Quazi-experimental research design was used. Research sample consisted of 60 students from secondary school province Hafr Al-Batin in Saudi Arabia, who divided into three groups, each group consisted of 20 students. The first group studied by timing style before lesson when using virtual lab, and the second group studied by timing style during lesson when using virtual lab, while a third group studied style timing after lesson when using virtual lab. Results showed that there were significant differences in the samples means favoring after lesson when using virtual lab.
