Section 1
Elements Build All Matter From Atoms
Elements are substances made of only one type of matter and cannot be broken down further. Atoms are the smallest parts of elements, with each element containing identical atoms with unique properties.
In Grade 4 Science: A Closer Look, Chapter 5 Lesson 3, students learn to classify matter by identifying elements, atoms, metals, nonmetals, and metalloids using the periodic table. The lesson teaches students how to distinguish metals from nonmetals based on properties such as luster, ability to bend, and heat conductivity. Students also explore chemical symbols for elements and conduct hands-on investigations to test and classify unknown materials.

Section 2
Scientists Organize Elements in the Periodic Table
The periodic table arranges elements by atomic number. Elements in the same column or row share similar properties, helping scientists predict how unknown elements might behave.
Section 3
Properties Distinguish Metals From Non-metals
Metals shine, bend easily, and conduct heat well. Scientists test materials by examining luster, flexibility, and heat conductivity to classify them as metals, non-metals, or metalloids.
Section 4
Symbols Represent Elements in Scientific Communication
Scientists use shorthand symbols for elements, often using the first letter of the element's name or its Latin name. These symbols help organize the 112 known elements.
