I've gathered together all the science materials my son used in elementary school, along with the maps he used in social studies, and the binder (with a pocket) he used for field trips, etc. Science Materials: Wind and Rubber SP Air and Water K Plus Seed Germination and Growth DX Social Studies: Hyogo Prefecture Map (Land Elevation) Scale Binder: Back (Pocket) This is a set of 5 items. The price is almost equivalent to the shipping cost, but I'd like to give it to someone who can use it. I think it would be interesting for children who like science.
