Construct hundreds of food chains and webs using up to 45 organisms and then model the populations. Incorporate digital photography and data logging. Investigate the influence of introduced species and biological control - levels of: Sewage Pollution - Phosphate - Nitrate - Turbidity and Thermal Pollution. Students can replace existing pictures with ones they have taken during their own pond study and even enter their own species into the environment. Integrate physical data collected about your pond by altering the physical parameters of the environment. The modelling software then works with your own ponds physical data and species. Web site support is available with additional species - pond environments and much more. Complete with site license - teacher resources and life-time upgrades.
