"Go confidently in the direction of your dreams. Live the life you have imagined." - Henry David Theorean

To our dearest graduate Science Club Officers, there aren't enough words to describe how proud we are for y'all. Your efforts have been rewarded. Best luck to your college journey, Padayon!

Nearly 97% of the world’s water is salty or otherwise undrinkable. Another 2% is locked in ice caps and glaciers. That leaves just 1% for all of humanity’s needs — all its agricultural, residential, manufacturing, community, and personal needs.

There are 117 million lakes on Earth, covering 3.7 percent of the continental land surface.

Most lakes are relatively small – 90 million lakes are less than two football fields in size.
Most lakes lie low — 85 percent are at elevations less than 1,600 feet (500 meters) above sea level.

68.7% of the fresh water on Earth is trapped in glaciers,
30% of fresh water is in the ground.

1.7% of the world’s water is frozen and therefore unusable. Approximately 400 billion gallons of water are used in the United States per day. Nearly one-half of the water used by Americans is used for thermoelectric power generation. In one year, the average American residence uses over 100,000 gallons (indoors and outside).Water can dissolve more substances than any other liquid including sulfuric acid. The freezing point of water lowers as the amount of salt dissolved in at increases. With average levels of salt, seawater freezes at -2 °C (28.4 °F).

The Dead Sea is famed as the Earth’s lowest point.

The sea’s elevation is 430.5 meters below sea level. The Dead Sea is the world’s deepest salt lake (hyper saline) and has 34.2% salinity, which is 9.6 times that of the ocean. Due to the high salt content of the water no living creature (not even microscopic aquatic organisms) can live in the sea. This explains the name - “Dead” Sea.

Most freshwater is in ice.

Just 3.5 percent of Earth’s water is fresh—that is, with few salts in it. You can find Earth’s freshwater in our lakes, rivers, and streams, but don’t forget groundwater and glaciers. Over 68 percent of Earth’s freshwater is locked up in ice and glaciers. And another 30 percent is in groundwater.

Bacteria that use photosynthesis are called photoautotrophs. Some types, for example cyanobacteria, produce oxygen. These probably played a vital role in creating the oxygen in the earth’s atmosphere. Others, such as heliobacteria, do not produce oxygen.

When you pop a pill to kill off a bad bug, you kill some of the good guys, too. A bacterium called Clostridium difficile can move into the prime intestinal real estate cleared out by antibiotics, causing painful inflammation and diarrhea.

When two individuals kiss, they interchange in between 10 million to 1 billion bacteria with each other.

We’ve already established that our mouth is full of bacteria and when two people engage in a kiss, they exchange from 10 million to 1 billion bacteria approximately. Isn’t that crazy? In just a 12-second kiss, one can exchange around 80 million bacteria with you, so think carefully about that the next time you are in that situation.

A clean mouth has between 1,000 and 100,000 bacteria on each tooth. If that makes you squirm, consider this. The human body is home to some 1,000 species of bacteria.

Solar panels crown rooftops and roadside signs, and help keep spacecraft powered. But how do solar panels work?

Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity, according to the University of Minnesota Duluth. Solar panels actually comprise many, smaller units called photovoltaic cells — this means they convert sunlight into electricity. Many cells linked together make up a solar panel.
