Seed Lab I. Purpose/Question: A. What is the variable you are testing? Radish seed vs. Pea seed B. Question 1: How does seed type affect when the seeds germinate? C. Question 2: How does seed type affect the length of the stem? II. Research: List two pieces of information you learned about the variable you are testing below. The radish stem was longer. Both seeds germinated equally fast. III. Hypothesis: Make these an “If-then” statement and do not use pronouns (I‚ we‚ he‚

Title- Mitosis Abstract –For this lab there is no experiment to be done only questions to be answered. In this experiment we will categorize and count the cells to compute the mitotic index of the total root area. Introduction – The purpose of this experiment is to answer questions associated with the onion root tip photos that are pictured in the lab. The questions for this lab will be drawn from the discussion and review section at the beginning of the mitosis lab. Once that section has been reviewed

Lab 6.C Hypothesis: If enzyme activity is affected by the pH of a solution‚ then the enzymes will experience the greatest activity at a pH of 6. Variables: Independent Variables Dependent Variable Controls Four different pH values (10‚ 7‚ 6‚ and 3) Change in color of the solution The amount of potato extract‚ pH solution‚ and catechol used (1 cm +/- .1cm) Size of the test tubes Amount of time allowed for the catechol to sit with the potato extract and pH solution (20 minutes with 5
