How Experiment was How Experiment was ConductedConducted

The first thing that was done was wicks were put on the The first thing that was done was wicks were put on the bottom of each cell. Then fertilizer pellets and seeds were bottom of each cell. Then fertilizer pellets and seeds were put in and covered with more soil . The seeds were then put in and covered with more soil . The seeds were then put on the watering system. In the experimental quad the put on the watering system. In the experimental quad the seeds were placed in the center of the cell, and on the seeds were placed in the center of the cell, and on the others the seeds were placed on the bottom of the cell. others the seeds were placed on the bottom of the cell.

The plants were observed every day in class . On day The plants were observed every day in class . On day thirteen, The plants heights were measured height in mm. thirteen, The plants heights were measured height in mm. On day 21 the plants were pollinated with bees on sticks .On day 21 the plants were pollinated with bees on sticks .

Finally on day 28 the plants were harvested. They were Finally on day 28 the plants were harvested. They were harvested by taking off the pods and taking out the seeds harvested by taking off the pods and taking out the seeds from each pod.from each pod.

Conclusions Conclusions

Wisconsin fast plants need to have Wisconsin fast plants need to have water 24 hours a day water 24 hours a day

They also need light 24 hours a They also need light 24 hours a dayday

Seeds grow taller when planted in Seeds grow taller when planted in the center of the cell not the the center of the cell not the bottom or the top of the soilbottom or the top of the soil
