Students are instructed in the procedure for removing the epithelial cells of an onion and staining with iodine. These cells are fairly easy to see and most beginning students will have no trouble locating the…

Investigation: Tools and Measurements
I designed this activity to help students become familiar with basic equipment found in the lab. Students take volume measurements using a graduated cylinder, beaker, and a 3ml pipette. Ultimately, they must determine how many single drops of water are in 1 milliliter by designing a way to test this given the tools provided.…

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…
