Reflection: Connection to Prior Knowledge Pollution Lab Stations - Section 4: Water Purification Lab Station

 

Each student is going to connect to different prior knowledge and experiences of the world when identifying consequences of technologies. One important thing to do after these labs is to have groups share their advantages and disadvantages with each other.

Make sure that students hear ideas from students with different outlooks than them. I find in evaluating these technologies that each student thinks uniquely about the consequences in the world. For example, some students explain that the technology would be good thing because it would provide jobs for people, while others note that the benefit is that it could end sickness in third world countries that have dirty water. Each student brings their own social awareness to the table and they can open up other student's eyes to consequences and advantages they never would have considered otherwise.
