Plastic-Eating Microbes to the Rescue!

Not all heroes wear capes... nor are they all "larger than life." 

They may in fact be microscopic... and they maybe bit-sized bacteria. Bioengineered to eat their way through problems, these mini-sized superheroes are environmental problem solvers.... designed to digest plastic waste!

In an innovative twist, there is a growing field of science dedicated to the microscopic solution to a major problem: plastic pollution. Scientists are working to "genetically train" minuscule bacteria (called microbes) to break down PET plastic, which is the plastic used in soda bottles, clam-shell style plastic food containers, and synthetic fibered fabrics. 

Yes, it sounds more like science-fiction than science. 

But it is not new, and dates back to over two decades:

• In 2001, Japanese scientists led by Kohei Oda discovered a collection of bacteria at a garbage area that were degrading plastic. "Eating" it, if you will. As they consumed this plastic trash, it led to the bacteria to grow and multiply. 
• Scientific research over time led to the 2016 discovery by Kohei Oda and Kazumi Hiraga that the microbe Ideonella sakaiensis' enzymes could break down PET plastic. This in turn served as energy for the microbes.

Working in labs through research like this, scientists have discovered that they could help fast-track this process through genetic engineering. This "superpower" of science, combined with technology, helps speed up the process, helping to power through the plastic pollution problem. Of course, "speeding up" is all relative as it is currently still a rather slow process.

There's a name for this: biorecycling. It also could potentially help turn the plastic waste into new products, which ultimately saves resources down the line. Biorecycling is an emerging and growing field, so it not an overnight solution, Yet, it does open up possibilities of cleaning up oil spills, eliminating microplastics from water sources, and helping tackle hard-to-recycle materials. Additionally, with it being a new-technology, there are a lot of unknowns. Last thing anyone wants is for a solution to create new problems. Especially environmentally. (We've all seen the damage invasive species can do. Take Kudzu, Spotted Lanternflies, and Asian Carp for example.)

But it's hopeful to see a shift in the idea of "waste" as an end product. Rather than a dead end, it shifts to a "circular economy" model, transforming an item into something new rather than ending it in waste and pollution. Kind of nice to have a clean up crew of nature's tiny microbes!

Animal Habitats Matching Game

Canva is my go-to place for making all things beautiful: presentations, class signs, image creation, graphic organizers, and more. I've written about it time and again.

With the influx of AI and the integration of AI tools in so many educational platforms over the last two years, Canva has done a great job of keeping pace. They've added to their "magic tools" in many ways, and it has been fun exploring them--especially the Canva Code--to see what potential they have. It's been a good way to learn along the way how to make tools that could be useful in the classroom. (See these posts for other interactives I've created this summer using Canva Coding: Independence Day & The Declaration of Interdependence and Plastic Eating Microbes to the Rescue one.)

This Animal Habitats Matching game is my latest adventure. Geared to the 4th or 5th grade level, this game was created using their "Canva Coding" tool. It started with the prompt: "Design an interactive matching game for 4th or 5th graders about animal habitats, with images of animals and their natural environments. Provide immediate feedback for correct and incorrect answers." Of course, it took a lot of tweaking, at least 6 versions, and hundreds of line of code for this game to pop out. I'm pleased with the outcome! The beauty of this drag-and-drop game is that it does all of the following:

• teaches animal habitats in a hands-on, interactive fashion;
• provides instant feedback for both correct and incorrect answers--while also keeping score of correct matches and attempts;
• provides hints when needed and positive reinforcement for learning;
• saves teachers time in creation of materials.
