SC.8.P.8.6

Recognize that elements are grouped in the periodic table according to similarities of their properties.
General Information
Subject Area: Science
Grade: 8
Body of Knowledge: Physical Science
Idea: Level 1: Recall
Big Idea: Properties of Matter - A. All objects and substances in the world are made of matter. Matter has two fundamental properties: matter takes up space and matter has mass which gives it inertia.

B. Objects and substances can be classified by their physical and chemical properties. Mass is the amount of matter (or "stuff") in an object. Weight, on the other hand, is the measure of force of attraction (gravitational force) between an object and Earth.

The concepts of mass and weight are complicated and potentially confusing to elementary students. Hence, the more familiar term of "weight" is recommended for use to stand for both mass and weight in grades K-5. By grades 6-8, students are expected to understand the distinction between mass and weight, and use them appropriately.

Clarification for grades K-2: The use of the more familiar term ‘weight’ instead of the term “mass” is recommended for grades K-2.

Clarification for grades 3-5: In grade 3, introduce the term mass as compared to the term weight. In grade 4, investigate the concept of weight versus mass of objects. In grade 5, discuss why mass (not weight) is used to compare properties of solids, liquids and gases.

Educational Game

The Element Game:

The computer will randomly pick an element and present the student with that element's data from the Periodic Table of Elements. They will use that information to answer the question that the computer asks about the number of protons, neutrons, electrons or nucleons (particles in the nucleus) that an atom of that element contains.

Type: Educational Game

Lesson Plans

Atomic Structure Unit: Lesson 3 - What's My Element?:

This is the final lesson 3 in the Atom Structure Unit. This lesson allows students to program in Scratch and switch the costumes based on the operational conditions placed on the sprite. The final product in this lesson will showcase the students' conceptual understanding of the atomic structure in a computer science medium.

Type: Lesson Plan

Atomic Structure Unit: Lesson 2 - Build Atom in Scratch:

This is lesson 2 of 3 in the Atomic Structure unit. This lesson helps students sketch atoms by placing electrons, neutrons, and protons by referring to the periodic table. This lesson also helps students upload/draw costumes on Scratch to create animated objects.

Type: Lesson Plan

Atomic Structure Unit: Lesson 1 - Science of an Atom:

This is lesson 1 of 3 in the Atomic Structure unit. This lesson helps students determine charge, structure and location of different components of an atom. This lesson also allows students to sketch the first 18 elements from the periodic table.

Type: Lesson Plan

Periodic Table - Atoms and Bonding:

In this Model Eliciting Activity (MEA), students will use their knowledge of the organization of the periodic table and the basic properties of atoms to determine which elements should be used to develop compounds with two atoms of different elements. Students must determine the number of protons, neutrons, and electrons in a neutrally charged atom of an element using the periodic table. They must also determine which elements will likely bond together using their location on the periodic table. Students completing this MEA will develop two short essay responses to a client in the scientific industry.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.

Investigating Elements - Metals, Non-Metals, and Metalloids:

This resource is a guided inquiry that will aid students in understanding how an element's physical and chemical properties determine its placement on the periodic table.

Type: Lesson Plan

Musical Elements:

This resource is a research project that is part of a unit on atomic structure, the periodic table, and chemical bonding. Students form a group (band) and are assigned a part of the periodic table to research. They will discover why the periodic table is arranged the way it is and properties of different sections of the periodic table. Each group of students will create a band show poster that relates to properties of elements in their assigned section of the periodic table. Each individual student will also make a Facebook-type page that describes the properties and uses of a particular element in their "band."

Type: Lesson Plan

Element Most Wanted Poster:

Students will research an element from the Periodic Table of Elements and produce a Most Wanted poster allowing students to creatively detail the chemical and physical properties of a particular element.

Type: Lesson Plan

Last...but certainly not the least:

Through this activity, students will create a periodic table with Electron Dot Diagrams. This investigation allows students to explore and recognize patterns of the periodic table. This lesson allows students to draw conclusions and clearly demonstrates that atoms of elements in the same group have the same number of valence electrons while sharing similar properties and characteristics.

Type: Lesson Plan

Periodic Table Family Album:

Mendeleev created the first periodic table based on atomic weight. He observed that many elements had similar properties, and that they occur periodically.

The periodic table can be divided into families of elements, each having similar properties.

Type: Lesson Plan

Similarities of Elements:

This lesson explores elements and classification within the periodic table.
