# 11th Grade Stoichiometry Of Nutrients In The Aquaponics System Lesson Plan Example (Science)

## Topic: nutrient stoichiometry in aquaponics systems

### Objectives & Outcomes

• To understand the roles that nutrients play in the aquaponics system, and how they are managed through the principles of stoichiometry
• To be able to calculate the amount of nutrients needed in an aquaponics system based on its productivity and uptake rates

### Materials

• Aquaponics system with water and fish
• Calculator
• Chart paper or whiteboard and markers

### Warm-up

• Begin the lesson by asking students what they know about nutrients and how they are managed in an aquaponics system. Write their responses on the chart paper or whiteboard.
• Next, show students an aquaponics system and ask them to observe how nutrients are managed in it.

### Direct Instruction

• Introduce the concept of nutrient stoichiometry, which is the calculation of the relative amounts of nutrients in a system based on the relative amounts of elements present.
• Using the handout with examples of different nutrient ratios, demonstrate how to calculate the stoichiometry of a given nutrient in an aquaponics system.
• Explain the importance of nutrient stoichiometry in an aquaponics system, including how it helps to prevent nutrient deficiencies and toxicities and ensure the health of the plants and fish.

### Guided Practice

• Have students use the handout with examples of different nutrient ratios to calculate the stoichiometry of a given nutrient in an aquaponics system.
• Have students compare their calculations to those of their peers and discuss any discrepancies.
• Discuss the role of nutrient stoichiometry in ensuring the health of the plants and fish.

### Independent Practice

• Have students use the handout to calculate the stoichiometry of a given nutrient in an aquaponics system.
• Have students create a poster or presentation to explain the role of nutrient stoichiometry in the aquaponics system and how it affects plant and fish health.

### Closure

• Review the concepts learned in the lesson.
• Ask students to share their posters or presentations with the class.

### Assessment

• Observe students as they perform the experiment and provide feedback on their understanding of independent and dependent variables, controls, and accurate measurement.
• Ask students to write a paragraph explaining what they learned about nutrient stoichiometry, or how the experiment changed their understanding of the concept.
