LABORATORY REPORTS

The following tutorial is designed to aid you all year long in writing lab reports, one of the most important parts of your grade!

The sample report below is an “A” report. Does your report look like this? You may select any heading to see a list of common errors made in that given section.




MUSTARD SEED GERMINATION LAB


OBJECTIVE: <-----Notice all sections have headings that stand out
What effect does the amount of water given to seeds have on the rate of seed germination?

Notice that the report is single spaced with larger spacing between sections for a neat clean look.

INTRODUCTION:
Most plants start out life as a seed. In order to germinate (or sprout) seeds need a supply of water in addition to other nutrients. In this lab the effect of varying amounts of water on seed germination will be investigated. Mustard seeds will be used for this experiment mainly due to their small size. A number of seeds will be placed in two beakers containing different amounts of water. The beakers will be monitored over three days in order to reach a conclusion.


PROCEDURE:
1. Place 50 mustard seeds in each of two small beakers.
2. Label one beaker FIVE and the other beaker THIRTY.
3. Using a graduated cylinder pour 5 mL of water into the beaker labeled FIVE.
4. Using a graduated cylinder pour 30 mL of water into the beaker labeled THIRTY.
5. Cover each beaker with a lid.
6. Set the beakers aside for 24 hours.
7. After 24 hours count the number of seeds in each beaker and record.
8. Repeat Step 7 after 48 hours from initial set-up and again after 72 hours.

DISCUSSION:
The effect of water on seed germination is that more water enhances the rate of germination. Although all the data are not in agreement this is the best conclusion that can be reached. In all likelihood it takes some time before this effect is realized. In this lab seeds were monitored for germination at three different intervals. As shown in Table 1 the beaker with more water had a greater amount of seeds germinate in two out of the three intervals. Also, the greatest difference was seen in the last interval where the beaker with more water had almost double the number of seeds germinate. Even though more seeds sprouted at the 24 hr period in the 30mL beaker this is too small a sample to make a good conclusion (2 to 3). In the 48 hr period more seeds germinated in the 5mL beaker, but this difference was also slight (12 to 10). My conclusion is based primarily on the 72 hr measurement, which shows a large difference between results (19 to 35). Most likely time also plays an important role in determining the rate of germination. If this lab was extended to 96 hrs my conclusion would probably be supported by that data as well.
