Product Number: SA01210
In Stock (Ships within 1-2 business days)
Do plants only grow in soil? Not always. Sometimes they grow in water. In this essential life science activity, the science of hydroponics is used to supply plants with different amounts of key macronutrients and observe how the presence or absence of certain chemicals affects plant growth. The uniquely designed, transparent Lab-Aids® Greenhouse was designed for small, controlled investigations. This easy-to-use apparatus allows you to readily observe plant physiology, particularly root development. Additional experiments can be designed to investigate, observe, and gather data on variables such as aeration and temperature or to compare the speed of seed germination or plant growth. This highly graphic and unique activity can be used by individuals or in groups. Excellent activity for science fairs or projects. Number of simultaneously germinating seeds: 36 total, maximum six per chamber. Complete for six groups. WARNING: Choking Hazard. Small Parts. Not for children under 3 yrs.
