A team of six children (13-14 years old) developed and conducted an experiment to assess the behaviour of the planarian flatworm, an invertebrate animal model, before, during and after exposure to chemicals. The aim of the project was to engage children in pharmacology and toxicology research. First, the concept that exposure to chemicals can…

Some effects of copper and lead salt ions on the freshwater triclad, "Polycelis felina," are investigated in terms of locomotion behavior and survivability. Both the importance and the potential protective role of mucus secretion, which is a by-product of flatworm locomotion, are assessed. (Author/JJK)
