Solar Hot Water Demo
Grades 8-12. For your STEM curriculum.
Dramatically shows students how heat from the sun can be captured by a black ABS plastic panel and stored for future use. A length of tubing is run through a carefully cut groove. The water inside the tubing absorbs heat from the panel. As the panel heats up, the water inside the tubing quickly rises in temperature, reaching 90° F in just a few minutes if in direct sunlight. Inclined valve prevents water from escaping. Kickstand holds 10 in. x 16 in. panel at a 30° or 60° angle. Includes syringe for filling.
WARNING: Choking Hazard. Small Parts. Not for children under 3 yrs.
