PBL

View On FunnelBrain»



This unit will continue the PBL from the previous unit. The students will eventually use thier resumes to locate a good bonding partner in the class. Once they have made thier selection, they will complete an activity sheet which allows them to explain how and why they selected their partner.

2. Find Your Work Partner”
>>This activity is the conclusion of the PBL from the previous unit. The students are to take the resume they wrote in the last unit and use that to find another “element” on the class with whom they can “work” or bond to make a compound. When they have located such a partner, then they should complete the associated worksheet.
