Abstract
A teaching aid for use in conducting classroom experiments is disclosed. The teaching aid includes a transparent, flexible container with an opening at the top, and a rigid container having a rectangular cross-section for holding the flexible container. The rigid container has planar front and back portions, at least one of which is transparent. Accordingly, when the flexible container is disposed in the rigid container, students can easily view fluids and/or other materials held by the flexible container through the transparent portion of the rigid container during, e.g., a science experiment.
Claims21
A teaching aid, used for conducting science experiments involving fluids and/or other materials, the teaching aid comprising:
- a transparent flexible container having a closed bottom end and an opening at the top thereof, for holding the fluids and/or other materials;
- and
- a rigid container having planar front and back portions, opposing side portions, a closed bottom portion, an open top, and an elongated rectangular cross section, at least one of the planar front and back portions being transparent,
- wherein the flexible container is separable from and can be disposed in the rigid container with the opening of the flexible container at the open top, thereby allowing students to view fluids and/or other materials held by the flexible container through the at least one transparent portion of the rigid container during an experiment.
