Learning science involves learning important concepts, conducting experiments to see first-hand how researchers discovered and confirmed some elements of science concepts, and learning how to think scientifically. With this complete approach to learning science, students are well-prepared to deal with the natural world around them and to make wise decisions when confronted with various choices. The ability to think scientifically is a valuable skill in almost all aspects of life and doing science teaches scientific habits of mind. Students can do science through research projects ...

Consider the rain gauge used in GLOBE, CoCoRaHS, and other citizen science programs. Just four pieces plus 2 mounting screws – an inner graduated cylinder, an outer cylinder, a cap/funnel, and a mounting bracket. The area of the outer tube is exactly 10 times the areas of the inner tube and the cap/funnel, so the graduations on the inner cylinder can be spaced ten times further apart. Thus, 0.2 mm of rain fills the inner tube to a depth of 2.0 mm, which one can read. In addition, if heavy rainfall fills the inner cylinder, the rest of the rainfall overflows into the outer cylinder, ...
