This short video segment from IdahoPTV's D4K shows a diagram of the parts of the tongue. It explains how papillae, taste buds and tiny hairs work to help you decide if food is sweet, sour, bitter or salty.
CHILD: Your sense of taste begins with your tongue.
JOAN CARTAN-HANSEN: Your tongue is covered with thousands of tiny bumps called papiliae. Inside those bumps on the back part of the roof of your mouth and in the very back of your throat are 10,000 taste buds. The tiny cells have little hairs. Dissolved food particles seep into the hairs and the taste buds sense whether the food is sweet, sour, bitter or salt. That information is sent to your brain and then you decide if the food is good or bad.
CHILD: Did you know most of your sense of taste comes from your sense of smell?
CHILD: So let's share.
Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
