Cabomba caroliniana has been placed on the EU list of alien invasive species.
Under European Union regulations, “it is an offence in the UK to keep, cultivate, breed, transport, sell or exchange this species, or release it, intentionally or unintentionally, into the environment.”
Until we can find a native species that will perform in the same way in classroom photosynthesis experiments, we are using Egeria najas. See Egeria info.
Experiments with Egeria najas:
- Student activity 1 (includes teacher and technical notes)
- Student activity 2 (includes teacher and technical notes)
- Oxygen production – video using Cabomba
Activities with algae:
- Background notes on immobilised algae (originally produced by SAPS)
- Protocol for using immobilised algae
- Protocol for producing an algal tube
PowerPoint files (note these are provided here as pdf files; originals are available and can be requested):
