Tastebud testing






Today we tested our taste buds. Mrs C talked about how we taste and how different parts of our tongues recognise different tastes. We tested sweet, sour, salty and bitter tastes.

Taste buds are sensory organs that are found on your tongue and allow you to experience tastes that are sweet, salty, sour, and bitter. How exactly do your taste buds work? Well, stick out your tongue and look in the mirror.

See all those bumps? Those are called papillae (say: puh-pih-lee), and most of them contain taste buds. Taste buds have very sensitive microscopic hairs called microvilli (say: mye-kro-vih-lye). Those tiny hairs send messages to the brain about how something tastes, so you know if it's sweet, sour, bitter, or salty.

We used ice cubes to make our tongues cod and see if we still tasted as well. Some of us did and some of us didn't.
