Cell Signaling – Comprehensive Unit Plan
Cell signaling is the process by which cells communicate with each other and respond to external stimuli, ensuring the coordination of vital biological functions. This system involves a signal binding to a receptor on a target cell, and triggering a series of intracellular events. These signaling pathways often include second messengers, protein kinases, and phosphorylation…

Practice Feedback Loops of the Endocrine System
This exercise shows three feedback loops of the endocrine system where students complete the diagram. Focus is on insulin, antidiuretic hormone, and calcitonin.

How is Glucose Taken Up by Cells?
This worksheet takes a closer look at the cell membrane and how insulin binds to the receptor on the cell membrane which creates a signal cascade, resulting in the movement of the Glut-4 transport protein to the surface of the cell. Students interpret a graphic showing the membrane, receptors, and the Glut-4 transport protein.

DNA, Proteins, and Mutations
Students explore how DNA becomes a function protein by using a codon chart to transcribe and translate a gene. They compare the gene found in humans to that found in other animals, deducing that the genes are very similar with only slight changes. Finally, students examine the different types of mutations and how a…

Feedback Loops: Insulin and Glucagon
The Next Generation Science Standards includes feedback loops and homeostasis as a standard for life science. While homeostasis is a theme for many units in biology, feedback mechanisms are fairly specific. In fact, this is probably the most oddly specific topic found in NGSS. If you are trying to include it, most younger students…
