DNA, the Awesome Thread of Life

Biotech engineers discover that changes in the DNA code for cell wall formation can help create crops better suited for biofuel production. They extract DNA from wheat germ. They decode paper strips with codes and relate the activity to...

Three steps are needed to extract DNA from learners' inner cheek cells. The procedure and reasons for each step are explained. As enzymes work on the cells, a series of questions are answered regarding the structure of the DNA molecule....

Engage young biologists in exploring the mysteries of life with this collection of hands-on activities. Enlisting the help of numerous digital resources, students get an up-close look at the structure of plant and animal...

As an anticipatory set, biologists listen to the story of Ruth Patrick, a scientist who used algae to detect water quality. They observe a demonstration of osmosis and diffusion. In their lab groups, they place Elodea stalks in...

Some basic descriptions of DNA and the appearance of structures in a bacteria are included along with great diagrams.  The presentation has clear, but detailed slides, and your students will find the information about Gram staining...

Humans have taken communication to every corner of the Earth, yet our bodies, at the cellular level, have communicated without technology for millions of years. Learners view the variety of ways cells can communicate, whether right...

Explore the structure of cell membranes including cholesterol, glycolipids, glycoproteins, phospholipids, and proteins. The video shows and discusses the fluid mosaic model as well as how cell walls differ from cell membranes. 

Take a close up look at the replication of DNA and protein synthesis with this animated clip. The process is described in detail for your biologists. Utilize technology in order to see the inner workings of the cell.

The differences between prokaryotic and eukaryotic cells are explained and the parts of each are highlighted. Discover the major organelles found in an animal cell and each of their functions. Paul Andersen does an excellent job once...

Cell membranes and the factors that affect its integrity are studied, with Beet tissue used as the model. A poster to display findings of the permeability of the membranes would clarify understanding and also allow a layer of language...
