Unit Overview

Learners will begin by solving the mystery of the non-browning "sugar". In the video mystery and hands-on modeling activity, learners will discover that everything in our world is composed of small atoms, which, when bonded together, create unique structures with unique properties. Learners then select their own element and bring it to life by either creating a profile for it or designing a product based on it.

  • Lesson 1
    Lesson 1: Solve: Atomic Mystery + Vocabulary Mind Map

    Solve: Atomic Mystery + Vocabulary Mind Map

    Chef Crystal is feeling the heat! Learners help Mosa solve the mystery of why Chef Crystal’s award-winning cooking has suddenly gone sour. Utilizing new vocabulary and guided video questions, learners discover that substances that may look the same to the human eye can have very significant chemical and physical differences (80 minutes).

  • Lesson 2
    Lesson 2: Make: Atomic Modeling

    Make: Atomic Modeling

    Learners engage in the hands-on modeling activity of showing different atomic combinations, leading to different molecular properties (150 minutes)

  • Lesson 3
    Lesson 3: Lesson 3: The Engineer - Option 1

    Lesson 3: The Engineer - Option 1

    Choose from two options! 1. Students select an element from the Periodic Table, research its chemical and physical properties, and design a character from their element research OR 2. Students select an element or compound, research its chemical and physical properties, and design a new product or futuristic material. (150 minutes)

  • Next Generation Science Standards
    MS-PS1-1
    Develop models to describe the atomic composition of simple molecules and extended structures. [Clarification Statement: Emphasis is on developing models of molecules that vary in complexity. Examples of simple molecules could include ammonia and methanol. Examples of extended structures could include sodium chloride or diamonds. Examples of molecular level models could include drawings, 3D ball and stick structures, or computer representations showing different molecules with different types of atoms.] [Assessment Boundary: Assessment does not include valence electrons and bonding energy, discussing the ionic nature of subunits of complex structures, or a complete description of all individual atoms in a complex molecule or extended structure is not required.]
  • Inquiry Scale
    • Each lesson in the unit has an Inquiry Scale that provides directions on how to implement the lesson at the level that works best for you and your students.
    • “Level 1” is the most teacher-driven, and recommended for students in 4th-5th grades. “Level 4” is the most student-driven, and recommended for students in 7th-8th grades.
    • For differentiation within the same grade or class, use different inquiry levels for different groups of students who may require additional support or an extra challenge.
  • Common Misconceptions
    • Learners will often use the terms “atom” and “molecule” interchangeably, so emphasize the difference both in the video and the vocabulary map before proceeding to The Make.

    • Carbon Atoms are Great Dance Partners

      In this article, students learn about what makes carbon so special and why it easily bonds with all kind of different molecules. Through as analogy comparing them to dance partners, the basic ideas behind covalent bonds and electron sharing are explained.

    • If You Were Made of LEGOs

      Students should already know that we aren't all made up of LEGOs, but this article should help them understand that we're all made of matter, we all have mass and that mass is made up of tiny parts called atoms.

    • Drawing an Atom

      The concept of drawing things that are too small to see is tough! This article explains that protons and neutrons are located in the nucleus and electrons move around outside the center of the atom.

    • Atom + Atom = ?

      The tiny parts that make up the universe are constantly breaking and reconnecting. This article explains to students that atoms can combine into the compounds and molecules that make up everything in the universe.

    • Opposites Attract

      In this article, students read about the basics of what makes up an ionic bond. The article starts out with a simple description of electrons and follows by describing cations and anions before connecting the concepts as an ionic bond.

    • Carbon Based Life

      In this article, students read about why carbon-based life forms are all around us. They read about the strong bonds that carbon forms with other atoms and the backbone that carbon forms to create many thing that we depend on to live.
