Lesson Plan
Find the Missing Spy - A Periodic Table Activity by ECSDM
Subject
Math, Science & Technology, Science (NYS P-12)
Grade Levels
Intermediate, 8th Grade
Description
In the previous lessons of the unit, we have dealt with the atoms in order to set ourselves up to develop an idea of how we can classify these elements into an organizational chart, such as the periodic table. In this mini lab activity, students will develop an organization of the spy mug shot pictures into a readable and usable form that the students can use to identify a missing member of the spy family using the properties of their table. This will lead to a discussion of the development and set up of the Periodic Table of Elements.
Objectives
The learner will be able to
Cognitive
- Identify and describe the information on the periodic table.
- Compare the valence electrons in a family and a period.
- Explain how the number of valence electrons influences the properties of elements.
Affective
- Offer opinions as to how the pictures of people on the paper represent atoms.
- Communicate with teacher attentively.
Psychomotor
- Use and work with their table to locate properties and characteristics of the missing spy.
Materials/Web Resources
SMART Board, LCD projector, laptop computer, PowerPoint notes, SMART Notebook file with the missing spy pieces, spy activity packets, spy worksheet.
Procedure
Step-By-Step Procedure
Capture Attention and Motivate
- What do we know about atoms?
- How did we shorten the information so that it is easily read?
- How would you like to make that information even easier to read?
Terminology –
Activity
- Students will be given a mock spy activity in which the teacher will give them pictures of all the possible spies except for one. See attached for further instructions.
Collaboration –
- At the end of the time, the teacher will gather all the students and have them talk about how they found the correct picture.
- Teacher will talk about following patterns and determining what the last row might look like.
Mendeleev –
- This is how our modern periodic table was developed.
- Mendeleev wrote out everything he could about the elements he knew on cards, and tried to place them in patterns where it was appropriate.
- When he didn’t know an element, but felt there should be one there, he left a space, just like you did.
- Later scientists eventually discovered the elements he predicted by using the same method.
- Mendeleev ordered his table on many characteristics.
- What do you think were some of them?
- The most important was the atomic mass.
- Why is it called a periodic table?
- Because the pattern repeats over an over again.
Modern Periodic Table –
- In what way did Mendeleev order his table?
- How do we order it today?
- Why do we do that?
Closure –
- What are some other periodic tables that you know about?
- In what ways do you consider the patterns?
Assessment
Students will be handing in their completed lab form at the end of the period or by the time of the next class.
