Water Kit^©

Polarity is unforgettable after modeling with these engaging magnetic molecules. Students love figuring out molecular attractions and repulsions, providing a springboard to more complex chemistry concepts. When using this kit, students can:

• Investigate the polarity of water molecules
• Explore ionic, covalent, and hydrogen bonds
• Experiment with adhesion, cohesion, and capillary action
• Identify and model states of matter
• Demonstrate changes in volume between liquid and solid water
• Build different types of ice
• Simulate solubility with sodium and chloride ions
• Build ethane and ethanol to observe interactions with water

Considered the gateway kit for students to develop model literacy, this is a great beginning of the year activity. Rigorous and engaging materials that provoke and inspire invite all students to the learning.
