Our task was to familiarize with the concepts of pH of the solution, pH scale, pH indicators metso using ICT. Use of the Internet developed theoretically the above issues, and then moved around circles class experience by which we tested the pH of solutions and their pH was dubbed.
After the knowledge metso we had in the house to investigate experimentally the pH of the various articles of daily use and re-using metso Tiku learn pH and the pH level of human skin, urine, gastric juice, blood, saliva and what are sores.
ICTs have also used in preparing our presentation, which presented, among others, chemistry lessons in classes of second high school. In addition, mobile phones, social networking sites have served us to communicate with each other during operation, as well as to consult with our guardian Mr. E. Gołębiewska. At present we used the camera taking pictures and laptop to the projector.
