Prep Science Corner April 3rd

This week, we embraced an old tradition by dyeing real eggs using onion peels, herbs, and thread to create stunning natural patterns. The eggs were carefully wrapped with herbs, secured with thread, and then boiled in onion skin dye to reveal beautiful, unique designs.

The Science Behind Natural Dyeing

Onion skins contain flavonoids, such as quercetin, which act as natural pigments. When boiled, these compounds dissolve into the water and bond with the eggshell’s calcium carbonate, creating a rich, warm colour. The wrapped herbs block the dye in certain areas, leaving behind intricate, nature-inspired patterns. A wonderful way to celebrate Easter while exploring the science of natural dyes!

Year 6 put scientific thinking to the test by investigating whether yeast is a living organism.

Using yeast, sugar, and balloons, they observed how the yeast produced carbon dioxide, inflating the balloons as it fed on the sugar.

This exciting experiment demonstrated that yeast is indeed alive—it respires, just like all living things!

Year 5 wrapped up British Science Month with an exciting chemical reaction experiment!

The girls explored the chaos of chemistry by mixing bicarbonate of soda and vinegar, creating mini explosions of fizz and foam. This classic reaction, caused by the release of carbon dioxide gas, was the perfect way to end our celebrations—with a bang!
