Go Green: Reduce, Re-use, Recycle, and Re-design a Plastic Grocery Bag

Go Green! 

4 R’s: Reduce, Reuse, Recycle, and Redesign Grocery Bags! 

Grade: 2 

Timeframe: 4 Weeks


Overview of Unit

This is a STEM unit that can be used in conjunction with ITEEA EbD TEEMS Grade 2 Our Environment, Our Health Unit. Further, teachers might want to use this STEM Unit with environmental units and Earth Day. Students learn about their positive and negative impact on their environment. Students learn that they can have a positive impact on their environment when they use the 4 R’s: Reduce, Reuse, Recycle, and Redesign process. 


Stage 1 - Desired Results

Big Idea(s)
 We can create products that can positively improve our environment and the way we live. We can create a positive impact on our environment when we use the 4 R’s: Reduce, Reuse, Recycle, and Redesign process. Technology can be created and/or modified using the design process.

● Slide 5: The Google Expedition Tours have scripts with information about trash and pollution. Click on the hyperlink to view the explore the Expedition.
   ○ Google Expedition Tour: What happens to your trash and recyclables?
   ○ Students have the opportunity to look at trash in New York’s Staten Island. Students have the opportunity to see how some people do not recycle things that we could have recycled.
   ○ Further, students will have the opportunity to observe how different electronics could have been reused instead of being thrown away.
