Course Plan: All Things Are Made Up of Atoms
Introduction
This Grade 7 Science course explores the fundamental concept that all matter is comprised of atoms. Throughout this course, students will journey through the world of atoms, learning about their structure, properties, and interactions. The goal is to provide a deep understanding of atomic theory, its historical context, and its relevance in everyday life. By the end of the course, students will foster critical thinking skills and a scientific mindset as they explore how atoms are the building blocks of everything around us.
Course Goals
- Understand the structure and components of an atom.
- Explain the significance of atoms in the composition of matter.
- Apply the concept of atoms to real-world scenarios and scientific phenomena.
- Develop lab skills to explore atomic properties through experimentation.
Course Aims
- To examine the historical development of atomic theory.
- To differentiate between elements, compounds, and mixtures.
- To introduce the periodic table and its organization.
- To analyze atomic interactions and basic chemical reactions.
