This engaging science lesson plan involves students working in pairs to explore the layers of the Earth and related concepts. Students will discuss and brainstorm answers to problems presented in a slide, using the Hide and Reply method for effective modeling. By recording answers on the whiteboard, the class can collaborate to understand geological principles such as plate motion and weathering processes. Reflection activities enhance their confidence and critical thinking about eliminating wrong choices and utilizing visual aids in answering questions.
E N D
Instructions • Place students in groups of two. • Give student pairs time to read and brainstorm possible solutions to each problem from the slide without answers. • Use timer or help students keep track of time (1-2 minutes per problem). • Go over the following sample question 1 with the entire class to model Hide and Reply procedure.
Hide and Reply method Teacher models with class Sample question 1 What are the layers of the earth? • Each pair comes up with all possible solutions for the sample question (1 minute). • Assign a students from each group to explain how they came up with their answers. • Record each groups’ answer on a white board.
