that for people with asthma it can sometimes be especially hard to breathe in the middle of a busy city? One reason for this is the exhaust from vehicles. Cars, buses, and motorcycles add pollution to our air, which affects our health.
But can pollution impact more than our health? Cutting down trees, or deforestation, can contribute to erosion, which carries off valuable topsoil. But can erosion alter more than the condition of the soil?
How does an oil spill harm fish and aquatic plants? How does a population of animals interact with its environment?
These are questions that environmental scientists study and try to find answers to. They conduct research or perform investigations to identify and eliminate the sources of pollution or hazards that damage either the environment or human and animal health.
Environmental scientists are the stewards of our environment and are committed to keeping it safe for future generations. You might see shrimp from Thailand, salmon from Canada, and flounder from the United States of America. Some of the fish is wild, caught by fishermen from the open seas; but these days, a lot of fish and shellfish is farm raised.
Aquacultural managers direct operations on farms and fish hatcheries that cultivate ocean and freshwater fish for human consumption, recreation, and research. The field of aquacultural management is an example of biotechnology.This science fair project idea researches the effects of acid rain on plant growth.
Guided Lessons Learning Library Teaching Tools. Acid rain occurs when low pH acids pollute our air and are deposited back on earth’s surfaces when it rains, snows, sleets or hails.
Concepts and Questions to Start Background Research.
Background Research Acid rain is the term used in environmental science, which represents mixing of environmental pollutants with rainwater. The combination of gases and water form a chemical reaction, which then forms acid rain. The major pollutants that cause acid rain are sulfur dioxide (SO2) and nitrogen oxides (NOx) produced during . Acid rain is becoming more and more of a problem for our world. Outside of industrial pollutants, like nitrogenous and sulfuric oxides, even excess carbon dioxide can affect the pH of rainwater. One question that arises is ‘How will agriculture be affected?” plants rely on rainwater, and obviously have no control over its acidity. Acid rain is a popular phrase used to describe rain, snow, fog, or other precipitation that is full of acids that collect in the atmosphere due to the burning of fuels such as coal, petroleum, and gasoline.
Acid rain. PH. Sep 03, · Phytic acid is the principal storage form of phosphorus in many plant tissues, especially the bran portion of grains and other seeds. It contains the mineral phosphorus tightly bound in a snowflake-like molecule.
Effects of Acid Rain Lab Objectives: To visualize the effects of acid rain on a living organism. Questions: How does simulated acid rain affect the germination of a lima bean? How does acid rain occur?
Do background research. How does acid rain affect plants? Is it currently a problem for plantlife? Hypothesis; Data: This section should.
Welcome to the web site for the Dihydrogen Monoxide Research Division (DMRD), currently located in Newark, monstermanfilm.com controversy surrounding dihydrogen monoxide has never been more widely debated, and the goal of this site is to provide an unbiased data clearinghouse and a forum for public discussion..
Explore our many Special Reports, including the DHMO FAQ, a definitive primer on the. Acid rain is rain that has been made acidic by certain pollutants in the air. Acid rain is a type of acid deposition, which can appear in many monstermanfilm.com deposition is rain, sleet, snow, or fog that has become more acidic than normal.
Natural gas, as the cleanest of the fossil fuels, can be used in many ways to help reduce the emissions of pollutants into the atmosphere. Burning natural gas in the place of other fossil fuels emits fewer harmful pollutants, and an increased reliance on natural gas can potentially reduce the emission of many of these most harmful pollutants.
