And Now, What Do You Know About Microbes?

This activity is matched to the unit pre-assessment. It provides an opportunity for you, the teacher, to gauge students’ learning over the course of the unit. It also allows students to evaluate their own learning by examining their concept maps and responses to the pre-assessment. 


Procedure
Session 1

1. If you recorded questions from Activity 1 at the beginning of this unit, review each question with the class. Ask, Can you answer any of the questions now? Discuss students’ responses. 

2. Next, have students work in their original groups to review the concept maps started in Activity 1 and used throughout the unit. Each group should discuss the additions made to its concept map and decide which findings were most important. 

3. Ask each group to appoint a spokesperson. Call on each group and ask the spokesperson to explain one concept on the group’s map. Do this two or more times, in round-robin fashion among the groups, until most major concepts have been covered. 

4. Create a class concept map using the information presented. 


Session 2

1. On the following day, give each student a copy of the post-assessment. Students should complete it individually. 

2. After students have completed the post-assessment, distribute the pre-assessments. Have students compare their answers on both assessments so they can see how much they have learned during the unit. Discuss any remaining student questions and collect the assessments, which can become part of students’ portfolios or can be placed in their science notebooks.
