The poem harmonium examines the relationship of a father and son. I think Armitage has written this poem for parents and children as they would be able to relate to the emotions in the poem. The Author uses the Farrand Chappelette which is a type of Harmonium or small organ to help him reflect the love that he has for his father. In the first stanza the poet talks about the Farrand Chappelette which was “gathering dust” telling us that it is getting old and it was due to be taken to the skip if Armitage

ways. a. Raindrop Splash and Sheet Erosion. The first step in the erosion process begins as raindrops impact the soil surface. Raindrops typically fall with a velocity of 20-30 feet per second. The energy of these impacts are sufficient to displace soil particles as high as two feet vertically. In addition‚ the impact of a rainfall on a bare soil can compact the upper layer of soil‚ creating a hard crust that inhibits plant establishment. Sheet erosion occurs as runoff travels over the ground‚

Evidence of abuse is important so it needs to be preserved‚ this can be done in a variety of different ways. You can preserve evidence by only touching things you need to‚ securing all evidence somewhere it can not be tampered with by anyone‚ keeping logs of all conversations involving the abuse and keeping all relevant people up to date with details as often as possible‚ also taking photographs is a good way of preserving evidence. However the best way to preserve evidence is to inform the relevant

many clues left behind. The obvious would be a the body or bodies‚ clothing‚ and sometimes even the murder weapon. While these are great way to solve a case there’s another kind of evidence; trace evidence. Trace evidence are small pieces of evidence that are laying around a crime scene. There are many types of trace evidence some of them include metal filings‚ plastic fragments‚ gunshot residue‚ glass fragments‚ feathers‚ food stains‚ building materials‚ lubricants‚ fingernail scrapings‚ pollens and

Trace Evidence Trace evidence is an important part of a team in solving crimes in forensic investigations. According to Edmond Locard‚ there is specific that no matter wherever people interact with their environment or is physically involved in a crime often leaves something at or something away from the scene. Those in this category of evidence include many diverse types of macroscopic or microscopic materials that certain examples are easily visible to our “naked eye”. The subject is broad and

Big Morongo Preserve Located in Morongo Valley‚ lies a vast‚ exquisite place of unique wildlife and plants known as the Big Morongo Valley Preserve‚ which is tasked with promoting plant and endangered species growth. Since I’ve hiked the preserve previously‚ this will be a great experience to help with the preservation of the preserve. So I chose my project on September 7th to be the Morongo Preserve. On September 15‚ I read in the Big Morongo Canyon Preserve Fall 2017 newsletter that volunteers

Evidence of Photosynthesis Photosynthesis is the process during which a plant’s chlorophyll traps light energy and sugars (glucose) are produced. In plants‚ photosynthesis occurs only in cells with chloroplasts. Water (H2O)‚ carbon dioxide (CO2) and light energy are required. The light energy is absorbed by the green pigment‚ chlorophyll‚ and is converted into chemical energy‚ which causes the water drawn from the soil to split into molecules of hydrogen and oxygen. The hydrogen combines with
