Water is a simple chemical made from two gases - hydrogen and oxygen. Every molecule of water has two atoms of hydrogen and one atom of oxygen. With this lab, students can use electricity to separate the water back into hydrogen and oxygen!
This lab may be used to teach or reinforce many concepts, including:
-Forms/organization of matter (compounds, elements, mixtures, atoms, molecules)
-Properties of water
-Properties of electricity and electrical conduction
-Physical and chemical changes
Common Core Standard(s) Alignment:
CCSS.ELA-Literacy.RST.6-8.3 Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks.
