Stimuli

A farmer is considering different methods to improve crop yield in their vegetable garden. They currently use traditional methods, but have noticed neighboring farms using hydroponic systems with significant success. The farmer is concerned about the cost and initial setup time of hydroponics, but also desires higher yields. They've gathered some data on yield and cost for each method.

Method	Average Yield (kg/season)	Estimated Setup Cost ($)	Estimated Operational Cost per season ($)
Traditional	150	0	50
Hydroponic	250	500	100

Analyzing

Based on the data provided, what is the approximate additional yield per season if the farmer switches from traditional to hydroponic methods? Show your calculation.

Creating

Design a simple cost-benefit analysis table for the farmer to use over the next 5 seasons. Include columns for method, initial setup cost, operational cost per season, total cost over 5 seasons, and average yield per season. Assume the current traditional yield remains stable.

Evaluating

Based on the analysis and the design table created above, consider whether the farmer should switch to a hydroponic system. Explain your evaluation, discussing the trade-offs involved – factoring in not just cost but also time and effort. Which factors are most important in making this decision?

This quiz analyzes different agricultural methods, focusing on traditional and hydroponic systems for vegetable gardening. It involves evaluating the costs, yields, and potential benefits of switching methods. Participants will calculate additional yield from the data provided.
