Word List Author Note: [Vis. Mem.] Costello and Fant agree that the sign SCIENCE is also the sign for "chemistry." Dr. B performs this sign a bit higher. Costello's hint is similar to Dr. B's hint: like pouring test tubes. The point is to make movements 'across and down' at the top (pouring test tubes), not to make circles. Related sign vocabulary (initialized): Biology.
