These lessons focus on what a heterogenous emulsion is, the first was based on theory and the second was on an experiment – focusing on forming hypotheses and responding to them.
Day One:
- Read through an article outlining the difference between emulsions and colloids
- An emulsion is where one substance is evenly distributed (small droplets) in another substance – both are liquids
- Answer true and false questions in pairs, to discuss and bounce understanding off each other
- Answer long form questions alone and then discuss as a class
- Record hypotheses for what they believe will happen when mixing egg, water, and vinegar
Day Two:
- Begin by grouping students
- Each group collected materials and returned to their groups, making observations, and following procedure – mixing oil and water, then mixing in egg
- Students made conclusions that responded directly to their hypotheses
Core Competencies: Critical Thinking
Facet: They reflect on and assess their experiences, thinking, learning processes, work, and progress in relation to their purposes.
Profile: I can ask questions, make predictions, and use my senses to gather information.
