Insight 360™ is eInstruction’s classroom instruction system that allows you to interact with your students as they learn, quickly gaining insight into student understanding during class so you can adjust instruction in real-time during a single class session.

Use this content, designed specifically for use with Insight 360™, to interact with your class. This content includes brief instructional material and two types of activities:

Constructed Response Activity for students to complete as an individual or a group assignment. Send each Constructed Response Activity to the Insight 360 iPad Student App.

Assessment Item with CueTag™ for students to respond to via student response devices. Receive instant real-time feedback and longitudinal reports.

Periodic Table

  • The periodic table is a table of chemical elements arranged by atomic number.

Elements

  • Each table square includes the atomic number, element symbol, and atomic mass. Label these on the lines below.
  • Protons are positively charged and electrons are negatively charged. This creates a neutral charge for each element.

Chemical Symbols

Each chemical symbol is made up of one or two letters. As new elements are discovered, the person who discovered the element has the privilege of naming it. Name these chemical symbols.

F B

Au Mn

He S

F Fluorine B Boron

Au Gold MnManganese

He Helium S Sulfur

CaCalcium Al Aluminum

ClChlorine Na Sodium

O Oxygen Cu Copper

Cu stands for _____.

  • a. Copper
  • b. Chlorine
  • c. Curium
  • d. Carbon

Organization: Groups or Families

The elements in the periodic table are arranged in vertical columns called groups or families. Elements in a family share chemical properties.

Organization: Periods

The horizontal rows in the periodic table are called periods. Elements in a period contain very different properties.

The Periodic Table

Click the table to view a video on the periodic table.

You would expect Lithium (Li) and Carbon (C) to share some of the same chemical properties since they are elements in the same period.

  • True
  • False
