Agrowing mass of plastic garbage is collecting in an area of the pacific ocean. this is caused by plastic
garbage that is discarded by people, and it ends up in rivers that carry it to the ocean. over time, ocean
currents cause it to accumulate in this area of the pacific. currently, the mass is estimated to cover an area
of ocean twice the size of texas. as these plastics slowly break down, chemicals enter the water, and can
enter ocean organisms that we might eventually use for food. this sequence of events illustrates that
(1) humans modify ecosystems as a result of population growth, consumption, and technology
(2) human activities that degrade ecosystems result in an increase in diversity of ecosystems
(3) when humans alter ecosystems by adding specific organisms, serious consequences could result
(4) industrialization brings a reduced demand for fossil and nuclear fuels

98 points you will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. before you conduct your experiment, you need to form a hypothesis. a hypothesis is a prediction of what you think will happen in the experiment. the hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. record your hypothesis here: record the results from step one of the experiment (dropping the objects in the air): first trial: second trial: third trial: record the results from step two of the experiment (dropping the objects in a vacuum): first trial: second trial: third trial: did the experiment support your hypothesis? using the data from your experiment, describe why you believe your hypothesis was either proven or disproven. what forces were acting on the objects dropped in the air? what force was acting on the objects dropped in the vacuum? part two: comparing forces choose two forces and compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different. you may make a list, write in paragraph form, or make a chart. choose two forces and compare and contrast these forces. these must be different forces than used in the prior question. provide two ways that they are similar and two ways that they are different. you may make a list, write it out, or make a chart.
