Let's learn about the science of wind with the handy anemometer "Kazedas"! - Title: 5th Grade Science, September Issue - Supplement: Kazedas (anemometer experiment kit) - Feature: Exploring the World of Light! - Target age: For 5th graders Thank you for viewing. Gakken's Science magazine is no longer sold, but I purchased a bulk of them before sales stopped. I believe the magazine is clean, with no writing, tears, or cut-outs. All the supplements are unused, but since they are unopened, there is no guarantee of the quality of the contents, and the instruments are items that you assemble yourself, so there is no guarantee of operation. Please understand this before making a purchase.
