It is nice to experiment, but what do the colours means? (A) The principle of dilution with coloured chemistry workshop. Methylene blue serial dilutions in multi-well plates. (B) Dilutions of strawberry syrup in water to correlate the decrease in colour observed with the decrease in taste according to the dilution made. (C) The pH of water workshop. Using pH paper to measure water pH used for fish rearing. (D) Impact of pollution on the food chain workshop. Experiment that mimics the impact of an oil spill on aquatic organisms through the modification of air/water gas exchanges due to the hydrophobic nature of oil. (E, F) DNA extraction performed during the genetics workshop. |
