point.
- Watch Eco-Friendly Packing Peanuts-Cool Science Experiment video provided by Spangler Science TV.
Discuss how the packing peanuts made from corn are so much more earth-friendly.
- Why are the peanuts made from corn better for our earth? Answer – They decompose when the rain falls on them in a landfill.
- What are some items that are made of Styrofoam? Answer – packing peanuts, coolers, cups, meat trays, packing sheets that are used with large products like televisions, egg cartons, to-go boxes, flotation
devices, etc.
- Why is it better if trash items decompose? Answer – Because when items break down into little pieces that become part of the soil, there is less trash that stays in our landfills.
- Look at how these magic corn pellets are made. Watch Packaging Peanuts Biodegradable Compostable Packing (How It’s Made) Video.
- Discuss the video.
- If you have the biodegradable packing peanuts, use them to make sculptures and projects by dipping them in water and sticking them together.
Note: Corn is not only used to make packing peanuts. It can be used to make biodegradable plastic that decomposes just like the packing peanuts. This corn plastic can be made into silverware and cups that we use.
- Read Cool Corn handout from Kansas Agriculture in the Classroom.
Read the directions on the last page of the handout to make your own biodegradable corn plastic. When completed go over the following questions:
- What do you notice about your biodegradable plastic ball? Answer: The liquidly substance turns into a rubbery plastic that can be molded.
- What could you make with this biodegradable plastic if you let it harden? Answer: Any shape you want
- Why is this kind of plastic better for our environment? Answer: biodegradable
- Closing: Corn is used for many products that we use in our world, and many of these products help us save our earth. Watch Uses of Corn.
