CLICK HERE FOR VIDEODr. Davies was leading us through the steps of doing a science fair project. We also learned how to trouble-shoot when things don’t turn out as planned.
Dr. Davies made CO2 (carbon dioxide) by mixing vinegar with baking soda, then found a way to measure the amount of gas it produced. Watch the video!
1. Heat oil in a heavy pot or deep fryer to 365 degrees (we used an electric skillet)
2. In a medium bowl, combine flour, baking powder, salt and sugar. Beat together egg, milk, and melted shortening; stir into flour mixture. Mix in the corn kernels.
Drop fritter batter by spoonfuls into the hot oil, and fry until golden. Drain on paper towels.
The first trial was not valid because we forgot to mix the BTB solution with water. We had to redo the experiment and concluded, after 3 trials, that the more you exercise, the more O2 your body needs, and you exhale more CO2 when you finish exercising. Picture one shows the failed trial. Picture two shows BTB solution blue (normal), Picture three shows BTB solution colored green because of the CO2 breathed into it. BY: R.R., M.L., J.D., A.L.
"We are mesmerized by the blue (cold) water staying at the bottom!"
2011-12 Video Dr. Davies VIDEO
Dr. Kevin Davies taught us the difference between the densities of hot and cold water. In the experiment, the hot water was colored red and the cold water blue. As you will observe in the video (click on VIDEO) the red rose to the top (less dense) and the blue sank to the bottom (more dense). Thank you Dr. Davies!
This experiment is a model of a volcanic eruption. There are two kinds of eruptions. A slowly oozing volcano or one that may explode with tremendous force. In this experiment, we are modeling the slowly oozing volcanic eruption. Click on the word “Video” above to see it in action for a better explantion. by A.M., K.C., S.H., and A.P.
We used a magnifying glass to observe the differences between rock salt and table salt. What we learned about these two salts is:
Table salt is rock salt that has been crushed and purified. There is little real chemical difference, as both are largely sodium chloride. Rock salt is found under halite.
