Jordan is doing a science fair project on the effects of music and growth of tomatoes.he has two tomato plants, plant A and plant B that he grows in a window and gives the same amount of water. Plant A is exposed to classical music using headphones atttached to the soil. Throughout the growth period, Jordan counts the number of tomatoes produced by each plant.

Plant A=35 tomatoes
Plant B=55 tomatoes
What is the manipulated variable?
What is the responding variable?
What should jordans conclusion be?
What should he do different?

I feel as if the answer helped me a little bit, but according to other sites its telling me different answers. What the constant? What hypothesis can he made? I'm really looking for the answers to help me with this worksheet and its basically not helping me at all! but thanks anyway :)

The manipulated variable in this experiment is the exposure to classical music. Jordan intentionally exposes Plant A to classical music using headphones attached to the soil, while Plant B is not exposed to music.

The responding variable in this experiment is the number of tomatoes produced by each plant. Jordan counts and compares the number of tomatoes produced by Plant A (35 tomatoes) and Plant B (55 tomatoes).

Based on the results, Jordan's conclusion should be that the exposure to classical music had an impact on the growth of tomatoes. Plant B, which was not exposed to music, produced more tomatoes (55) compared to Plant A, which was exposed to music (35).

To improve the experimental design, Jordan should consider implementing the following changes:

1. Increase the sample size: Conducting the experiment on only two tomato plants may not yield statistically significant results. Jordan should consider increasing the number of plants in each group to obtain more reliable data.

2. Randomize plant assignment: It is important to assign plants randomly to each group (music/no music) to minimize potential bias. This can be achieved by labeling the plants and then randomly selecting them for each group.

3. Control other factors: Besides water, it is essential to ensure all other environmental factors, such as temperature, light intensity, and humidity, remain constant to isolate the impact of music on tomato growth.

By making these modifications, Jordan can conduct a more robust experiment to further investigate the effects of music on tomato growth.

The manipulated variable is the variable which is intentionally changed or manipulated by the experimenter. In this case, the manipulated variable is the exposure to classical music using headphones attached to the soil. Jordan is intentionally exposing plant A to classical music while he does not expose plant B to any music.

The responding variable, on the other hand, is the variable that is observed and measured to determine the outcome or effect of the manipulated variable. In this experiment, the responding variable is the number of tomatoes produced by each plant - plant A and plant B.

Based on the results, we can draw the following conclusions:
- Plant A (exposed to classical music) produced 35 tomatoes.
- Plant B (not exposed to any music) produced 55 tomatoes.

From this data, it seems that the classical music exposure did not have a beneficial effect on the growth of tomatoes. Therefore, Jordan's conclusion should be that the classical music exposure did not significantly influence the growth of tomatoes.

For future experiments or improvements, Jordan could consider making the following modifications:
1. Increase the sample size: Using only two tomato plants (one exposed to music and one without exposure) might not be sufficient for reliable conclusions. Increasing the number of plants in each group would help reduce the effect of any outliers or anomalies.
2. Control other variables: It is important to ensure that all other growth conditions, such as light exposure, temperature, and soil quality, are kept constant for both plants. This will help isolate the effect of the manipulated variable (music exposure) on tomato growth.
3. Repeat the experiment multiple times: Conducting the experiment multiple times and obtaining consistent results would add credibility to the findings and increase the reliability of the conclusions.

By incorporating these improvements, Jordan can conduct a more robust experiment to investigate the effects of music on tomato growth.

music

number tomatoes
no conclusion
expose a few tomatoes to hard rock , and compare that to quiet, and to classical music.
