Ms. Copeland's students built this model of an aquifer. Once built they added water and then on the top of the "hill" poured a small amount of used black motor oil simulate chemical pollution. They waited an hour and then used a long eye-dropper to remove some water from their well (the straw). The water did not contain the motor oil (pollution) but the students noticed that the oil was covering most of the pebbles in their model. Ms. Copeland asked her students to devise a method to remove the oil from the aquifer. What solution would you predict to be the most reasonable plan?

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
