Smelling and Tasting
If you can't smell, you probably can't taste very well either. They are closely related functions. Receptor cells for taste and smell are located in the mouth and nose, respectively. As the receptor cells are stimulated, they send impulses from these organs to the brain's smelling and tasting centers, the cortices. For taste, impulses stimulated by the chemical compounds in food are sent to the gustatory cortex. For smells impulses stimulated by the chemical compounds in odors are sent to the ol

Sesame Street: Dancing With Triangles -- Shapes For Younger Learners
This is an amusing spoof of 'Dancing With the Stars'. This Sesame Street video shows a dance competition that is supposed to involve triangles, but the contestants are a little confused. Other shapes such as a hexagon and a square are introduced, in addition to the triangle.
Area of Diagonal-Generated Triangles of Rectangle are Equal
In this video, Mr. Khan draws a box and two intersecting lines that produce several triangles. Mr. Khan proves that the area of these diagonal-generated triangles of the rectangle are equal. He goes over the formula for finding the area of a triangle. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education. The screen gets busy (and dark)--the viewer may want to open to 'full screen' to see everything. The sound is a little low. (04:35)
What Is the Pythagorean Theorem and How Do You Use it?
The Pythagorean theorem is a formula used to solve side lengths of a right triangle, and it is expressed as A squared plus B squared equals C squared. The instructor uses a document camera to model what the Pythagorean Theorem is and how to use it.
Explore went to China on a fact-finding mission led by Charles Annenberg Weingarten, a trustee of the Annenberg Foundation. During the three-week trip, the team discovered many of China's hidden gems: philosophy, art, education, and rural life. They also discovered how the country's hard-working and innovative leaders were working to solve issues of the environment, human rights, and public health.
Rural schools, where the vast majority of children in China receive
their primary education, are often below the standards of their urban
counterparts. About 80% of rural schoolchildren don't get past middle
school, and many face difficult life prospects as they become teenage
farmers and migrant workers. But at AnWu Elementary, the explore team
saw the results of the school's vigorous improvements, and students
share their big hopes for the future with

Teaching Kids Real Math with Computers
From rockets to stock markets, many of humanity's most thrilling creations are powered by math. So why do kids lose interest in it? Conrad Wolfram says the part of math we teach -- calculation by hand -- isn't just tedious, it's mostly irrelevant to real mathematics and the real world. He presents his radical idea: teaching kids math through computer programming. (17:13)
Never Mistake Activity for Achievement
