Each group needs:

• hydrogen generator, refer to the Hydrogen Generator - Teacher Preparation Instructions for required materials (gas generator kit, chemicals, lab equipment, etc.)
• oxygen generator, refer to the Oxygen Generator - Teacher Preparation Instructions for required materials (gas generator kit, chemicals, lab equipment, etc.)

NOTE: alternatively, prepare a hydrogen bag generator and an oxygen bag generator for the entire class to use; refer to the Gas Bags - Teacher Preparation Instructions for required materials

• 2 pipette bulbs (a plastic pipette with an approximately 15 ml bulb; the plastic stem must be cut and the hole in the bulb must be large enough to fit over the gas outlet tube in the generators)
• 2 x 250 ml beakers filled with water, to hold generators and maintain constant temperature
• book of matches
• short candle
• safety glasses/goggles, pair per person
• chemical-resistant gloves, pair per person
• Microscale Experiment with Hydrogen & Oxygen Combustion Worksheet, one per person
