How would you introduce the lesson when you are teaching about solid materials in grade 4?which question would you ask in order to activate the learners prior knowledge without telling or showing them the topic.

To introduce the lesson on solid materials in grade 4, I would start by asking the students to think about the different objects and materials they interact with on a daily basis. I would ask them to consider the things around them that are not liquid or gas, and prompt them to think about what characteristics define these solid materials.

One question I would ask to activate the learners' prior knowledge without revealing the topic is: "Can you think of an object that you can hold in your hand and that retains its shape no matter how you move it or squeeze it?" This question will encourage students to think about the properties of solid materials without explicitly stating the topic of the lesson.
