Material Match-Up: Prepare a set of cards with pictures or descriptions of processed materials (e.g., plastic, paper, glass, metal) and their corresponding natural materials (e.g., oil, trees, sand, ores). Divide the students into pairs or small groups and distribute the cards. The students must match each processed material with its natural material and explain the connection.

Material Scavenger Hunt: Create a scavenger hunt where students have to find examples of processed materials in their surroundings and identify the natural materials they originated from. Provide a list of processed materials (e.g., plastic bottle, aluminum can, cardboard box) and ask the students to take pictures or bring in samples of these items along with the natural materials they are made from.

Material Sorting Game: Collect a variety of objects made from different materials (e.g., cotton shirt, wooden pencil, glass jar, rubber ball) and place them in a box. Divide the students into teams and give each team a sorting mat with categories such as “natural materials” and “processed materials.” The teams must take turns picking an object from the box, discussing as a group whether it is a natural or processed material, and placing it on the correct category on their sorting mat.

Material Investigation Stations: Set up different stations around the classroom or outdoor area, each representing a different processed material (e.g., plastic, paper, metal). At each station, provide samples of the processed material and its corresponding natural material. Students can rotate through the stations, examine the materials, and complete a worksheet or journal entry where they describe the similarities and differences between the processed and natural materials.

Material Art Project: Engage students in a creative activity where they use processed materials to create artwork that represents the natural materials they originated from. For example, students can use recycled paper to make a collage of trees or use plastic bottles to create a sculpture of an oil well. Encourage students to think about the connection between the processed material they are using and the natural material it came from while working on their art projects.
