Our results are as follows:Stem#1 Segment Measurement 1+2 avg. .7cm3 .4cm4 .3cm5 .2cm6 .2cm7 .2cm8 .2cm9 .2cm10 .2cmStem#2 Segment Measurement 1+2 avg. .8cm3 .5cm4 .3cm5 .3cm6 .2cm7 .2cm8 .2cm9 .2cm10 .2cmStem#3 Segment Measurement 1+2 avg. .7cm3 .5cm4 .5cm5 .3cm6 .2cm7 .2cm8 .2cm9 .2cm10 .2cmStem#4 Segment Measurement 1+2 avg. .6cm3 .3cm4 .3cm5 .2cm6 .2cm7 .2cm8 .2cm9 .2cm10 .2cmStem#5 Segment Measurement 1+2 avg. .9cm3 .7cm4 .4cm5 .3cm6 .2cm7 .2cm8 .2cm9 .2cm10 .2cmStem#6 Segment Measurement 1+2 avg. .7cm3 .4cm4 .4cm5 .3cm6 .3cm7 .2cm8 .2cm9 .2cm10 .2cmDiscussion:The growth of the leaves was about what we had expected it to be. It was tough to get the plants to grow, probably due to the cold draft from the window. This began to slow us down and we ran short on time. The plants that were grown from the environmental classes had to be used. Before Christmas vacation, seeds were placed in petri dishes with wet paper towels. By the time we came back we could tell that the seeds had sprouted, but had died from lack of water. It was determined that we would quickly have to perform this experiment at Mr. Kihm s private laboratory. After these measurements were taken we could see that we had guessed right in that the most growth would occur at the tip of the roots. For the stem measurements we had to grow our own again at Kihm s Science Museum. It came to be determined that the average measurement for the stems was 2.83cm. The stem results were on target with what we expected. Conclusion:Right from the very beginning of this lab we were plagued with problems. From plants not growing at all, to one s that did and died we almost deserved a purple heart for getting this one done. As stated before, we overcame these problems by working at Kihm s house. From our readings, we were able to accurately guess where the most growth would take place in the roots, leaves, and stems. The most notable facts that we learned were that plants do not mature like animals do, they are continually growing, and that only certain parts of these plants do the growing.
