We outline protocols for producing slant-minis (SLINIs) and mini-deeps (MEEPs) and examples of their use in simple microbiology experiments suitable for high school students. The principal benefits of these protocols are decreased cost associated with significantly reduced media use; easier, less expensive disposal of waste; and increased safety…

Although the development of next-generation (NextGen) sequencing technologies has revolutionized genomic research and medicine, the incorporation of these topics into the classroom is challenging, given an implied high degree of technical complexity. We developed an easy-to-implement, interactive classroom activity investigating the similarities…

Illustrates ways to recycle plastic milk jugs into useful laboratory equipment. Among the uses described are storage containers, scoops, funnels, and flower pots. (MA)

Describes the construction of an insulated wooden wall incubator that combines excellent temperature control over the usual operating range with easy electrical access, low cost, and a wide potential size range. Presents a temperature- monitoring circuit, designed to measure the small temperature variations within the incubator, which could…

Described is the construction and use of an apparatus which applies liquid displacement to the problem of volume determination, giving accurate and repeatable results within 0.1 ml of actual volume measured. The apparatus is easily made from two jar parts, two bottle parts, and a burette. (Author/MA)

Describes the construction and use of equipment that measures low voltages of biological origin, including, for example, membrane properties of frog skin. (AL)

Describes a sensitive, simple, and inexpensive microrespirator that may be used readily by students. Discusses materials and methods for construction and classroom applications. (LZ)
