2. Colegio San Patricio Science Fair Project 2009 Title Team Members Teacher Jesus Carvajal Ms. Claudia Vilchis Ma. Fernanda Corona Grade Felipe Cuellar 5F Jesús Carmona Fidel Cantú Project Description Which battery last longer Everactive, Eveready, Energaizer, Duracell or Duracer ultra? Project Hypothesis We think Duracell Ultra last longer because it’s more expensive. Project Area Chemestry. Project Type: Investigation and experiment. Abstract Battery of AA are made of positive cover, can, electrolyte, label, anode, cathode, current collector, separator seal, neutral cover and negative cover. The purpose of our experiment is to know which battery last longer. We used a chart for recording the results to see which is the best of all the batteries we used. The batteries that we used were 5 different brands.

6. Conclusion

7. Research There are numbers of differences between the male and female foot. For example, the male's foot has much more square shape that that of a female. The female foot is broader across the toes than a male's. Also, a female's foot has a narrower heel than a male's. Females are usually at higher risk for feet problems than males. This is because females wear high heels often. This puts all the wait on the toes and therefore puts strain on the foot and leg muscles. When asked whether or not women would still wear high heels if they knew it caused feet problems, 2 out of 3 answered yes.
