---Based on these observations in several state elementary schools in Tegal City Center Java showed that the mastery of scince concept at a level below the standard. Students' life skills also need to be improved to face the 21st century.

This experimental study used the design of one group pretest and posttest. Retrieval of data using observation techniques, written tests and documentation. The results showed that the increasing in concepts mastery of ethnoscience-based integrated science, the development of life skills significantly by using guided inquiry with = 0.48 (medium) and the positive correlation between concepts mastery of ethnoscience-based integrated science and students' life skills with r correlation = 0.55 (medium).
