OJCS Science

This post will contain all of the grade 7 lessons on ecosystems. Students will be learning about the interactions within the environment, and identifying factors that affect the balance of an ecosystem. They will design and construct a model biosphere and use it to investigate interactions between components and how matter is cycled within the environment. Later in this section, students will describe the roles and interactions of producers within an ecosystem and distinguish between primary and secondary succession. We will begin by learning how to identify biotic and abiotic elements in ecosystems and describe the interactions between them.

Lesson 4: The Periodic Table of Elements

Some Key Concepts About Elements and their Atoms

• Atoms are made of extremely tiny particles called protons, neutrons, and electrons.
• Protons and neutrons are in the center of the atom, making up the nucleus.
• Electrons surround the nucleus.
• Protons have a positive charge.
• Electrons have a negative charge.
• The charge on the proton and electron are exactly the same size but opposite.
• Neutrons have no charge.
• Since opposite charges attract, protons and electrons attract each other.
