In a relaxed atmosphere, young researchers from the Collège de France presented the wealth of their disciplines, through surprising experiments entitled: Isolating DNA from plant tissue; Visualizing fluorescent samples with a laser; Building a microscope at home; What's new on the egg; Chemistry of Materials and Energy; Chemistry and Color; Complex Fluids; Molecular Cuisine.
Complex Fluids
The complex fluids stand presented liquids in supercooling, ferrofluids synthesized in the laboratory, and allowed visitors to discover how to reproduce an experiment at home giving rise to a non-Newtonian rheo-thickening fluid.
Building a microscope at home
High school students learned how to build a microscope using everyday materials!
Chemistry and Color
After visiting this stand, the public learned more about the origins of color, as well as the luminescence of everyday objects (luminous bracelets, glow-in-the-dark stars...).
Using a laser to visualize fluorescent samples
Young researchers at this stand demonstrated fluorescence with various solutions containing fluorophores used in biology.
Something new on the egg
Here, high school students could learn about embryonic development by observing a growing embryo inside its egg.
Isolating DNA from plant tissue
How do you isolate DNA from cells? The young researchers performed this extraction on a plant, the kiwi, whose cells are rich in DNA.
Chemistry of Materials and Energy
Through a series of experiments, from building a battery using only elements found in a fridge to "burning" water with lithium, the young researchers illustrated the superiority of lithium over older technologies.
