Yesterday was a great day of filming for our onsite 5th grade science program! This is our educator, Alicia, preparing for "lights, camera, action!"
Into the scientific method? Do you dig quantitative observations? Are marshes and estuaries and salt water your thing?
Check out the "Sotka Laboratory" by first scrolling over "science" and clicking on the "scientific inquiry" tab.

Did you know you know that the British, or Red Coats, had burned our Capitol and attacked the city of Baltimore which was the third largest city in America ...long before the ball team existed? Did you know that Dr. William Beanes, was related to Francis Scott Key by marriage?( Key was asked to sail and try to get his relative freed.) Did you know that a storm caused the ground of Fort McHenry to become so wet the cannons fired by the British sunk into the mud? Did you know Key and those he was with were kept under guard by the British as they watched in dismay for over 25 hours as bombs were being shot at Fort McHenry? Did you know that Fort McHenry was named for Secretary of War James McHenry, who had signed the Declaration of Independence? Did you know that words of a previous poem written 9 years earlier were reworked and would become the "Star Spangled Banner?" And my favorite...Did you know Key's words were NOT written on an envelope as often stated as envelopes were not around until 1901 or later? So...now you KNOW!!! As an American, I'm grateful for the words and the history behind those words written so long ago. Happy 200th Birthday "Star Spangled Banner," and long may she wave!!! Today is National Day of Encouragement! Encouragement is the act of making someone "more determined, hopeful or confident." So do your part with kind words and actions today!
Tomorrow is 9/11. Some of you reading this were very young when our nation experienced the loss of so many lives in New York, Pennsylvania, and Virginia. Many places are holding remembrance ceremonies or recognizing the day by flying flags at half staff. Your school might be one of them. Tomorrow will be a solemn day and you can honor those lives that were lost with a moment of silence.
What type of water is rain? Is it salt water? Fresh water? Where does rain come from? The ocean covers 71% of our Earth. Ocean water is SALTY. As the sun heats up the ocean surface, water molecules in the ocean evaporate! EVAPORATION is a part of the water cycle. Evaporation involves heat, which can turn water into water vapor or steam. When it is hot enough, water vapor leaves our ocean, rivers, and streams and rises into the air and stays in our atmosphere. In Oscar I Am, Oscar, Hank, and Hannah begin their adventure as water vapor, in the form of a cloud. The three friends later condense into water droplets and fall down as rain over the SC mountains. They took place in PRECIPITATION.
Rain is a form of precipitation. Rain water is FRESH water. There is no salt present in rain water. So what happens to the salt in the ocean water as it evaporates into the atmosphere?! Salt water is a SOLUTION. A solution is two substances that are evenly mixed together. There are two parts: the SOLUTE and the SOLVENT. A SOLUTE is the substance being dissolved and the SOLVENT is the one doing the dissolving. SALT WATER = SALT (SOLUTE) + WATER (SOLVENT) So as evaporation takes place in the ocean, salt molecules stay behind, while the water molecules enter our atmosphere as water vapor, free of salt! |
