Sugar Lesson Plan For Periodic-Table Activity:

Age / grade-level : 14 - 15 yrs/ 9

What Is the Periodic Table Activity?

Periodic-Table is a Sugar Activity.(See https://github.com/sugarlabs/periodic-table)

It contains information about the elements in the Periodic Table; it also includes recently added elements by IUPAC — nihonium, moscovium, tennessine, and oganesson.

Skills:Using this, Students will come to know about the different types of elements and compounds and their properties.

Learning Objectives:

1. Names and nature of different elements.
2. Difference between IUPAC naming and common names.
3. The properties on the basis of which the elements differ from each other.
4. Practical use of periodic table.

Lesson Flow:

1. Introduction Of Periodic Table (30 Mins):

• Tell them about the discovery of the Periodic Table.
• Discuss the importance of Periodic Table.
• Discuss how did scientists organize the elements before the modern Periodic Table

2. Introduction to Periodic Table Activity (1 Hr):

• Let students get their hands on the activity.

How does activity work?

You can click on any element and see its chemical and physical properties.Students can explore lanthanides, metalloids etc.

Instructional sequence (1–2 hrs):

1. Each student will give a short presentation on an element from the Periodic Table.The presentation should include the element’s mass, electronegativity, electronic radius and where it is used in daily life.

• It will boosts the student’s confidence and allow them to improve their communication skills .

2. Conduct a random group quiz in class.

• Which will help the students to give on-the-spot answers.

By the end of the lesson students will came to know about the electronic configuration of different elements, how electrons are filled in sub-shells,how different elements participate in different reactions, what are their common structures etc.

Fun Activities And Questions: (1–1.5 hr)

• Ask students that what will happen if we exchange the places of the elements in the table.
• Ask them to learn the Periodic Table upto 20–30 atomic mass no.
• Let them explain what does each letter or no. represent in each block of an element.
• They can play a game like “Geography” where they only have to use the name of the elements.
• Ask students why the radius of noble gases are much lower as compared to the elements of the same row even though while moving left to right in a row, the radius of atom decreases.
• Ask which group is known as coinage group?
• Ask student to explain the concept of radioactivity and radioactive elements.
• Ask student why atomic no. is the base of the modern periodic table and not the atomic mass?
• For fun, you can go this link https://www.uky.edu/Projects/Chemcomics/

Assessment: (1 hr)

• At the end of the lesson, students can cross question each other based on elements, compounds, reactions etc.
• Students can challenge the optimisation and arrangement of the current Periodic Table.
