Question

Find what is wrong with these Scientific Method Experiments? Scenario 4: Metals and Rusting Iron.

A. Hypothesis lacks clarity
B. Variables not defined
C. Inadequate control group
D. Insufficient sample size

Answer 1

The student's scientific method experiments on metals and rusting iron have several issues including too few pots, multiple independent variables and dependent variables, and no control group for the soil.

Step-by-step explanation:

Scenario 4: Metals and Rusting Iron.

• a. The student has too few pots.
• b. The student has two independent variables.
• c. The student has two dependent variables.
• d. The student has no experimental control on the soil.

In this scenario, there are several issues with the scientific method experiments:

1. The student has too few pots, which may not provide enough data for a valid experiment.
2. The student has two independent variables, which can make it difficult to determine the cause of any observed effects.
3. The student has two dependent variables, which can also complicate the analysis of the results.
4. The student has no experimental control on the soil, meaning there is no comparison group to determine the impact of the hypothesized manipulation.

To improve the experiments, the student should consider increasing the number of pots, clarifying the independent and dependent variables, and including a control group for the soil.
