Features 23 core lab activities that cover the fundamental concepts of Force & Motion, Energy Transfer, Electricity & Circuits, Fluids and more.
Observing Phase Changes
Use a temperature sensor to measure the change in temperature during the heating of two different mixes of ice and water – one with distilled water only and one with salt dissolved in distilled water.
In this activity, students investigate the effect of solid-liquid transitions on the temperature of ice water solutions. They also:
- Learn that energy is a property of many substances and is associated with heat, light, electricity, mechanical motion, and the nature of a chemical
- Observe effects and changes in the characteristic properties of water such as freezing point and density
Students gain experience conducting the following procedures:
- Setting up the equipment and work area to measure the change in temperature during the heating of two different mixes of ice and water – one with distilled water only and one with salt dissolved in distilled water
- Heating an ice and water mix until all the ice has melted
- Comparing the temperature versus time graphs of melting for the two mixes
- Using math and critical thinking skills to compare and analyze melting points
Sensors / Equipment Used:
Allows students to measure Temperature, pH/ISE/ORP, Absolute Pressure & Voltage in one sensor. For use with PASPORT Interfaces.
