Development of an RGB Color Sensor & Its Application to Determine Urease Activity with Students at School

New laboratory activities have been developed to improve students’ scientific process skills. With the development of technology, teachers and students have the opportunity to use the new activities in their lessons. In this research, an Arduino-based activity was developed and then tested with different experiments. Students had the opportunity to practice some types of scientific process skills with regard to scientific facts (determining effects of variables; collecting data; measuring, reporting, and interpreting findings; and discussing possible reasons).
