Each card has an image, Practical Job Role, Sound Bite with some sentence starters or questions, and Speaking Role to guide lab groups equally through an experiment. When working in smaller groups, multiple cards can be given to one student. Can be used to differentiate job roles for high and low students.
These cards have been blown up and used as posters in my classroom.
Print out and glue to card-stock and laminate for extended use. Add to lanyards for students to wear. Use a poster maker to create a large poster for each responsibility.
