The speech that will be critiqued is called‚ “A Drop in a Plastic Ocean: How One Person Can Make a Difference.” The speaker is Emily De Sousa‚ an environmental activist. It was obvious from the beginning as to why she decided to speak in front of the audience‚ to persuade them. More specifically‚ it was a speech to actuate. De Sousa wanted people to agree with her that plastic pollution is a problem in the world’s oceans and get them to take action to better protect marine life’s environment. She

The Observation of organism in a drop of pond water (Paramecium) under LPO and HPO Compound Microscope Doreenda A. Sabao BS Biology I-A .Lab 1 August 01‚ 2013 INTODUCTION A pond is a body of freshwater smaller than a lake. Ponds are naturally formed by a depression in the ground filling and retaining water. Streams or spring water is usually fed into these bodies. They can also be man-made ponds which can be created by damming a stream‚ digging a hole. Ponds are usually

tubes and label each with the numbers 1‚ 2‚ and 3 with a glass-marking pen (preferably on a piece of masking tape) and place them in a test tube rack. Add a 0.5 cm cube of Beef liver into each tube (if not already prepared‚ use a scalpel or knife to cut your own pieces). Using a medicine dropper‚ add 3-4 drops of pH solution 2 for test tube 1‚ pH 7 for test tube 2‚ and pH 11 for test tube 3. Add a few drops of tap water for each tube. Then‚ add 2-3 drops of hydrogen peroxide for each tube and wait

amount of drops that can fit on a penny. I used 3 liquids to test my question and they were water‚ rubbing alcohol‚ and vegetable oil. I discovered that water could hold the most drops and vegetable oil and rubbing alcohol could hold about the same amount of drops. My hypothesis was if I use water then it will hold more drops than vegetable oil. My hypothesis was supported by my data. The average number of drops for water was 93 whereas the average for vegetable oil was only 36. Obviously water held more

Have you ever dropped oil on your hands and tried to wash it off? What happens? Does the water slide off? Or what about when a drop of oil falls in a glass of water? Why does it float to the surface‚ and not mix? The answer to this is simple: polarity. What exactly is polarity? A polar bond is when there is a difference in electronegativity‚ which means the tendency of an atom to attract a bonding pair of electrons. When two atoms are bonded together and one attracts more electrons‚ this results

For example if the ball is dropped into water‚ its energy will affect the water‚ causing some amount to splashed out. When the ball is released from a height‚ its initial potential energy combined with the gravitational energy form a kinetic energy‚ which transmitted to the water. So I will investigate the relationship of drop height of the ball and the amount of water splashed out. Research question: How does the volume of water splashed out depend on drop height of the ball? Explanation for controlled

not be argued that higher temperature causes more evaporation from the ocean surface‚ which‚ in turn‚ results in higher salinity content? Figure 9.4 shows how the surface temperature of the ocean and the surface salinity change with latitudinal position. Salinity the measure of the concentration of dissolved salts in the ocean water. Salinity influences where plants and animals can thrive‚ and also affects aspects of water quality and treatment. The measure of salinity directly correlates with

The Egg-Drop Device Process The process of dropping an egg is more complex than a normal person would believe. The egg-dropping process requires knowledge of history‚ engineering‚ and mathematics and physics. To fully understand how an egg drops‚ the knowledge of the history of physics‚ the engineering behind a device‚ and the mathematics and physics of free-fall is needed. Classic physics originates in Ancient Greece. The theories Thales‚ the first physicist‚ designs gives the discipline of physics

“Ego”. To describe this word‚ most people would say it is the word that means‚ “I”. It is the word that makes each person individual. Ayn Rand writes a story called Anthem bringing to life a character named Equality 7-2521 along with his companion Liberty 5-3000. The society they live in believes every person should be equal. “And we know well that there is no transgression blacker than to do or think alone” written in Anthem. In this story‚ there is no such thing as the word “Ego”. But to Equality

Plastic in the Ocean More than 200 animal species are dying everyday because they are consuming plastic in the ocean. This paper will discuss the environmental issue of polluted oceans‚ the causes‚ and possible solutions. The current environmental issue is littering in the ocean. Everyday hundreds‚ thousands‚ and even millions of trash is dumped into the ocean. Hundreds of marine species eat large amounts of plastic debris. “Yet the question is why so many species from the tiniest zooplankton to
