Hank brings us another simple experiment that demonstrates the important biochemical process of osmosis by turning a chicken egg into a frightening alien-loo. No special lab kit materials are required to complete this lab exercise part a, resting pulse rate: negative feedback control and normal range homeostasis is maintained by negative feedback mechanisms that are far more complex than those involved in maintaining say house temperature as our example in lecture.

They design an experiment to test which conditions could lead to egg albumen protein (egg whites) to denature, and relate their proteins and homeostasis: designing an experiment preview. We concluded the egg lab with one final day of data collection after students turned in the quiz they received yesterday, they had the opportunity to measure the mass of their egg one last time before making final observations.
The egg lab above can be done at home using different liquids students would have to explain why the differences in the size of the eggs to their parents and how this might relate to the conditions needed for proper hatching in precocial birds (chickens and ducks). The minds-on, hands-on activity homeostasis and negative feedback – concepts and breathing experiments begins with analysis and discussion questions that develop student understanding of homeostasis and negative feedback, the difference between negative and positive feedback, and the cooperation between the respiratory and circulatory sys. I designed this lab activity handout so that my students could share the same lab experience that i did the printout will include a detailed description/checklist on what your students can do to investigate the movement of water through a selectively permeable membrane of an egg.
