Lab 2: Writing a Lab Report 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. 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. 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. Variable | Hypothesized Effect | In the fridge | I don’t think that it will grow because it is too cold | On the window sill (lots of light) | I think that this seed will grow n problem | In a dark closet | Will not germinate because of no sunlight | Coffee table (minimum sunlight) | Will germinate but growth will be slow | On top fridge (moderate light, warm temp) | I think this will be the second tallest bean | In the bathroom (florescent light, hot temp) | No germination | Outside the window (cold temp, lots of light) | I think that the bean will freeze and will not germinate | Place in salt water (lots of light) | I think that the bean will germinate and will grow | Placed in tea (lots of light) | I think that this will grow very tall because of the caffeine in the tea | Placed in sugar water (lots of light) | I do not think that the sugar water will have an effect on the growth of the bean | *results were measured 10 days later Variable | Growth measured in centimeters/ largest growth | In the fridge | No germination | On the window sill
