Abstract

---

The article shows educational experiments related to protein properties which could be easily adapted to any educational level, from primary to high school and even University. Furthermore, each of these experiments is about the most important properties of proteins such as stability, solubility, acid-base precipitation and both chemical and physical denaturalization. Moreover, these didactic practicals introduce four relevant techniques in chemistry such as isolation, purification, crystallization and osmosis. Therefore, through them, teachers could introduce diverse relevant concepts which are normally included in the curriculum of chemistry subject depend on the educational level. Additionally, all the educational experiments, described in this work, could be performed in both University and school laboratories because they only need common chemical compounds and basic materials. The main aim of the authors is to encourage science teachers to use these educational practices as pedagogical tools to consolidate and integrate the knowledge that students receive in theoretical classes.
