Dear Volunteer Teacher,

The answer to science learning is student talk.
Getting learners to talk through concepts, practices, and understandings have the greatest impact on their science learning.
Busting myths, scientific knowledge building, reflective toss and evaluation forms a part of the science teaching process

  • Busting Myths: Help students bust the myth connected to the chapter . For eg Acids are stronger than bases. Acids are not found at home etc, through a simple question answer method/ video viewing etc and back up with an exercise to reinforce the correct learning.
  • Scientific knowledge building: Direct instruction by the teacher through use of aids and a check for understanding through questioning
  • Reflective toss: Put up a question for the day and have students work on it. For eg. Make a table and classify the following into acids and bases.
  • Evaluation: A set of 5- 6 questions that could be one word answers, T/F , label diagram etc
