Young Scientists At Work
Foam is awesome! The foam made is special because each tiny foam bubble is filled with oxygen. The yeast acted as a catalyst (a helper) to remove the oxygen from the hydrogen peroxide. Since it did this very fast, it created lots and lots of bubbles. The experiment created a reaction called an Exothermic Reaction – that means it not only created foam, it created heat!
This experiment is sometimes called “Elephant’s Toothpaste” because it looks like toothpaste coming out of a tube. |
To understand a star’s atomic composition, astronomers measure the types of light emitted by the star. In this project, various chemicals were burned to understand how they’re molecules react to heat and how photons work. By burning different chemicals one can measure their energy levels and how the brain perceives them. This experiment is based on a modus operandi that is related to flame photometry, to examine the colour of light produced when an assortment of metal compounds are burned.
