Phoneme Exercises
Start simple, recommends Karen Tankersley in her ASCD book The Threads of Reading: Strategies for Literacy Development (2003):
Introduce beginning sounds first.
Add medial and final sounds after the child has mastered the beginning sounds.
Select one-syllable words that isolate the initial letter. This method lets children clearly hear the individual sound being made.
As you speak the word (e.g., pat), draw out the sound of the initial letter so students can clearly hear the sound as it i...

Outline of the Natural Sciences Pt. II
The circulation of the blood was long since known; but the disposition of the vessels which conveyed the chyle to mix with it, and repair its losses; the existence of a gastric fluid which disposes the elements to the decomposition necessary to separate from organised matter, that portion which is proper to become assimilated with the living fluids; the changes undergone by the various parts and organs in the interval between conception and birth, and afterwards during the different ages of l... 1

You Can Choose Your Memories
In the earliest days of research, memory
was thought to be populated with socalled
engrams, memory traces that were
localized in specific parts of the brain. To
locate one such engram—for the memory
of a maze—psychologist Karl Lashley
taught rats to run through a labyrinth. He
then cut out various parts of their brain
tissue and put them right back into the
maze. Though the rats’ motor function
declined and some had to hobble or crawl
their way woozily through the twists and
turns, the animal...Folksonomies: memory mindfulness
Folksonomies: memory mindfulness
We can cognitively choose what memories will be stored longterm and which to let go, but we normally operate on autopilot, allowing novelties into our longterm memory-space.

The Science of Reconstructing Fossils
In my work on Fossil Bones, I set myself the task of recognizing to which animals the fossilized remains which fill the surface strata of the earth belong. ... As a new sort of antiquarian, I had to learn to restore these memorials to past upheavals and, at the same time, to decipher their meaning. I had to collect and put together in their original order the fragments which made up these animals, to reconstruct the ancient creatures to which these fragments belonged, to create them once more...Folksonomies: archaeology

All is Connected in Quantum Physics
Quantum theory thus reveals a basic oneness of the universe. It shows that we cannot decompose the world into independently existing smallest units. As we penetrate into matter, nature does not show us any isolated “building blocks,” but rather appears as a complicated web of relations between the various parts of the whole. These relations always include the observer in an essential way. The human observer constitute the final link in the chain of observational processes, and the properties ...Folksonomies: quantum physics elementary particles

The Fascinating Ability of Humans to Walk Upright
We stand upright-after a little practice-on a ship that rolls because we possess an array of sensory nerve cells buried in our muscles, skin, and joints. The function of these sensors is to provide a constant flow of information to the brain about the movements and location in space of the various parts of our bodies, as well as the environmental forces currently acting on them. We also have a pair of balance organs associated with our ears which work like spirit-levels, each having a bubble ...A wonderful description of everything that goes into the process of walking and standing upright.
