Purpose

In this activity you will learn about how matter, atoms, and bonds are vital to life. All forms of life are made of matter. Matter is anything that occupies space and has mass. Atoms are the smallest piece of an element. Elements are substances that cannot be broken down and still retain their distinct chemical properties. When atoms chemically bond together through chemical reactions, they form molecules. Bonds form between atoms to achieve stability through being in the lowest energy state. Chemistry is all about how atoms behave and interact with each other. In order to understand why different kinds of atoms behave the way they do, we will have to know something about how these atoms are put together.

The videos below will discuss these ideas further. Please watch the videos and then follow the instructions below.

Instructions

As you watch the following four videos, take notes on anything you find interesting and helpful in expanding your understanding of the cell cycle. Add your notes to your Evidence Notebook. Now, let's explore how the process of sharing electrons can hold two atoms together.
- What Is An Atom And How Do We Know?
  In the first tutorial, we will take a look at the parts of the atom and learn about the properties of these atomic pieces.
- What Are Atoms Made Of?
  In the second tutorial, we'll look at how ions are formed, the forces that hold the ions together, and how the structure of the ionic compound relates to its formula.
- What Is a Molecule?
  In third tutorial, covalent bonding is typically explained as a bond that forms when atoms are sharing electrons.
- Chem Think (Interactive Experience)
  In this tutorial, we'll explore what this means and how the process of sharing electrons can hold two atoms together. Now use this information to complete the three following interactive experiences from Chem Think:
  Atomic Structure
  Ionic Bonding
  Covalent Bonding
As you watch, take notes on anything you find interesting and helpful in expanding your understanding of the cell cycle. Add your notes to your Evidence Notebook.
Answer the following question for activity 2.1.2 in your Lesson 2.1 Worksheet:

The purpose of this activity is to rank the above listed resources content that was most helpful in your understanding of this lesson's main ideas. Watch the above video links and arrange these four resources in order from most-relevant to least-relevant, following each with a sentence about their relevance and/or importance to you. Make sure that you account for content found in each of the resources.
