Featured in PASCO’s Elementary School Science Teacher Guide
Features 29 inquiry based labs designed for elementary students and coordinated with the standards for life, earth and physical sciences.
Freezing & Melting Water
Use a temperature sensor to measure the temperature of water in different forms and to learn that water can exist in different forms an can be changed from one form to another by heating or cooling.
To understand this content, students:
- Measure the temperature of their hand and the temperature of an ice cube.
- Allow ice to melt in their hand and explain that heat from their hand caused the ice to melt.
- Measure the temperature of a rock salt-ice bath and room temperature water.
- Freeze room temperature water by placing it in a rock salt-ice bath.
Sensors / Equipment Used:
Allows students to conduct all three measurements simultaneously and continuously. For use with PASPORT Interfaces.
