3. History of the Wisconsin Fast Plant Dr. Williams wanted to make a faster growing plant. He wanted to make a plant that had to be under constant light and water. That took him over 20 years to breed the Wisconsin Fast Plant. The Wisconsin Fast Plant was a top hit to schools and classrooms because of how fast the plant grew. It grows to its adult size within 6 weeks.

4. Variable we tested (Manipulated) • The Variable we tested was space. We tested space because we wanted to see if the article about the plants was right. The article said ” The Wisconsin Fast Plants grow better in crowded areas .” We also wanted to see if they would grow better if more of the space was taken up. For the tested plants we put in 13 seeds in the 2 tested cells.

5. Variables Not Changed (Controlled) • The Variables we did not change were light, fertilizer, space, pollination, temperature , and water. For the controlled we put in 1 seed in each controlled cell.

6. How we tested the variable (Responding) We first got a little four cell box and put a blue wick through each opening at the bottom of the box. Next we put some soil about half way up to help keep the plant in place. Then we put in 13 Wisconsin Fast Plant seeds in each tested cell area. Next we were able to put a little more soil to cover up the seeds. Finally we had to water the plants. We watered the plants until the water dripped a bit at the bottom.

7. Graph of Plant Growth: Control Plants Most of the control plants grew in a steady matter. Except for Tianna’s control plants (which grew to 0 cm) most of the control plants were healthy until we had to extract the seeds (we had to dry out the plant). Paul’s plant cell #1 died on 11/15/13. That was the only control plant that died in the blue group. For these plants we gave them everything they need to survive. We have to give them water because if we didn’t the plants would dry up. We kept a light on for 24/7 for their light supply, without it they can’t photosynthesize. We made sure that the room temperature stayed at the correct level or else they would get to cold or get to warm. We gave them only 3 fertilizer pellets, if we gave more or less they would be weird looking. We only planted only 1 seed in both control plant cells (cells 1 & 2), if we planted more it would be over crowded. That is what the control plants are about, you keep all the variables the same. Paul’s plant grew the highest, starting at 2 ½ cm for cell 1 and starting at 1 cm for cell 2. Paul’s plants ended at 11 ½ cm for cell 1 and for cell 2, they ended at 19 cm. Tianna’s control plants only grew to a height of 0 cm, making hers the shortest control plants. This all took place in a manner of 1 month. We only recorded data for 8 days.

8. Graph of Plant Growth: Test Plants • The tested plants grew a lot in a period of 8 days. The first day it was able to grow 3 ½ cm. The second day it grew to 5 cm. The third day it was able to grow up to 9 cm . The fourth day it grew 1 cm higher which was 10 cm. on the fifth day our tested plant grew14 cm. This is a lot of plant growth in only 5 days. On the sixth day it grew up to 16 cm. The second to last day which is the seventh day it grew to 17 cm. Finally the last day it the plant grew to 19 cm.

9. Sketch of flowering Plant • The roots take up water(in H20 there is nutrience that the plant need's)and gives structural support to plants. • The stem carry’s H20 and sugar to leaves and the flower so that the plant can reproduce and create energy. • The leaf is what changes the suns power to a chemical process called photosynthesis. • Transporation is when water leaves as gasporation. • Flowers have reproductive parts of the plant that attract specific pollinators. For example, white flowers attract bats. And tube like flowers attract

10. Illustration of interdependence between flowering plants and bees • The way interdependence works is that the flower is able to make pollen. The bee needs to make the honey and to do that the bee has to collect the nectar from the anther of the flower. The flower depends on the bee to pollinate the plant so the plant is able to grow into a beautiful flower. The bee also depends on the plant to give it food. In the same way we depend on the bees to give us honey to eat.

11. Sketch of fertilized Plant • The parts of a brassica plant are the petals, anther , philoment, The anther and the philoment= the stamen, there is also the plant stigma, and the pollen grains. Some new structures are that the plant has leaves that grow over time onto the plants stem.’

12. Sketch of worker bee • The worker bee has eyes, a head , and abdomen , and a thorax. The bee also has hairy legs to collect pollen from flowers. The bee uses these legs to pollinate flowers. The bee also collect nectar from the flower for food. The bee goes to the hive to feed the queen the nectar it found in the flower. The worker bee works until she dies. The bee will also make honey with some of the nectar that the bee

13. Conclusion We put 13 seeds in the tested cell and put in 1 seed in each controlled cell. One difference between the tested and the controlled is that the controlled plant had turned a bit purple on the tips of the leaves and the stem and the tested stayed green the whole time. One comparison between the tested plants and controlled is that the tested plant grew more taller than the controlled plant because we put the tested plant in a group and we only put one plant in the controlled . We learned that the brassica plants grow more when the plants are in groups. We think this because it says in the article ” Wisconsin Fast Plants grow faster when they are in groups.” We also learned that the plant needs constant light and water to be able to keep growing until it shrivels up and dies. We had to do that to keep it alive until we were able to collect the plants seeds.
