Day 4: Another Amazing Day!

As usual, we started our day with plenty of free time.  It is summer after all.  Many campers played box ball.  Others chose to play on the computers or Kindles.  A few built amazing things with Legos or played Magnetic 4.  For reading today we paired up a Tiger with a Dragon so that the youngest campers had a chance to read to the oldest ones. The Tigers had another math challenge on Sumdog, but this one was a little bit harder. The Dragons played math relay races with Master Sky, getting their exercise and math practice all at one time. Later, the Tigers had their own reading time so that they could continue with their summer reading books. Our competition team managed to fit in some extra training with Master Sky during lunch hour.   After lunch, the middle school group worked on their Algebra problems, while everyone else watched Teen Titans in the dojang.  Then, the Tigers practiced their language arts skills using IXL.com.  For science, we did the Coke test.  When you stick your tongue in Coke, there is a chemical on your tongue that changes the carbon dioxide in the soda bubbles into carbonic acid which irritates your tongue.  We previously learned about carbonic acid when we did the baking soda and vinegar volcano. Baking soda is also known as sodium bicarbonate, and it's a powder that reacts as a slight base. Vinegar is an acid, actually acetic acid in water.  When the two are mixed, a hydrogen atom effectively changes places with a sodium atom and we end up with two new substances - carbonic acid and sodium acetate. The carbonic acid then quickly breaks down further into water and carbon dioxide. It is the carbon dioxide escaping from solution that causes the frothy foam we are using as the lava for our erupting volcano. After science the Tigers worked out with Master Sky and the Dragons practiced reading on Sumdog and IXL.  Both the Dragons and Tigers ended the day with free time, including watching some World Cup soccer.  Check out some of the photos from today.
