GROUP 4 SNAILS Physics: To investigate the power of a snail's mucus on different surfaces Chemistry: to determine what percentage of a snails shell composed of CaCO3 Biology: To investigate taxism in snails 13 September 2004 Rafael Bravo Ana Gosnar John Kjeldgaard Marianne Sangster PHYSICS To investigate the strength of a snail's mucus on different surfaces Planning A Our research question: At which angle does the snail's mucus fail to hold the snail and how different surfaces (solids and liquids) affect it? Hypothesis: We predict that the snail's mucus is rather strong; therefore it can hold a snail at quiet steep angles. Since a snail is rather small (approx. 20 g), we predict that the mucus is subsequently strong enough to hold the snail until the angle is rather large (150°). We also predict that different surfaces will affect the mucus's strength. If the surface is smooth the snail will not grip on to it as strong as if the surface would be...
