Objective of the Learning Engagement: The objective of this learning engagement was to help students understand the evolution of atomic models (Dalton's, Thomson's, Rutherford's, and Bohr's) and reinforce their conceptual clarity through creative, hands-on model-making using everyday materials. It also aimed to foster collaboration, communication, and analytical skills. Details of the Learning Engagement: Date of Activity: 16th September 2024 This was a group activity where grade 9 Chemistry students were divided into teams, with each group assigned one of the four atomic models: Dalton's, Thomson's, Rutherford's, or Bohr's. Each group was tasked with: 1. Researching their assigned atomic model to understand its features, scientific basis, and limitations. 2. Designing a physical model using available materials like paper, clay, or objects from their surroundings to represent the structure and characteristics of the model. 3. Highlighting key features of...
Objective of the Learning Engagement: The objective of this activity is to help students understand and differentiate between elements, compounds, and mixtures through interactive and hands-on approaches. By creating and analyzing physical models using colored clay and participating in a role-play activity, students can visualize molecular structures, embody atomic interactions, and engage with abstract chemical concepts in a tangible and meaningful way, fostering deeper comprehension and retention. Details of the Learning Engagement: Project Task given: Students were assigned a task to create a 3D molecular model set using coloured clay balls to represent elements, compounds, and mixtures. Students worked in groups to construct and classify examples of each. Students will document their observations and reasoning for classifying models as elements, compounds, or mixtures in the provided reflection sheet. Analogical Connection: Students worked in groups to create 3D molecular models us...
