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…

Case Study – What’s Wrong with Timothy?
The endocrine system can be a difficult subject to cover in anatomy. It isn’t as showy as the other systems where you can label organs or dissect an eyeball. Students must also memorize a number of hormones and their functions which have complicated names like thyroxine and tri-iodothyronine. When I first started teaching anatomy,…
