The tiles are subject to cracking when hit by hail or when they are walked on. Slate is the ideal material for the growth of moss and algae too, which won't necessarily harm the roof but cleaning the tiles might lead to cracking from walking around on the roof or using a power washer. Metal roofing is also very durable and it doesn't crack. It may dent if hit by a hailstone, but the dent…

The article “Ocean Acidification is Bad, and It’s Getting Worse,” was written by Pierce Nahigyan. Nahigyan is the Editor-in-Chief at Planet Experts, he has a degree in B.A in Sociology and History from Northwestern University. Upon reading some of his other articles he has written it is clear that Nahigyan is an excellent writer but has a hard time staying unbiased. While most of his research has scientific backing, Nahigyan has habit of overstating the facts that back his claims. I believe…

species ever discovered in Hawaii. The can be spotted from the beach. Hawaiian Green Sea Turtles are the largest hard-shelled turtles in the ocean (Murphy). They are regularly found resting under underwater ledges, basking on beaches, and nibbling on algae in shallow waters. Sea turtles normally live in water that is fairly warm. The average shell length of an adult green sea turtle is 4-5 feet long and weight of 250 pounds, although they can grow as large as 500 pounds.…

diversification of the first vascular plants, i.e., plants that alternate generations between the sexual gamete production (gametophyte) and the sexual stage (sporophyte). Through this period would have arisen three types of flora beyond red, green, brown algae, and ditoms: these are ferns, lycopods and sphenopsids (flora 1), the gymnospears, or vascular plants able for producing naked…

Omega-3s, the special polyunsaturated fats found in fish and some other foods, have been reeling in a lot of good press lately for their role in heart disease prevention. They're vital for brain development, too, and have recently been linked to better cognitive function in older people. Plus, they may help treat rheumatoid arthritis and other autoimmune conditions. It's no wonder, then, that food manufacturers are looking for ways to add these healthy fats to spreads, breads, eggs, yogurts,…

1) Find resources outside the dome, other than the kelp which can help give you the nutrients that your body needs. 2) Conspire ways which can help purify the kelp; trial and error. 3) Eat the kelp and slowly watch yourself die, Kelp is a form of algae or seaweed that contains many vitamins such as vitamin B, C…

marshes and help them grow. They also help make air in the dirt. The destruction of fiddler crab colonies damages the places they live in. Fiddler crabs help the places they live in, just by living there. Fiddler crabs only eat small things, like algae, shrimp, plankton,…

Observations were made for a neighboring science teacher. Ms. C (whose name will remain confidential) teaches all marine ecology courses. A class typically filled with juniors and seniors. At the school, this is an elective course taken as a student’s final science requirement for graduation. Most of the students who enroll in the class do not wish to take the harder elective options such as an AP class, physics, or chemistry. I observed the teacher during her first block class while she was…

Introduction: Within this task we were required to determine the ecological state of the Reddam House wetland, which I presume is at a good standard. I decided to test the ecological status of the wetland by gathering samples from the wetland and testing it for various aspects in the water and the plants that are found within the area. Method: • Collected water in a sterilized bottle at Reddam House wetland as well as observed surrounding fauna and flora. • Took the water to Rand Water to have…

A niche is the role or part that an organism plays in it’s specific ecosystem or habitat. An example would be a sunflower. The sunflower inhabits a grassy area and the role that it plays in the area is that it is the producer that gives off energy to the other trophic levels that also inhabit the grassy area. (1) In total, I found 7 different kinds of bacteria in the columns. (2) -In the Controlled Column, I found Cyanobacteria (5) along the top of the column. This bacteria causes the lighter…
