• Ahora contesta las siguientes preguntas a medida que están construyendo el filtro de agua: - ¿El envase o recipiente utilizado será apropiada para la cantidad de agua que deseas filtrar en el tiempo que has determinado?

- ¿La cantidad de cada material utilizado en el filtro de agua será lo suficiente para retener las partículas sólidas del agua?

- Coloca primero los materiales de menor porcentaje de porosidad y luego los de mayor porcentaje ¿obtendrás los mismos resultados que colocarlos de manera invertida?

- Si, varía el espacio que ocupa un material dentro del filtrador ¿qué sucede con el tiempo de filtración?

- Si piensas, utilizar un recipiente de cerámica, ¿serán los mismos resultados que utilizar un envase de plástico?

- Si has incorporado un material de tu entorno, ¿cómo contribuye a mejorar la calidad del agua filtrada?

- ¿Qué problemas encuentras durante la construcción del filtrador de agua?

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.
