Answer:
First read the student guide to understand everything that will occur in this lab. Second read the safety guideline to ensure no one is harmed during this lab. Then gather your materials for the lab. After that section off your grass into 32 sections. Choose a quadrant and make some observations. Then choose a random sample area in your quadrant to estimate how many individual pieces of grass are present. Next, fid the average height of thegrass. Then, compare the data to quadrant #18. Plant your seeds. Count how many blades of grass are in your random sample area, and then calculate the estimated number of blades in your quadrant. Find the average height of the grass. Compare your data once again to quadrant #18, which is in the control group. Record the height of all the plants and calculate the average height for each type of plant. Compare this data with the data from quadrant # 18. Combine the data from all quadrants, and then compare the data from the experimental group to the control group. Make sure you record all your data.
Explanation:
A scientific explanation for a set of observations that can be tested and is written with an "if/then" statement is referred to as hypothesis and is denoted as option B.
