Photosynthesis kit

07 February 2024

You can investigate the production of oxygen via photosynthesis using encapsulated algae. Students use alginate to quantitatively immobilise algae before placing them in vials. The vials contain an indicator solution that changes colour as the quantity of dissolved carbon dioxide changes. Learn more and check out our photosynthesis kit.

HOW TO APPLY

This kit can be posted to New 茄子视频app官网high schools and contains most of the chemicals and apparatus required. The kits are sent out fortnightly and the algae culture needs to be grown for 3鈥4 weeks before it is ready to use in the classroom.听

Please note: The Kit is available only to听senior biology classes at schools/kura.

听The kit contains
  • Preparation guide
  • Student guides
  • Algae drawings/photo sheet
  • Gel transmission spectra sheet
  • pH scale cards
  • Algae starter culture
  • Enrichment media
  • Alginate powder
  • Concentrated indicator solution
  • Coloured gel sheets
  • Black paper

You will also need
  • A two litre clear container (eg soft drink bottle)
  • Aquarium pump with tubing and diffuser
  • Foam or nylon wool
  • 18 watt low temperature light source (optional, a south facing windowsil will work but more slowly)
  • Magnetic hotplate stirrer adjustable to around 30-35掳C (recommended, a magnetic stirrer will do)
  • Calcium chloride dihydrate (CaCl2.2H20), 20 grams
  • Plastic pipettes
  • 7ml vials (or similar) for conducting experiments (up to 80 depending on number of groups and activities)
  • Sieves, small, 1 per group.

听Reuse

  • To reduce the amount of waste to landfill we encourage you to reuse the听kits. We can resupply a new algae culture and chemicals for future experiments.
