“…While in this first phase of research, we did not do a curiosity behavior comparison to scores; however, the psychometric results of the final selected items align with other ethnographic studies of science practices across settings -reinforcing the relevance of the items on SCILE scale to youth's everyday science activities. For example, a large research project (Bell, Bricker, Reeve, Zimmerman, & Tzou, 2013) based on an ethnographic study of a multicultural community of an elementary school found that children and their families selfreported an interest in mixing (Bricker & Bell, 2014) and in experimenting with things (Zimmerman & Bell, 2014), reinforcing the inclusion of two items: 'I mix things together to see what happens' and 'I experiment with stuff to see what will happen.' Given youth's interest in building, making, and tinkering (Bevan, Gutwill, Petrich, & Wilkinson, 2015;Wardrip & Brahms, 2015;Zimmerman & Bell, 2014), the two items 'I would like to invent something new' and 'I like to make things that no one else has made' fit well into the scale.…”
