FarmBeats for Students – Part 2 Lessons

Lesson Description

Duration: 24-50 minute periods | Grades: 6-12

In this set of activities, students apply concepts from Activity Set 1: Fundamentals of Technology. First, students use Internet of Things (IoT) technology to select crops to plant in a garden and monitor their performance. Next, students transform their gardens into smart labs and conduct an agriscience experiment. Then, students install irrigation systems into their gardens using a relayed output device. Finally, students explore IoT technology applications in animal agriculture by brainstorming applications and developing a system flowchart.

Technology is only as efficient as how it is applied to solve problems. To increase farm production, traceability and food quality, technology implementation in agriculture has never been more critical. The application of technology can help farmers monitor production to aid in management and marketing decisions. Researchers are using IoT technology to reduce human error and increase their data validity during agricultural research. The use of relays allows producers to control operations using sensor data.

All agricultural concepts and performance objectives are associated with the Five Big Ideas.

Student Activities

This activity engages students in using IoT technology to define the environmental conditions of a garden. The data they collect aid their selection of crops to grow in their gardens. Students research and select companion plants to grow in their gardens. After planting the gardens, students use a Raspberry Pi with sensors to monitor the gardens.

Resources

Students develop parameters for an experiment as a class. They conduct the experiment with the FarmBeats kit, the data collection component of a smart lab. The experiment that students choose will be related to water and utilized during Activity 2.3 Relayed Outputs. Student groups monitor and collect data from their respective plants during this five-day experimental process. Students designate one group’s plant as a control and the rest as separate experimental groups. Data collected by the Raspberry Pis will be shared via Microsoft Excel for all groups to analyze collectively. Students submit a written report from the Student Journal that communicates the results of the experiment.

Resources

Students apply concepts from Activity 1.3 Thirsty Notification to design a relay-controlled irrigation system. The relay will turn on the power to a pump or a solenoid valve to deliver water to a plant or garden. Students design the irrigation system and construct it within their gardens. The conditions set by students will determine when the Raspberry Pi turns the relay on and off.

Resources

The IoT applications leading up to this student project have been plant-focused. Animal agriculture utilizes IoT technology as well. Students brainstorm an IoT system for animal agriculture and create a flowchart depicting the system. Then students present the flowchart and a basic sketch of the system to the class.
