Scientific Inquiry:
A farmer wishes to determine which of the two fertilizers, Brand X or Brand Y, helps his corn crops grow at a faster rate in a five-week period of time. He asks his daughter, whom is a college freshman taking introductory biology, to design an experiment to help him test each fertilizer. They decide to grow three different crops of corn, each grown in a controlled environment, receiving the same amount of sunlight, same climate, soil type, and water. Crop 1 will receive no fertilizer during watering. Crop 2 will receive Brand X fertilizer while watering. Crop 3 will receive Brand Y fertilizer while watering. The farmer and his daughter performed the experiment and collect data on each fertilizer over a five-week period. Use the data, represented in Table 1, to complete the following assignment.
Table 1. Average height of corn plants when treated with Brand X or Brand Y fertilizer compared to corn plants not treated with fertilizer (control).
| Time (T) in weeks | Control (cm) | Brand X (cm) | Brand Y (cm) |
| 0 | 0 | 0 | 0 |
| 1 | 1.3 | 1.4 | 1.2 |
| 2 | 2.4 | 2.7 | 2.3 |
| 3 | 4.2 | 8.3 | 7.3 |
| 4 | 6.8 | 12.4 | 8.2 |
| 5 | 8.7 | 16.8 | 11.6 |
Section 1: Representation
Define each term or variable, with respect to the scientific inquiry.
Independent variable-
Dependent variable-
Control group-
Experimental group(s)-
Hypothesis-
Write the equation to determine the average growth rate, with the appropriate values included, for each corn crop type (control, Brand X, and Brand Y). Use the equation shown below.
Growth rate = (T5 â T0)/5
Control =
Brand X =
Brand Y =
Section 2: Calculation
Solve the equations generated, in question 2, for each corn crop type. You must show your work, in the space below, for full credit.
Control =
Brand X =
Brand Y =
Section 3: Interpretation
Analyzing the data table and the calculated growth rates, complete the following questions.
Which crop type grew the fastest? Explain your answer using factual information.
Which plant was tallest? Explain your answer using factual information.
What can you conclude about the treatment of fertilizer on crop growth? Explain your answer using factual information.
Section 4: Application and Analysis
What could happen if the temperature were not controlled during the experiment? Would this impact treatment effectiveness on plant growth? Explain your answer.
Do you think the same outcome would occur if pine trees were used? Explain your answer.
If a particular fertilizer works on corn crops, should we be using that fertilizer on all plants? Why or why not?
INSTRUCTION: Answer all questions in this section. Each question carries 2 marks. Answer True or False to the following questions.
1. The cash conversion cycle of a firm is the length of time between the actual cash outflow for materials and the actual cash inflow from sales. To calculate this cycle, we need all the information used to calculate the operating cycle plus Days Payables Outstanding (DPO).
2. Net working capital is defined as current liabilities minus current assets.
3. Sales volume and collection period will be affected by a firm's credit policy.
4. Accounts payable, or trade credit, increases net working capital.
5. Efficient cash management is often concerned with speeding up the collection of cheques received and slowing down the payment of cheques issued.
Choose the letter a, b, c, or d that carries the best response.
6. The income statement reports the results of operations during the past year, the most important item being:
Net Income
Interest Expense
Earnings Before Interest and Taxes
Earnings Per Share
7. Which would represent claims against assets in the balance sheet:
Liabilities
Liabilities and stockholders' equity
Common stockholders' equity
Both common and preferred stockholders' equity
8. The two accounts that normally make up the common equity section of the balance sheet are and
accounts payable; accruals
common stock; retained earnings
long-term bonds; common stock
equity; liabilities
9. Accounting profits is different from net cash flow because
Net cash flow includes profits from operations.
Non-cash items are not included in the accounting profits
Net-cash flows take account of all non-cash items
Accounting profits overlooks depreciation and taxes
