Scientists have used science to scientifically prove that the science of cutting grass is actually quite simple. You just push your weapon over what you want to cut. Really, it’s that simple. Most manly men start cutting the grass along the edge of the yard to make sure they cut it straight and don’t skip any grass. When you get to a bed in the middle of your yard it’s usually best to cut along it the bed in a circular shape.
Temperature: Make sure the plants have the same temperature in its surroundings. Part 2 Purpose Getting rid of unwanted weeds in the yard. Research Whether or not home remedies or commercial herbicides are more effective and reliable. Reliable internet sources ending in .gov, .edu, .org, and or .fsu . and Weed control experts.
The Seaforth postman was a amateur botanist, and he was able to tell them where they could find the two shrubs they were looking for. Q5. What did forensic experts collect from Graeme's body and the rug for analysis back in the laboratory? A5. The thing which were collected from his body and the rug were twine, hair, grey clay, twigs and leaves and a peculiar pink sand on Graeme' clothes and shoes.
To test pH, cut off a strip of pH paper and press it into the soil. Wait a minute and then take it out. Record the color and if it is not visible, wipe it on a towel until you can properly record the color. (7. was exempt) Data: Test Observations/data Soil collection Collected in a patch of land with vegetation- grass and clovers. It had recently rained.
Physical Science Introduction to Scientific Inquiry Background Scientific inquiry is a process scientists use to study the natural world in order to answer questions or solve problems. It consists of several steps including asking questions, conducting research, forming hypotheses, conducting experiments, collecting and analyzing data, drawing conclusions, and communicating experimental results to others. In today’s activity, you will follow some steps of the scientific inquiry process as you investigate a natural phenomenon known as Charles’ Law. Introduction 1. Posing Questions Have you ever observed what happens to a sports ball when it is left in the sun all day, or left outside overnight?
The chemist transported the deer to the laboratory for further examination. As they continue on investigating, they found out wilted and discoloured grasses surrounding the nearby power-line poles. They speculated that herbicide had been used in a grass. Arsenic is the common ingredient in herbicides which is found in variety of forms such as arsenic trioxide, sodium arsenite, monosodium methanearsenate, and the last compound which is very soluble in water and active ingredient in herbicide the diosodium salt in methanearsenic acid, CH3As2(Oh)2. The herbicidal activity of disodium methanearsenate is when it reacts with sulfydryl group ( S-H group ) in the amino acid cysteine.
Although today scientists and theoreticians argue about variations applicable to specific problems, the scientific method has been accepted as the basis of scientific inquiry. www.HOLscience.com 17 ©Hands-On Labs, Inc.
The Three Causes to Soil Erosion The three causes for soil erosion are over cultivating, overgrazing, and deforestation. Over cultivation is the repeated process of the soil being plowed to control weeds; this exposes the soil to water and wind erosion. A solution to this would be no-till agriculture which is a technique that allows a planting apparatus connected to the back of a tractor to spray herbicide, cut a furrow, drop seeds and fertilizer in furrow and then closes it. At harvest time the process in repeated never leaving the soil exposed, erosion and water loss is reduced, and there is enough detritus including roots from the previous crop to maintain the topsoil. Another cause for erosion is overgrazing; which is the constant grazing of animals on plants without allowing the plants any recovery time.
Theories in Natural science are constructed to explain, predict, and master phenomena. They must be empirically testable or lead to retro dictions that are testable. This is extensively know as the scientific method. The scientific method is one reason is that we put our confidence in scientists. To yield and to develop their theories and conclusions.
Scientific reasoning is the process, which provides evidence for scientific theory. Induction is common throughout scientific reasoning since scientists’ use inductive reasoning whenever a limited data is used to form more general conclusions (Okasha, 2002). Induction is used to decide whether claims about the world are justified. Inductive reasoning is prevalent throughout science since it is common to have a sample size that does not include all of the possible test subjects needed for the study. This leaves the possibility that one of the test subjects not included in the sample could prove the conclusion to be incorrect.
