#86 i made the Tower Bridge of Sacramento in 3D view, going forward the circle and break the border, i think it can represent top 3 logo values that you need while keep it in a nice layout :
1 - Location: Sacramento, California (represented by the tower bridge, landmark of Sacramento)
2 - Science Teaching. Bridging the old to the new and/or bringing science forward or to the forefront (i choose the bridge as the object because it has the bridging meaning, and the graphic style with the perspective showing that it bring to forward)
3 - 3-dimensional learning (represented by the 3D style of bridge drawing)
What do you think about that ?
