Success Criteria:

1. I can state that different materials have different properties.

2. I can identify materials that are suitable to build a house.

Aims:	Target Language:	Materials:
Aims: Students will answer the question, “What are the properties of materials?” with, “Flexibility, Hardness, Strength, Buoyancy, Transparency, Water resistance.” Students will answer the question, “What materials are suitable to use to build a strong house?” with, “(Material) can use to build a strong house.” Students will create and design a house that can withstand the wind.

Duration of Activity	Total time spent	Activities	Interaction Pattern
5 min	5 min	Welcome Students Greet students, set up classroom management system Introduce classroom rules, sing Hello Song. Have students ask and answer each other, “How are you?”"	S-S
10 min	15 min	Engage Show Presentation slides - The Three Little Pigs, which shows the students illustrations of the three little pigs building their houses. Simply tell the story of “The Three Little Pigs” to students. Have the students look at the materials used by the three little pigs to build their houses. Have students discuss and guess which house will collapse or down when the bad wolf blows the house. Ask the students the following questions: “Which house do you think will collapse when the bad wolf blows the house” Ans: “House A and C” “Why can’t the bad wolf blow house B down?” Ans: “House B is made of bricks.” Guide them to think about the material they think is needed to build a strong house. Ask the students consider linking this to different weather conditions: “What would you need if you live in a windy climate? A hot climate? A snowy and cold climate?”	T-S
5 min	20 min	Explain I Explain that materials are the matter or substance that objects are made from. Show the flashcards and explain that different materials have different properties, such as flexibility, strength, hardness, buoyancy, transparency, and water resistance. Flexibility: Able to bend without breaking. Strength: The material can withstand tension and strain. Hardness: The ability to resist the material to scratching, abrasion or cutting. Buoyancy: The ability to float. Transparency: Allow light to travel through and you can see completely through. Water resistance: Resistant to water and being wet. Tell students that understanding the properties of materials is important when creating something new (product). Let students know that selecting and combining the correct different materials to make something can prevent objects from collapsing or breaking.	T-S
10 min	30 min	Explore Using the flashcards from the explain I activity, place the flashcards on the table or floor into six groups. Ask the students to explore and look around the classroom to find some objects that are made of materials which have those properties (flexibility, strength, hardness, buoyancy, transparency, and water resistance) Ask students to sort and place the objects on the flashcard based on the properties of the materials of the objects. For example: Spectacles are placed on the “Transparency” flashcard. / Rubber band is placed on the “Flexibility” flashcard.	S-T
10 min	40 min	Explain II Launch the learning story: Ask the students to recall from the previous activity about the six properties of material. Pause the video and ask the students to discuss and group the objects correctly according to their properties. Explain that different materials have different properties and that certain materials are more suitable for completing certain tasks.	T-S
5 min	45 min	Break
5 min	50 min	Recap Review the flashcards - [Properties of Materials] Using the flashcards, the students need to explain the meaning of the properties, and give some examples (objects/materials) of the properties.	T-S
20 min	70 min	Elaborate Students can now explore their lab-in-a-box Ask students to recall the Three Little Pigs story - about the materials they used to build their houses. Divide the class into three groups. (Or they can work individually) Get the students to design and build a strong house that the bad wolf can't blow down. Step 1: Your house must be built on the provided foundation (must be at the bottom of the house) and using the roof (must be at the top of the house) provided. Step 2: You can only use the materials provided to your team. Step 3: Everyone must work together and all ideas need to be considered. Step 4: You only have 15 minutes to build your house and have it tested. After 15 minutes, students must bring their house to the “testing zone.” If the house is still standing after 20 seconds, it is a success! Note to Teacher: Houses can face any direction, but the wind must always come from the same place. Prepare a portable fan that can be used to “blow” the houses "What materials have you used to create your house?" "Was your house able to withstand the wind?"	T-S
10 min	80 min	Evaluate: Have the students show their “houses”. Elicit from the elaborate activity, discuss and ask the students: “Which material worked the best?” “Why do you think some materials were more effective than others?” “Was your house able to withstand the wind of the fan/big bad wolf?” “How could you improve your design?”	S-T
5 min	85 min	Wrap-up routine.

Reflection Questions:
What are the properties of materials? Some common mechanical and physical properties will provide information that product designers could consider in selecting materials for a given application. Some of the common properties of materials include flexibility, strength, hardness, buoyancy, water resistance, transparency and thermal conductivity."
The 3 Little Engineer Pigs 1. How can you keep the 3 little pigs safe from the Big Bad Wolf and the ever-changing environment? The 3 little engineer pigs were each tasked to build a house made of either bricks, cardboard or glass. Look at the different houses built by the pigs! Circle the icons below that you think the houses can protect the pigs from. 1. Glass house 2. Cardboard house 3. Brick house"

The 3 Little Engineer Pigs

1. How can you keep the 3 little pigs safe from the Big Bad Wolf and the ever-changing environment?
The 3 little engineer pigs were each tasked to build a house made of either bricks, cardboard or glass. Look at the different houses built by the pigs!
Circle the icons below that you think the houses can protect the pigs from.

Challenge 1:
For each item, write two words to describe the properties that make it work for this purpose. 1. strong 2. smooth 3. soft 4. bouncy 5. flexible 6. see-through 7. warm 8. rigid 9. light-weight 10. glass window 11. rubber ball 12. wool sweater 13. wood table 14. steel spring

THINK!
Based on the results of the experiment, answer the following questions: 1. What difference did you observe if the house is built from different materials? 2. Which material is more suitable to build the house? 3. What other materials do you think will be suitable to make a house? What are the properties of these materials?

SUMMARY
1. Different materials have different characteristics or properties, which make them suitable for different uses. 2. It is important for scientists to select the best materials to suit various objects and tasks. This also helps engineers create new materials for new products and technological devices.

Checklist
Once you are able to do what is stated, tick the boxes. 1. I can state that different materials have different properties. 2. I can identify materials that are suitable to build a house.
