Heads or Tails? Studying Regeneration in Planaria

Students investigate stem cells. In this science lesson, students discuss stem cells and view a video about human embryonic development. Students conduct the pulse-chase.

Cell specialization is amazing! How do they know what they should become? A video from an interesting biology playlist examines the process of cell specialization. Content includes where we find specialized cells, types of specialized...

All cells are created equal, but some go on to do amazing things! Find out more about these super hero cells with a short video from a well-written biology playlist. Topics include specialized plant and animal cells and how cells know to...

A cell of another color is still a cell. Pupils color a cell to identify its structures in the fourth segment of a seven-segment series. Groups work together to build a three-dimensional cell membrane segment, which is combined with...

Students learn about the different structures that comprise cell membranes, fulfilling part of the Research and Revise stages of the legacy cycle. Students view online animations of cell membrane dynamics (links provided). Then they...

Students color-code a schematic of a cell and its cell membrane structures. Then they complete the "Build-a-Membrane" activity found at http://learn.genetics.utah.edu. This reinforces their understanding of the structure and function of...

One cloning technique is somatic cell nuclear transfer (SCNT). Observe the process in action through an animated video. Review the applications of the process for both therapeutic cloning and cloning of an individual.

Teach your class how to get out of a cell — or break in. The third installment in a seven-part series introduces the class to cell membranes and their functions. The lesson plan includes information to present to the class,...

Learn about regeneration by working with planaria, a freshwater flatworm. Discover how long it takes for the flatworm to regenerate a head.

Students set up a simple way to indirectly observe and quantify the amount of respiration occurring in yeast-molasses cultures. Each student adds a small amount of baking yeast to a test tube filled with diluted molasses. A second,...
