A group of 4 students want to design an experiment in an effort to support the hypothesis, “Sunlight is needed for the normal healthy growth of plants.” Each student presented a possible experiment. Student #1: Purchase 20 plants. Plant 10 of the plants in 3 cups of soil and place all of the cups in the sun. Take the other 10 plants and put them in 2 cups of soil, then place this group in the sun under a box. Observe and document changes. Student #2: Place 10 plants outside in the sunlight. Place the other 10 plants outside under a box. Plant both in the same amount of soil and provide all with the same amount of water. Document observations. Student #3: Place 20 plants in front of a window. Give all of the plants the same amount of water and the same type of soil. Observe plants for any changes. Student #4: Obtain two seeds. Place one seed outside and one on an inside window sill. Observe and document which seed sprouts the fastest. Which student provides the best reason for choosing his or her experiment to test the hypothesis?

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
