8 Water and its impurities

Water must be of a certain quality to be suitable for human consumption. No natural water found on Earth is pure; any sample of water contains more than just water molecules. Some materials, such as sodium nitrate, are very soluble and dissolve in water in large quantities, whereas other materials are much less soluble. This is just as well, otherwise rain would dissolve all the rocks and they would end up in the oceans!

Drinking water must not contain harmful materials, which means bot

In its seventh overtime game of the season, junior Vinny Saponari sent the Northeastern men's hockey team to its first triumph in extra time as the Huskies bested Massachusetts 22 seconds into overtime for the 4-3 victory on Friday night at Matthews Arena. Third-year forward Robbie Vrolyk supported Northeastern's efforts thanks to a two-goal performance while rookie Adam Reid netted the other tally in regulation. Vrolyk has notched three goals in his last two games as his last two-goal outing c

Southern Secession
This video is accompanied by text. "When Americans voted Lincoln president, James Buchanan officially became a lame-duck leader. Southerners worried that Lincoln’s victory, which received no support from the South, would lead to political and economic dominance by the North. Slavery, they feared, would be restricted and possibly outlawed. Southerners believed that by claiming their independence they could develop their own banking system and establish trade directly with Europe. No longer woul

Middle School Portal: Math and Science Pathways (MSP2)
This resource discusses how scientists and engineers study biological systems to develop artificial systems, in this case artificial olfaction. The sense of smell is extremely complex, and scientists working on artificial olfaction have had to study this biological system extensively to extract some basic principles upon which to build their devices. Disciplines of emphasis will involve biology, chemistry, electronics, and teamwork. Copyright 2005 International Technology Education Association

7.340 Learning and Memory: Activity-Controlled Gene Expression in the Nervous System (MIT)
The mammalian brain easily outperforms any computer. It adapts and changes constantly. Most importantly, the brain enables us to continuously learn and remember. What are the molecular mechanisms that lead to learning and memory? What are the cellular roles that activity-regulated gene products play to implement changes in the brain?How do nerve cells, their connections (synapses), and brain circuits change over time to store information? We will discuss the molecular mechanisms of neuronal plas
