Separation of Substances - Lesson 6

Lesson 6 -The Review Phase

 (6.1)Student Reflection and Evaluation:
One lesson after the end of the project will be dedicated to student reflection and evaluation. Their reflection will cover: what topics I learned about, what new skills I learned, what I liked about the project, what I didn’t like about the project and what I would do differently on the next project. An evaluation form will be completed by each student as a homework assignment.
A subsequent lesson will be used to discuss the observations made by the students.
(6.2) Teacher Reflection and Evaluation:
I have prepared a teacher reflection and evaluation form to complete that covers:
  • Successes : We have completed the project effectively with the help , advice and motivation of the incharge teacher Mrs.A C Santhamma
  • Challenges : Nowadays readymade cooking materials are available and majority of the ladies are busy with their works , so less chances of using the different methods of separation .
  • Achievement of project goals :Methods of separation like filtration , evaporation ,condensation etc. used in our day to day life.
  • What I learned : Different methods of separation that I can apply in my daily life.
  • What I would do differently next time : I would like to select a place in rural area and study about these methods more .
