Start the session with the question:
What is the materials and what are the characteristics of these materials.
What is the following: Glass, Metal, Plastic, and Rubber?
Where can we find these materials? (Students will give examples of where they find the glass material for example)
What are the differences between them? (Students should talk about the different forms these materials has and different functions)
Let the students discuss the following questions together, let them write any question they want to discover during the material lesson, and stick them to a wonder wall so they would remember to figure out their question through the process.
Let them share with others what they know about these questions and from where did they know about it. (This might let students remember that they broke a glass cup last week so they would know that glass is breakable, and link their life to the classroom).
Share your stories if you have any about the materials, did you break anything, did you try to bend iron and you failed, did you ever play with rubber and wonder how would that go so big without breaking?
2 Direct Instruction
Teacher will introduce the vocabulary, let the students give ideas of what might they mean and how would that relate to the materials understudy. (The vocabularies are: Breakable, Can bend, Resistible, Irresistible, Elastic…)
Print out the vocabulary that you want them to know, and let them see these words during all time; this will help them learn the terminology and remember to use it during their writings. Then they might like to add the definition of each terminology.
Allow the students to draw a picture that represent the word and stick it to the wall
3 Guided Practise
Students are asked to go to the computer lab, and enter the URL and discover the materials where they act like scientist to discover new Knowledge from their observations. They will discover and reach answers for their questions.
If its your first time to take the students to the computer lab, tell the students what they are going to do, and the importance for them to follow the directions to finish on time.
Write the instruction of what the students should do, so they will follow and be able to access the website (Example, I write the steps to my students to follow, 1- turn on the computer 2- open the browser, 3- insert the following URL, 4- discover, 5- answer the questions)
If you don’t have access to computer lab, you can use the BBC URL and let the students discover the materials together during the class using either a projector or interactive board if available.
You may want them to work together to built their collaborative skills.
4 Independent Practise
Solve the Riddles
After they experiment with materials, each group of students have to answer a riddle, where they should find the best materials to following scenario. It is better to let the students work together to discuses the answer.
Riddle 1: what would be the best way to save jam for a year? Why do you think this would be the best material to use?
Riddle 2: What would we use if some one were drowning in see? Why do you think this would be the best material to use?
Riddle 3: What is the best way to build a car? Why do you think this would be the best material to use?
Students shall sit in small groups (of 2 or 3) to answer the questions, if you have a bigger class give the same riddle to 2 or 3 groups so we might get different answers to the same riddle and students would see there is different solutions for the same problem.
5 Wrap Up
Each group of student will share their riddles answers to the whole class, and each student will reflect on their colleagues’ riddles on padlet.
Finally, use padlet to do their exist card.
Using the padlet as exist card will allow students to reflect on their learning process and would let them think of how would they be better
