Abstract: The present invention relates to an educational method and apparatus for the instruction of basic scientific principles relating to mining. The apparatus consists of a kit for science instruction that comprises a topographic mold, casting compound, and one or more components simulating materials found in nature beneath the surface of the earth. The kit may include a tool for obtaining core samples of the resulting topographic model and may include a topographic map. The components of the kit may be used in conjunction with weight measurement tools.

Abstract: Insects, such as fruit flies, are quickly anesthetized while contained in a culture vessel of the type having a mouth closed by a flexible porous plug by immersing one end portion of an elongate slender applicator wand in a volatile liquid anesthetic and then inserting the applicator wand between the wall of the culture vessel and the porous plug without removal of the plug and without creating an opening therebetween to allow the insects to escape and positioning the end portion of the applicator wand inside the culture vessel to thereby quickly expose the insects in the culture vessel to the anesthetic.
