Solar Furnace – 30 cm Parabolic Reflector (KS3+)

This Solar Furnace is an excellent demonstration tool for illustrating the transfer of energy by solar radiation, making it perfect for KS3 and above. Featuring a 30 cm diameter parabolic reflector, the apparatus focuses incoming sunlight onto a black‑coloured copper cup, clearly showing how radiant energy can be concentrated to produce significant heating.

The demonstration visually reinforces key concepts such as radiation, absorption, reflection, and energy transfer, helping students link real‑world solar technology — such as solar cookers and thermal concentrators — to classroom learning.

Key Features

• 30 cm diameter parabolic reflector
• Concentrates sunlight onto a black copper cup
• Demonstrates energy transfer by radiation
• Clear visual model of how solar furnaces and solar concentrators work
• Sturdy construction suitable for outdoor class demonstrations
• Easy to set up and use in sunlight

Ideal for School Science Lessons

Perfect for KS3–KS5 physics, this solar furnace supports:

• Demonstrating radiation as a method of heat transfer
• Investigating how surface colour affects absorption
• Exploring renewable energy concepts and solar power
• Discussing real‑world uses such as solar ovens, solar heaters, and thermal concentrators
• Encouraging outdoor, practical learning linked to environmental science

Engaging, visual, and highly effective, this Solar Furnace is an excellent addition to any school physics department teaching heat transfer, energy, and renewable technologies.
