This document outlines the steps for a science lesson on the periodic table. It includes: 1. Dividing students into groups and assigning roles for material manager, secretary, reporter, and observers. 2. Defining key terms like family, period, representative elements, and noble gases. 3. Having students explore the periodic table through different stations, like creating a timeline or song about its development. 4. Explaining the outputs and relating the periodic table to students' lives through sayings like "birds of a feather flock together." 5. Evaluating learning through a symbol matching game where students identify elements and their properties to earn points.

A. House Rules in the Laboratory
1. You will be divided into 4 groups
2. Each group should have the following focal persons;

b. Secretary
c. Reporter
d. Observers
1. Observe time allotted for the activities you are given 15 minutes to perform the activity
2. One of the observers will report their group output for 3 minutes.

7. Defining Terms
1. Family or Group- An arrangement of the elements from top to
bottom in a column.
2. Period or Series –arrangement of the elements from left to right
in a row
3. Representative Elements- These are the elements in the A family
4. Transition Metals- These are the elements in the B Family
5. Noble Gases- these are the elements in family 8A which are non-
reactive

Let us Listen to the Resource Speaker

9. Explore
Station 1.- Healthy minds
Create a Time line showing the
development of the periodic table.
In the form of spoken poetry or rap.

10. Explore
Station 2- musicians
Compose and perform a song involving
the elents in the periodic table using the
tune of BAHAY KUBO.

11. Explore
Station 3- Ewi Grocery store
The food stuff in the grocery store shows the recommended
daily requirements or nutritional facts at the back of the food
products. Identify the elements present in the every food
product by writing in a meta card. Include also the
composition of some utensils or material in your grocery store.

12. Explore
Station IV- Make me Beautiful
Color all elements belonging to the same family
with 1 specific color
Make an outline in every period of the
elements with 1 specific color per period
Make a black outline on the noble gases that
separates the metal and the non metals.

13. Explain
Present Your Outputs

14. Extend
How will you relate this adage to your real life
with respect to the periodic table.
Tell me who your friends are and I will Tell you who you
are.
Or
Birds of the Same Feather Flocks Together

15. Evaluate
Game: Symbo Game
1. Secure 2 symbo card per students
2. using any marker mark the elements that is being drawn in your
symbol card.
3. The student who will be forming a strait or diagonal pattern first,
will be declared as the winner.
4. An additional point of 10 points will be given to the winner.
5. If the student can read the symbols of the element in the
winning pattern and identify its period and family will be given
another bonus point of 10 points.
