I. Warmup Questions
1. Coffee beans are crushed into small pieces, water is added to it and the mixture is heated over a flame. What do you think would happen to the coffee bean as it interacts with the water? Explain.
Essentially the warm water will run through the coffee beans and extract its properties. The flavor of the coffee beans would disperse into the water. The water would change color and smell like the coffee beans as these properties are drained from the coffee beans.
2. What would happen to the water if instead of coffee beans, strips

Procedure
1. Weigh five grams seaweed. 2. Wash the seaweed to get rid of Monosodium Glutamate 3. Boil the seaweed in 40 ml water for 5 minutes 4. Filter the seaweed and collect about 3 ml solution 5. Pour the solution to a clean beaker, then add 3 crystals of iodine 6. After 10 minutes, conduct the observation test V. Observations of all tests Standards
Iodine Test Light Purple
Iodide Test Yellowish milky white, some precipitate
Triiodide Test Brownish
To begin the experiment first obtain the required safety goggles and equipment. Part one of the experiment begins with calibrating the pH meter using buffer solutions of 7 pH and 4 pH. The pH measurement should be 0.10. After the use and calibrating the pH meter rinse the electrode using distilled
This lesson caters to the needs of the students in our class because they decided on the topic of interest that they wanted to learn. It is also grounded on current pedagogy and ties to BC’s New Curriculum. By learning about the different types of dwellings the Coast Salish people built and inhabited, students will be able to recognize the challenges the environment conditions would have had on their living situations and become more educated on the people who inhabited their land before them. Through the process of brainstorming, students will bring their previous knowledge and experiences about Coast Salish dwellings and compare it to the information given in class. By writing a paragraph from the perspective of a Coast Salish person, students will be able to demonstrate their understanding of the challenges this First Nation group had in regards to their living situation. They will also explore different types of writing such as first person, narrative, and explore different points of view. By illustrating their paragraph with a drawing, they can demonstrate their understanding of the topic in a visual way.
Plants come in different shapes, colors and sizes. Redwood trees, found in California, are the tallest plants on Earth. The tallest redwood ever recorded was 379 feet tall in 2006. The smallest flowering plants in the world are watermeal, also called duckweed. They can be found all over the world and are as tiny as a grain of rice.
Johnson’s Seagrass is an asexully reproducing species of fragile seagrass. Due to this, the range of Johnson’s Seagrass is limited to a length of 200 km of river mouths off the coast of Eastern Florida, giving it the prestige of being the seagrass with the smallest distribution, measured in hectares, in the world. The seagrass leaves are about 2-5 centimeters in length. This seagrass is tolerant of varying salinity but is not tolerant of damage caused by human boating activities and actions including anchoring boats and dredging waterways. This species of seagrass is so easily disturbed that it is uprooted by the turbidity caused by boat propellers. Halophila Johnsonii is also threatened by water that has been tainted by environmental pollutants.
The Sea Lamprey (Petromyzon marinus) is an eel-shaped fish with a skeleton made of cartilage, not bone. Lamprey typically grow up to 30cm in length, weighing up to 2.5kg. Their coloring varies from brown, gray, or black on its back and white and gray on their underside. They are easily identified by their wide circular sucker mouth that is filled with numerous small teeth. The lamprey use their mouth, to attach themselves to a wide variety of fish, in which they feed from. Lamprey do not have any paired fins, but they have both a dorsal and ventral fin. They are also, scaleless, have a pair of functional eyes, and seven gill openings.
Although I am no longer pouring beverages, I still find excitement in educating others about their coffee habits. In fact, my favorite thing about coffee is how complex and versatile the beverage can be. Many individuals carry on their normal routines drinking cup after cup of coffee, without knowing much about the beverage other than it carries a jolt of energy. Today, I get to share with you one of my favorite pass times: Educating the average coffee consumer and transforming them into a coffee connoisseur. From the training I received and my personal experience, I believe to become a coffee connoisseur, one ought to be knowledgeable in four essential areas of the coffee bean. A true connoisseur will understand the history and origin of coffee, the different growing regions and their affects, how to brew the perfect cup, and the chemistry behind the bitter beverage. The first crucial area of coffee knowledge is to understand the roots of coffee. So, we begin with a little a legend.
Firstly, in each of the boiling tubes place 8 ml of 2% starch solution using the syringe. Then in each of the test
For twice a day, the tides near the coast rises and falls. The tide lets distinctive ecosystems to exist in one particular environment, such as the salt marshes. Salt marshes are formed in shallow areas between islands joined to the mainlands. The marsh is a strict environment for wildlife to survive in. The temperature can rapidly alter with the fluctuating tides in the day (Boesch et al. 1984). The varying influx of salt water yields the land to have constant changing exposure to salt water and air. It is difficult for species to populate the salt marsh throughout the year. Numerous land and aquatic species visit the salt marshes to feed and find protection and the due the shallowness of the waters, the marsh can protect some marine species before returning to the ocean (Wu et al. 2009).
Each test tube will receive 2mL of saliva and mix. Test tube one goes into the ice-water bath, two goes into a 35-40*c bath, and the third into boiling water. The test tubes need to stand in their water baths for 30 minutes, at least. After the 30 minutes we transfer 3 drops of each solution into separate depressions of a white spot plate. Each sample will receive 2 drops of iodine solution. We observe the colors, and record our results.
It is not a rare scene when you come to the office and see your colleagues are sipping their cups of coffee. As a matter of fact, coffee has now become a common type of drink for many people, especially office workers. Not only my family use daily drink but also most people in the world love it. That's why I'm excited about it and I decide to select it for my research paper. I haven't enough experience and knowledge, so I do by summing material from books, articles and information from reliable sources on the Internet. My paper will answer three questions:
First, a lesser amount of water is used than in the brewing process of a traditional cup of coffee. In addition, rather than simply using hot water, the water used to brew espresso is extremely hot, often near the boiling point. This near boiling water is put under a large amount of pressure and pressed against the beans. These beans are also packed down tight into a pod. While an average cup of coffee uses coarse beans, beans used for espresso are very finely ground to encourage a more concentrated final
The adiabatic filter will not increase or decrease in temperature and so the coffee brewed will have no change in terms of taste. Adiabatic process is applied
Temporary plots are established for the purpose of above ground pool and soil carbon measurements. The objects are for a single measurement of forest composition, structure and carbon pools. In this study, a sampling design was adopted from Kauffman and Donato(2012)/Murdiyarso et al(2009) to describe composition, biomass and ecosystem carbon pools. To assess the carbon stocks, mangrove ecosystems were divided into two parts; above-ground and below-ground components. In each sampled forest ecosystem, a transect arranged perpendicular from the river or coast shoreline was established with no a priori knowledge of forest composition or structure. Six plots were established along the transects at
The piece of art that I chose is called Seascape created by Elizabeth Meyer. She became a resident of the Monterey Peninsula which made her passionate to paint, due to the beautiful scenery she was surrounded by everyday. She has many peaceful and majestic paintings that make you feel so relaxed. She said that she has taught herself how to paint and that she paints straight from her heart. Her artwork is abled to be viewed in Monterey, Pacific Grove, and Carmel. When I viewed the art gallery I saw many fascinating pieces of artwork that all contained the compositional elements. The gallery was in a small house made of wood. In the gallery there were a variety of different paintings, but what made Elizabeth Meyer’s stand out was that all of her artwork was framed in a beautiful and eye catching shimmering gold frame. The way her art was displayed made me drawn to her art individual. All of her art made me feel a sense of peace and ease. Elizabeth Meyers art was altogether astonishing. While all her artwork was unique and original, her work that stood out to me the most was her painting “Seascape”.
Coffee beans need to be roasted to bring out their irresistible flavor and aromatics. The sooner a roasted bean gets into a cup, the better the flavor.
