Plants That Aren't Plants: Mosses and Lichens
Mosses and lichens are not given much attention in introductory biology laboratory courses, in part because instructors lack skills necessary to cover the topic-namely, moss leaf cross sectioning and lichen chemical spot tests. Acquiring confidence in just these two techniques, as well as familiarity with basic terminology, lays a foundation for further investigation.
Slide Right on By Using an Inclined Plane
Students explore building a pyramid, learning about the simple machine called an inclined plane. They also learn about another simple machine, the screw, and how it is used as a lifting or fastening device. During a hands-on activity, students see how the angle of inclination and pull force can make it easier (or harder) to pull an object up an inclined plane.
Sleeping Beauty Invades Rat's Genome
Knockouts are not just for Mice anymore. Aron Geurts and Howard Jacob from the Medical College of Wisconsin talk about their plans for creating transgenic rats using the Sleeping beauty transposon. Coming out of work pioneered by Colin Bishop's lab, Geurts and Jacob describe how the Sleeping Beauty system can be used to make transgenic rats and their plans to make the phenotype data from these rats available via the MCW PGA website (http://pga.mcw.edu) and the strains themselves accessible via a

Living and non-living things
Living things often rely on non-living things to accomplish daily tasks. Living things have several characteristics that non-living things do not, such as the ability to move, eat, breathe, and reproduce.

3.8 Revision questions
Hearing is a familiar and important human sense that is a topic naturally of interest to those who are curious about human biology. This unit will enable you to relate what you read to your own sensory experiences – and indeed many of the questions asked have exactly that function. This unit will be best understood by those with some biological understanding.
