Germination and Beans
Notes about bean germination: * The time to germination will decrease if you soak the beans overnight * It may take 7-10 days for the beans to ‘sprout’ * Make sure the paper towels remain moist for the duration of your experiment | | | | | | | | | |
Procedure
1. Think of 10-20 variables that may affect seed germination, recording them in Table 3. 2. From your list of variables in Table 3, select three to test. Form a hypothesis for why each affects seed germination. 1. Cold Temperature 2. Water (presoaked) 3. Warm Temperature 3. To germinate the beans, place one folded paper towel, moistened but not soaking wet, into the 5 x 8in bag. Place 10 beans in a horizontal line on the paper towel (between the paper towel and bag). 4. Label each bag with the variable being tested.
Table 3: Variables that may influence seed germination Variable | Hypothesized Effect | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 5. Hang each bag vertically using masking tape in the environment you select. 6. Create a table for your data, including title, units, and any other useful information. 7. Select the appropriate type of graph, and report the data you collected. 8. Write a lab report for this experiment in the space provided.
Lab report
Of the seeds germinated only 20 actually emerged as of this report.
The results are located in the following tables and graphs.
This graph shows the results of 10 beans; contained in 3 separate bags. 1. Containing seeds dampened prior to placement in container wrapped in damp paper towels. 2. Containing seeds placed in damp paper towels in cooler temperature. 3. Containing seeds placed in damp paper towels in placed in farmer temperature.
This graph shows the results of 10 beans; contained in 3 separate bags. 4.
