GOAT SONG ANALYSIS

What is poetry? More importantly, what is music? In this slideshow, we had to analyze our favorite song, and I picked "RATHER LIE" by Playboi Carti and The Weeknd.

Properties of Water Lab

This was a lab we did to demonstrate properties of water, particularly the colored water celery experiment(capillary action, which is cohesion and adhesion) and the magic milk experiment(surface tension). The colored water travels up the stem of the celery, even though it has been cut, and after time the outer extremities turn the color of the water. With the magic milk experiment, when you drop soap in the milk it disperses the dye along the surface of the water.

Properties of Water Posters

Solvency

Solvency is the property of water that allows it to dissolve many things. Water's electronegativity allows it to break hydrogen bonds of solutes.

Specific Heat

High specific heat is another property of water that makes it pivotal to life. Water needs a high amount of heat energy to change temperature, which allows large bodies to maintain their temperature and be habitable for aquatic animals, along with causing sweat.

Surface Tension

Surface tension is another property of water that allows for the surface of water to be flat. This allows for light animals to float across the surface of water, and allows seeds to travel on the surface, increasing the spread of plants.

Cohesion and Adhesion

Cohesion and adhesion are properties of water that allow it to remain bonded to both itself and other substances. Cohesion allows for surface tension, sweat, and plants to transmit water from the roots, and adhesion also allows for water transmit, the reason water forms concave meniscuses in glasses, and the reason water spreads on flat surfaces.

Macromolecules Lab

In this lab, we did 4 experiments to test 6 subjects for macromolecules(water, apple juice, oatmeal, oil, milk, and an unknown liquid(Sprite)). These experiments included drops onto paper to test for an oil stain, which indicates lipids, or putting solutions into these liquids and looking for color changes to find the other 3 macromolecules.

Carbohydrates

Carbohydrates are made of sugars (monosaccharides), and they are the body’s main source of quick energy. They also provide structural support in plants (cellulose) and in some animals (chitin).

Lipids

Lipids include fats, oils, and steroids, and they are used for long-term energy storage, insulation, and cushioning organs. They also make up cell membranes through phospholipids, which control what enters and exits the cell.

Nucleic Acid

DNA and RNA are nucleic acids made of nucleotides that store and transmit genetic information. DNA provides the instructions for building proteins, while RNA helps carry out those instructions in the cell.

Proteins

Proteins are built from amino acids and are the most diverse macromolecules, responsible for structure, movement, transport, signaling, and defense. Enzymes, a type of protein, speed up chemical reactions that keep cells alive
