Hydroponics can help students understand several STEM subjects at the same time because it combines **biology, chemistry, technology, engineering, and mathematics** in one practical learning activity. Students can observe how plants grow without soil, study nutrients and water conditions, and use sensors to monitor factors such as moisture, temperature, or pH.
For example, students can:
* **Study Biology:** Learn about plant growth, roots, nutrients, and photosynthesis.
* **Explore Chemistry:** Understand nutrient solutions, pH, and water quality.
* **Apply Technology:** Use sensors, controllers, and automation to monitor the system.
* **Practise Engineering:** Design and improve structures for growing plants and circulating water.
