Lost supplies for this and not enough time before due date to start now takes 7 days of observation, does anyone have this data? I need all observations, length and percentage of seeds for each solution germinated FOR EACH DAY!

PLEASE HELP!

Materials Water* 3 Petri dishes, Vinegar solution, Ruler, Radish seeds, Sodium bicarbonate solution, Paper towel sheets (cut to fit into petri dish), pH paper

Procedure

1. Obtain your petri dishes and label them, one for each solution

2. Cut out the paper towel to fit inside the petri dish. Wet each individual towel with its determined solution (vinegar, sodium bicarbonate, or water).

3. Test pH of three solutions and the paper towels containing the solution, record your values. 4. Arrange 10 radish seeds on each paper towel in each petri dish. Make sure the seeds have space and are not touching.

5. Place the petri dishes in a sunny or well lit warm place. You must be sure to keep the paper towels moist for the length of the lab with the appropriate solution and make sure that the solutions re%u2010 main at the same relative pH.

6. Observe seeds daily for 7 days and record the number of seeds that germinate (note when the seed cracks and roots or shoots emerge from the seed). Note: During this observation period, take pictures to document the radish seed growth. This can be done in a number of ways (example, mobile phone, camera, webcam, etc.). Images can then be scanned , uploaded via USB/cable connection, etc. onto a computer and be integrated into your final document.

7. On the 7th day record the lengths of radish seed sprouts. Compare and graph sprout lengths below. Don%u2019t forget to title your graph and label the axes.

*You will need to expand on the table below to record your observations and results for all 7 days.
