Water is essential to life. This collection provides models of water to help students become familiar with the many properties of water that make it such an important molecule.
With this collection, students can:
- See spontaneous hydrogen bonding
- Compare hydrogen bonds to ionic and covalent bonds
- Make ice crystals
- Dissolve salt (hydration shells)
- Evaporate water (water cycle)
- Compare how ethane and ethanol interact with water (polar – non-polar interactions)
- Explore capillary action
