Seed Lab Report Essays Seed Lab Report Essay Seed Lab Report Essay The pH level of something is its measure of acidity or how basic it is, solutions with a pH of less than 7 are said to be acidic, and solutions with a pH greater than 7 are said to be basic. The tap water that was used to water our beans had a pH of 6. In this lab, we studied the process of germination (the process by which a plant grows from a seed). Certain environmental factors can cause or stop a seeds germination, and these factors include, but are not limited to, the mount of water, the amount of oxygen, the temperature or the amount of light the seed gets. There are steps that vary in germination, what first happens is the seeds radical comes out and then the roots also come out. The next step is the embryonic shoot that includes the seed leaves. The rate of germination depends on the species of plant being grown and its environmental factors. In the experiment, students studied the germination of blue lake bush beans in different pH levels including pH 5, pH 6 (tap water), and pH 8. They recorded the germination percentages and found the average Engel of the radical daily. The independent variable is the different pH levels and the dependent variable is the percent germination. This lab was completed so that the student can see the process of germination and have a better understanding of the concept. The student can also understand how the pH is crucial to the plants survival and how the pH affects the plant. Materials Three plastic cups Paper towels Pipette phi solution phi solution phi (tap water) -control Plastic bags 30 Blue Lake Bush beans Ruler Beaker Graduated cylinder Proceed rest 1 . Select three plastic cups for each of the three groups, one control group of pH 6 tap water and the 2 experimental groups of phi and phi water 2. Put 10 seeds in each of the plastic cups 3. Pour mol of the selected water into the cup with seeds in it. 4. Put label of what group the liquid is on the plastic cup. 5. Make observations of the seeds on day one. 6. On day two get three paper towels, one for each group of seeds. 7. Fold the towels so they will fit in Copilot bags comfortably. 8. Distribute seeds and selected liquid on to the paper towel evenly. 9. Transfer the label of what group the water is from the cup to the Copilot bag. 10. Check for germination of seeds and write percent germination in observations. 1 1 . Write descriptive data in observations 12. Rinse cups, place on drying rack. 13. Put the paper towel with seeds into to Copilot and close it. 14. Clean area and wash hands. 15. Next day check for percent of germination and record data in observations. 16. Change paper towels out for new ones, spread seeds out evenly again on new towels 17. Add correct solution of liquid to new paper towels. 18. Record data of any radical growth in observations.
