The Nerds

Wed 5/18/05 10:03 AM - T7 (Julia): The first upload of our journal is complete.
Mon 5/23/2005 10:41 PM - Dr. B. Schulz: Hi: I have a few questions for you. How many seeds will each of you use for this experiment? I like the fact that you have established a control. How will you use the data from the control? You mentioned that vinegar will be used by a member of the team. Will you use the vinegar straight from the bottle or will you dilute it with regular water? Have you thought about maybe making several different concentrations of vinegar. Maybe you could have one where you use only 10 milliliters of vinegar in 100 milliliters of water. I will watch for your answers to these questions. Good luck with your experiments.
Thu 5/19/2005 9:53 AM - T7 (Hillary): Coca Cola- Hillary soaked her peas in coca cola for five minutes just like she does everyday. Nothing new happened to the peas and there was no sign of growth. Ashley commented on my peas and said "I don't think the seeds are going to grow in coca cola!" Hillary said "I regret picking coca cola as my liquid because nothing is happening at all." Callie said "I wish I would have done coca cola!"
Pink Lemonade- Callie has been watching her peas over the past few days and nothing in particular has happened except the sprouts keep getting longer and the transparent shells are falling off. Hillary commented on Callie's peas by saying that she thinks the peas are getting larger over the few days they have been soaking.
Water- Ashley has been watching her seeds in water. Lately a lot has been happening and her sprouts are growing extra long. They're turning a white color and they are growing in seed size. Where the sprouts are growing the seeds are starting to break apart.
Vinegar- Julia has been watching her seeds soak in vinegar. Lately nothing has grown at all. There are turning a light brown color and not growing a bit. Hillary commented on her seeds by saying that she thinks they are growing in seed size and the length of the sprout also.
Thu 5/20/2005 9:53 AM - T7 (Hillary): Coca Cola- Hillary hasn't seen anything big happening to her seeds at all. Callie commented on her seeds by saying that she thinks they are dead. Hillary agreed. The Peas shriveling up and not sprouting or growing at all!
Pink Lemonade- Callie's peas are growing and changing color. They may not be growing very much but it's definitely a change in size. The color has changed from a light green to a brownish color.
Water- Ashley's seeds haven't changed color. They have grown a big lot since even yesterday. The sprouts keep getting longer and greener. The shells get farther and farther apart as the seeds grow.
Vinegar- Julia's seeds haven't done anything since yesterday. They look the complete same except the color is changing from a light brown to a dark brown. Hillary commented on her seeds by saying she thinks that the color is changing because of the color of vinegar. Hillary also said that she thinks that if Julia had been using vinegar that was like a pink or another color it would change to that color.
Sat, 5/28/05 12:52 PM - Dr. S. Singer : I enjoyed following your journal entries this week. Your seeds are getting bigger because the are imbibing water. Plant cells have some unique properties that allow them to take up huge amounts of water and increase in size. If the seeds are taking up water, do you think they could be taking up other substances in your solutions? Susan
Sun 5/29/05 4:30 PM - Dr. S. Singer : Your journal entries include some thorough descriptions of the changes you observed in the peas. Such keen observation skills are highly valued by scientists. Good luck with your future experiments. Susan
