Science+Fair+Notes+AJ


 * My science fair project is about Alka Seltzer pills dissolving in different temperature water. **


 * Hypothesis - I hypothesize that hot water will dissolve the alka seltzer fastest.**

=**source 1**= []
 * Procedure - First, you have three cups filled with hot,cold,and room temperature water. Second, you have a timer for each cup. But you test one cup at a time. You place the aka seltzer tablet in the hot then cold and room temp water at a time. Begin timer instantly. Third, write down your observations.**


 * It is an accurate/valid website because the people who work there know what they are doing and they are engineers and study a lot about this topic.**
 * ** Alka Seltzer contains citric acid and sodium bicarbonate. **

 * This is an accurate site because it helps children learn about the science concept ,and it is designed to match the syllabi of middle school and high school students in the U K.**
 * **Higher temperatures make reaction rates faster.**

=**source 3**= []
 * This is another accurate** **website** **because professors and scientists from a college developed the site based on their experiments.**
 * ** The graphs indicate how temperature affects reaction rates. **
