Research Page for Pershing County High School, Team 3

4/20/05 12:15PM - T3: Our research question is: Is the size of the seed comparable to the size of sprout?
4/25/05 10:51AM - Dr. Claire Hemingway: Seeds vary enormously in size: from the dust-like seeds of orchids to the massive, 30 kg seeds of the double-coconut plant. How variable is the size of seeds in your sample? What pattern to you expect to see in sprout size?
4/28/05 12:39PM - T3(tony): Our seed's sizes range from 2mm to 1 cm. The biggest seed we believe will have the longest sprout while the smaller seeds will have the least measure of sprout. With soy being our biggest seed our predictions are that the sprouts will reach a length of 12 cm, till the first true leaves appear. Red clover, our smallest seed we predict will reach a length of 5 cm, until the first true leaves appear.
4/30/05 11:58AM - Dr. Beverly Brown: Team 3 you have a great question.  What data are you planning to collect so that you can reach a conclusion?  What species will you be using?
5/6/05 2:21PM - PEER COMMENT from Pershing Team 4: Well hi Team 3 this is team 4 i was just wondering how ur sunflower seeds are doing mine are doing well.
5/10/05 12:15PM - T3(Kala): We have upoaded our Background and Research page, with our questions, observations, and research template. Our data that we plan to collect is overall sprout length with every seed through out the length of our experiment. Our species vary and include millet, wheat, soy, red clover, rye, and alfafla.
5/10/05 1:39PM - T3 Response to Pershing County High School Team 4 (Kala): Sorry Team 4 but we don't have any sunflowers in our group.
5/14/05 11:07AM - Dr. Jenny Archibald:It looks like you’ve measured just one seed/sprout per seed type.  Is that true, or are those mean values?  Does there appear to be a lot of variation in seed and sprout size within a given species?      
There are often many different ways that we can show our results – and how you show your data can make a big difference in how easy they are to interpret. One method you might consider is graphing sprout length vs. seed length, rather than sprout length vs. seed type.  You would end up with just one line and could then look at the slope of the line and see if the results even fit a line (that is, is there a direct increase in sprout length with seed length, as you predicted).
