Label that Diagram - Chemistry

This app provides high school and college science and chemistry students a chance to study, learn and practice the information in seven diagrams. The diagrams included are an Electrochemical Cell, Heating Curve, Reaction Potential Energy Diagram, Electrolytic Cell, Phase Diagram of Water, Contact Process for Making Sulfuric Acid, and a Dry-Cell battery. Users may study the diagrams and then practice identifying the parts of the diagrams. This app is appropriate for High School and College students.

As each screen is played, the user sees the Number Wrong, Total Done and the Accuracy. The final scores are displayed in a Report Screen at the end of the game. The accuracy is the percentage of correct selections out of the total selections taken. An accuracy of 100% means that each selection was the right answer. There is a Help Button which will flash the correct answer on the diagram. Using Help counts as a wrong answer.

This app has been tried on a Smartphone, a 7-inch tablet and a 10-inch tablet and an Android TV. It should run fine on any devices with an Android version 5.0 or higher. This program is also available in a Window's version.
