Building an outdoor plant box with a built-in calorimeter is a unique project that combines gardening with science. Here’s a step-by-step guide to help you create this functional and innovative planter.

Materials Needed:

- Wooden planks (cedar or redwood for durability)

- Screws and waterproof wood glue

- Insulating foam or thermal lining

- Calorimeter kit (or DIY components: thermocouples, data logger, and heat-resistant container)

- Soil and plants of your choice

Step 1: Construct the Plant Box

Cut the wooden planks to your desired size (e.g., 24"x12"x12"). Assemble the box using screws and waterproof glue, ensuring proper drainage holes at the bottom.

Step 2: Integrate the Calorimeter

Line the interior walls with insulating foam to minimize heat loss. Place the calorimeter components (thermocouples and data logger) inside a heat-resistant container, then embed it into one side of the box. Ensure wires are safely routed outside for data collection.

Step 3: Add Soil and Plants

Fill the box with nutrient-rich soil and plant your chosen greenery. The calorimeter will monitor heat exchange, useful for studying plant thermoregulation or environmental effects.

Step 4: Test and Maintain

Power the calorimeter and verify readings. Water plants regularly and check the system’s accuracy over time.

This project blends practicality with experimentation, making it perfect for gardeners and science enthusiasts alike!
