Date completed: May 12th
Hypothesis: I believe the seeds will grow 1-2 feet based on my research
Procedure: I put my seeds in small pots and put on a self I have outside in the sun. They can absorb good sunlight this way
Growth of seeds: all varied but stayed within 3 feet
Type of seeds:
1. Cornflowers
Growth
Day 3: about 2 inches
Day 6: about 5 inches
Day 9: about 12 inches
Day 12: about 22 inches
Day 15: about 34 inches
Interpretations: cornflower- the meaning is wealth, prosperity, fortune and friendship.
I don’t know what was asked in the lab...
Conclusion: my hypothesis was kind of correct. My cornflowers grew to be over 2 feet, but not by much. Some even stayed under, but not by much I say again. This was a fun and educational experience and I learned a lot about this wonderful plant. I hade no idea that it was even a real thing before this project! I learned that different flowers grow at different paces, even if they get the same amount of sunlight and water.
