Session 1 5 BCR A student reads an advertisement from a fertilizer company. The advertisement claims their fertilizer increases the growth of tomato plants by 25 percent. The student decides to perform an experiment to test this claim. She performs the following procedure. 1. Choose three similar-sized tomato plants. 2. Plant each tomato plant in a small pot. 3. Place all three small pots into one container and place on a window sill. 4. Add fertilizer mixed with water to Plants 1 and 2. 5. Add only water to Plant 3. 6. Record the heights of the three plants after four weeks. The student’s results are shown in the table below. THE EFFECT OF FERTILIZER ON TOMATO PLANTS Plant 1 2 3 Height (centimeters) 23 20 20 Analyze the student’s experiment to determine if it supports the claims made in the fertilizer company’s advertisement. In your response, be sure to include • a description of the data needed to support the company’s claim • an explanation of the results of the student’s experiment • an evaluation of the student’s experiment • a description of any changes you would make to the experiment; explain your answer Write your answer in your Answer Book.

Session 1 D irections Use the information and the diagram below to answer Numbers 6 and 7. Starch turns blue-black in the presence of iodine solution. A selectively permeable dialysis sac containing a starch solution is placed into a beaker of iodine solution. Iodine solution Dialysis sac Starch solution ■6 If the dialysis sac is permeable only to water and iodine, what will the solutions in the beaker and the sac look like after two hours? F The iodine solution in the beaker will turn blue-black; the starch solution will not change. ■7 Which of these processes is demonstrated by the experiment shown in the diagram? A B C cellular respiration active transport endocytosis G The starch solution in the dialysis sac will turn blue-black; the iodine solution will not change. D diffusion H J Neither solution will turn blue-black. Both solutions will turn blue-black. Biology Public Release 2005 Page 5 Copyright © 2005 by Maryland State Department of Education.
