Colorful Water Electrolysis

In my class students learn about chemical reactions and also the difference between elements and compounds. Students learn that the 5 signs of a chemical reaction are: 1) color change 2) gas production 3) precipitation 4) temperature change 5) change in properties (smell, texture, taste, density, etc.)

Students also learn that compounds are chemicals that have 2 or more elements bonded together, such as water. In this demonstration, students can observe the compound water undergo a chemical reaction, and break apart into hydrogen and oxygen gas. This demonstration can be done on an overhead projector so that all students can view it easily.
