Question: Alice planted one radish seed in each of 5 separate pots (Pot one, Pot 2, Pot 3, Pot 4 and Pot 5). She used the same amount and the same kind of soil in each pot. She put them by the same window. The first graph shows the amount of water she put into each pot every day (Pot one got 5 milliliters, Pot 2 got 10 milliliters, Pot 3 got 15 milliliters, Pot 4 got 20 milliliters, and Pot 5 got 25 milliliters). The second graph shows the length of each root after 7 days (0 centimeters for Pot one, 4 centimeters for Pot 2, 8 centimeters for Pot 3, 5 centimeters for Pot 4, and 0 centimeters for Pot 5). What is the range of tolerance for water for these radish seeds? Explain how you decided the range of tolerance.
Reference answer: 10 milliliters to 20 milliliters. The radishes did not grow at all in pots one and 5 so the range of tolerance is for pots 2, 3 and 4, which got 10 to 20 milliliters of water.

Student answer: 0 to 25 milliliters, 0 to 25 milliliters because the plants all grew from 0 to 25 milliliters of water.

Student answer: 10 to 20 milliliters of water. Pot 2, 3, and 4 had been watered between 10 and 20 milliliters of water and they were the only ones that grew.

Student answer: 10 to 20 milliliters water, I looked at which plant roots grew.

Student answer: 10 to 20 milliliters of water, none grew in one or 5 so those do not count for range of tolerance.

Student answer: 10 to 20 milliliters, Well in pot one nothing grew same in pot 5 so the one that grew are a range of tolerance form 10 milliliters to 20 milliliters.

Student answer: 10 milliliters to 20 milliliters, on chart 2 pot 2, 3, and 4 grew and one and 5 did not, on chart one pot 2 was given 10 milliliters, pot 3 15 milliliters, and pot 4 20 milliliters.

Student answer: 10 to 20 milliliters, How I found the range of tolerance was I looked at which roots grew and found 10 to 20 only grew.

Student answer: 15 milliliters of water, looking at the graphs.

Student answer: 5, because some grew but not many so that is why I choose it.

Student answer: 5 to 25 milliliters, Because the chart says they only give them 5 milliliters to 25 milliliters.

Student answer: 10 to 20 milliliters, Because 10 to 20 milliliters of water is when they started to grow and when the root stopped.

Student answer: 25, I remembered the observations of Alice and put them in the questions to help me answer the questions.

Student answer: 20 milliliters, Because the most water is 25 milliliters and in column 5 nothing grew. So I went to the next column which is 20 milliliters, and something grew.

Student answer: 20 milliliters, The last number 4 and everyday she used 20 milliliters.

Student answer: 5, Because they can still live in that amount of water.

Student answer: 25 milliliters, I looked at the graph.

Student answer: 3, Because, it is the most and the highest one the for it.

Student answer: 10 to 20 milliliters, I looked at the root length and only 3 had lengths. The lowest was low and the highest was 20.

Student answer: 60 milliliters, How I decided I add up all the numbers of the graph.

Student answer: 25 milliliters, The highest water bar.

Student answer: 15 milliliters, Because pot 3 grew the best with 15 milliliters.

Student answer: 10 to 20 milliliters In the second graph, pot 2, 3, and 4 actually grew. In the first graph, pot 2, 3, and 4 had water between 10 to 20 milliliters.

Student answer: It should be 10 because it grew 9 inches and it had.

Student answer: 10 milliliters, Because it starts growing at 10 milliliters.

Student answer: 10 to 20, I decided those numbers because those are the ones that actually had roots and were growing.

Student answer: 10 to 15, I decided because they almost look the same.

Student answer: 3, because if there a good amount of water it will work.

Student answer: 20, I subtracted the highest amount of water by the least and it seemed to be that much.

Student answer: 25 water milliliters, the root of the graph 4 inches, 5 inches, 8 inches.

Student answer: The same, because they all sat next to the same window.

Student answer: 10 to 20 milliliters, Because I saw that 2 to 4 on the roots graph where the only one that grow. So 2 to 4 on the water graph have good amounts.

Student answer: 10 milliliters to 20 milliliters, Because if you put that amount plants will grow but if you put the other amounts you get no plants.

Student answer: 3 centimeters, because it is the tallest root length and the plants will be taller.

Student answer: 2 to 4 milliliters, Because on the chart 2 to 4 was the only one that barely grew.

Student answer: 10 to 20 milliliters of water, pot 2 got 10 milliliters and grew roots and 15 milliliters for pot 3 and it grew roots and pot 4 had 20 milliliters and grew roots. The first pot did not have enough milliliters and the last one had too much milliliters.

Student answer: 4, 4 because there is less seeds but it would grow more.

Student answer: 10 milliliters to 20 milliliters, because then plants only grew in 10, 15, and 20 milliliters and they were able to tolerate it.

Student answer: 10 to 20 milliliters, because the second graph tells me the roots only grow in pots 2, 3, and 4. The water from pot 2, 3, and 4 is from 10 to 20 milliliters so I think it is the best range of tolerance.

Student answer: 25 milliliters, Because 25 milliliters of water is too much water for radish seeds. The seeds could get soaked and die because of too much water.

Student answer: 6 centimeters to 22 centimeters, Because when she put 5 milliliters of water no plants grew. And when she put in 25 milliliters of water no plants grew. So it is no lower 5 milliliters and no higher than 25 milliliters.

Student answer: 10 milliliters to 20 milliliters, Look at the amounts that made the plants grow.

Student answer: 10 milliliters to 20 milliliters, because on the graph it show that the root grew on 2, 3, and 4, So I look at how much water was given and wrote 10 milliliters to 20 milliliters.

Student answer: 15 milliliters, pot 3 had the longest roots then the others so I compared the 2 graphs and got 15 milliliters.

Student answer: 10 to 15 milliliters, That is the right amount because in the graph the second largest was watered with 10 milliliters of water and is not too much or too little.

Student answer: 15 to 20 milliliters, I if you subtract 5 milliliters from 25 milliliters you get 20 milliliters and I get 15 milliliters as the optimum amount of water so I put 15 milliliters to 20 milliliters.

Student answer: 10 to 15, Well, if you go past 15 that will be too much and if you go below 10 that will be too little so it is just right. So it will be around 12, 13, 14, or 15.

Student answer: 10 to 20, I decided that because those are the numbers that had long roots.

Student answer: 10 milliliters to 20 milliliters, those were the plants with roots.

Student answer: 20 milliliters, Range mean biggest number and lowest number subtracted by.

Student answer: 10 to 20 milliliters, Because those are the distances of which the plants grow in.

Student answer: 20 milliliters, Because after 20 milliliters the seeds roots were 0 centimeters.

Student answer: 20 milliliters, To find the range you have got to take the lowest amount of water and subtract that from the highest amount of water. If the highest amount is 25 milliliters and the lowest is 5 milliliters you have got to do 25 minus 5 equals 20 milliliters. So 20 milliliters is the range.

Student answer: 10 to 20 milliliters to 10 to 20 milliliters is the amount of water needed to help the radish seeds roots to grow.

Student answer: 5, Because 5 milliliters makes the plant grow much bigger and faster.

Student answer: 15, Because when I matched the charts, I found out that pot 2 had the longest roots for only 15 milliliters. Even though pot 5 had the most water some of it roots did not grow.

Student answer: 10 milliliters to 20 milliliters, because the plants that were inside that range all grew.

Student answer: 5 to 25, The same way I decided the optimum amount.

Student answer: 20 milliliters, I decided 20 milliliters because I took 75 milliliters subtract 5 milliliters in the first graph.

Student answer: 15 milliliters, because the length of the root of pot 3 was he largest.

Student answer: 15 milliliters, It grows the longest roots.

Student answer: 10 to 20 milliliters, The graph that has the root length has only numbers 2, 3, and 4 that have roots, comparing it to the first graph, I got 10 to 20 milliliters of water.

Student answer: 15 to 20 milliliters, Once again I used the charts to get this answer.

Student answer: West one to 5, They have first and last one, they have most difference and I think the wet environment is the best, also the 15 milliliters water is the best.

Student answer: 15 milliliters, I decide the third pot which had 15 milliliters of water because the root was 8 centimeters. The one which is the highest.

Student answer: 10 milliliters to 20 milliliters, because it grew in pots 2, 3, and 4 which had from 10 milliliters to 20 milliliters and they were the only pots that had growth.

Student answer: 10 to 20 milliliters, I compared the growth to the water from the charts given.

Student answer: 10 to 20 milliliters, The range of tolerance is the range that the plant can grow and the plants grew with this amount of water.

Student answer: 3 pots, Because it is the best one out of them all.

Student answer: 3, because on the scale it was the third smallest and then grew the tallest.

Student answer: 3, The 15 milliliters of water for the third pot is the highest.

Student answer: 8, The range of tolerance was 9 because the radish plant grew big, 8 centimeters.

Student answer: Pot 3, because do not need that much of water or need that little of water.

Student answer: I did not know so I just put 5.

Student answer: 15 milliliters, I think it is 15 milliliters because the bar graph showed it was the highest.

Student answer: 20, I looked at the graph.

Student answer: 3, 3 because it took 3 days for it to grow 8 centimeters and 8 centimeters is the limit on the graph.

Student answer: 50 milliliters, because that is how much we put in.

Student answer: 10 milliliters to 20 milliliters, from looking at the chart I saw that pot 2 and 4 was around 3.

Student answer: 0 to 15, I looked at the chart and It said that pot 3 got 15 milliliters and on the bottom chart pot 3 grew the best.

Student answer: 45 centimeters, I add up the root length and the water together and got 45 centimeters.

Student answer: 10 milliliters, I saw the plant that grew the least and checked the water amount.

Student answer: 5 to 25 milliliters of water.

Student answer: No, because in one pot did not grow and the fifth did not grow too that why I said no.

Student answer: 5, I think the range is 5 because it is right in the middle of 4 and 6.

Student answer: 15 to 20 milliliters, look at the graph.

Student answer: 10 milliliters to 20 milliliters. Because pot 2, 3, and 4 have the longest roots and if you look at how much water they give it, it would be 10 milliliters to 20 milliliters.

Student answer: 33 milliliters, Because all together it is 33, 25 plus 8 equals 33.

Student answer: 10 milliliters to 20 milliliters of water. On the root graph pot 2, 3 and 4 were the only ones that had root so I looked at the other graph and looked at the same pot number and then looked at the water amount.

Student answer: In the water, because the radish must be grown in 25 milliliters.

Student answer: 25 milliliters, It is the biggest amount of water the plants drink in the top graph.

Student answer: 10 milliliters to 20 milliliters, I looked at which roots actually grew and then looked at how much water they got.

Student answer: Adding in 5, Because he is adding 5 because one pot is 5 pot 2 is 10 and on.

Student answer: 5 milliliters, By looking at the graph it is going by 5 milliliters.

Student answer: 10 to 20 milliliters. Since pot 2, 3, and 4 grew roots, I assumed the amount of water in pot 2, 3 and 4 would be best.

Student answer: 10 to 20 milliliters. Pots 2, 3, and 4 all grew and pot 2 had 10 milliliters and pot 4 had 20.

Student answer: 20 milliliters, The least number that was used and subtract it with the highest number that was used.

Student answer: One to 07 milliliters, because you could kill your plant.

Student answer: 0 to 25 milliliters, because it was 0 all the way up to the number on the chart which was 25.

Student answer: 10 to 20 milliliters, I looked at the roots that has grown than looked at the plants to go with it.

Student answer: 15 milliliters, because 3 was 15 milliliters.
