Answer 1

Instructions: Use the lab example provided to complete the Practice Writing a Lab Report activity. Please fill in this lab report with the appropriate information and data from the lab scenario. Note: Use the information provided in the lab scenario to complete this assignment. DO NOT submit guided notes.

Title:
Include your name, instructor’s name, and the name of the lab

Objective(s):
What is the purpose of the lab?

Hypotheses:
What was the hypothesis in the experiment? The hypothesis should make a prediction of the outcome of your experiment and should include an explanation of why you expect that outcome.

Variables:

Independent Variable:
Dependent Variable:
Controlled Variable:
Materials:

Procedures:
The procedures are listed in Practice Writing a Lab Report Activity. You do not need to include them here.

Data Analysis:
Part 1: Include the data provided in the lab scenario here. If you were conducting an experiment, you would record your data in a table.

Days Height of Plant
No fertilizer (cm) Chemical Fertilizer (cm) Organic Fertilizer (cm)
1
2
3
4
5
6
7
8
9
10
Part 2: Using your data in Part 1, create a graph that represents the height of each plant over the ten days.

Insert chart [Hint: don't forget to consider the relationship between your data and the type of graph to best represent your data. A line graph would be the best option to analyze this data. Remember to give your graph a title.]

Conclusion:
Include the following as a summary paragraph in the conclusion of your lab report:

Analysis of the data-
Which fertilizer worked best? Explain.
Which plant did not grow well? Explain.
Rationale to support or reject John's hypothesis
Description of how the investigation could be tested further
Questions:

Explain what makes a scientific experiment reliable. Be sure to include at least three reasons to support your answer.
During research, why is it important to use peer reviewed evidence when collecting background information during a scientific investigation?

Answer 2

Lab scenario

John had a science fair project that he needed to do. He wanted to test the effects that organic and chemical fertilizers had on plant growth. John predicted that the organic fertilizer would make the plants grow taller. He used three pots, three of the same type of seed, soil, organic fertilizer, chemical fertilizer, water, and a ruler. John put soil in the pots. He added chemical fertilizer to the first pot, organic fertilizer in the second pot, and no fertilizer in the third pot. He then planted one seed in each pot. John had to daily water the pots. He also checked for growth and took measurements for a period of 10 days. He measured the height of the plants.

John made a data table to record his measurements.

Days No Fertilizer (cm) Chemical Fertilizer (cm) Organic Fertilizer (cm)
1 0 0 0
2 0 0 0
3 0 0 0
4 0 0 0
5 0 0.5 0
6 0 1.3 0
7 0 1.9 0.3
8 0 2.2 1.6
9 0 4.5 3.2
10 0.2 5.2 3.8
After the 10th day, John observed that the plant with the chemical fertilizer grew the most.
