This is a booklet to help students record their snow line experiment. First, students fill a mason jar with snow. Then they mark the snow line on the jar in the booklet one color (older students can measure the exact snow line and write that in the booklet too). Next, using a different color, students mark their prediction of where the snow line will be when the snow melts. Last, after the snow melts the students mark the actual water line in a third color. (Note - the boxes on the right of the booklet are to be color coded to reference the three colored lines on the jar).
