The machine produced in various sizes, for both industrial and home uses, can easily transform a kilogram of plastic waste into a liter of oil, using about 1 kW·h of electricity but without emitting CO2 in the process. The machine uses a temperature controlling electric heater instead of flames, processing anything from polyethylene or polystyrene to polypropylene (numbers 2-4). Comment: 1 kg of plastic produces one liter of oil, which costs $1.50. This process uses only about 1 kW·h of electricity, which costs less than 20 cents!

Over the past three years, I have had the pleasure of volunteering and working at the Hands-on Biodiversity (HOB) Gallery at the Royal Ontario Museum. One of my many responsibilities is to use specimens and live animals to teach students about biodiversity, ecology, evolution, and anatomy. As a result of my experiences at the HOB gallery, I have become a strong advocate of hands-on inquiry learning and the importance of students experiencing science. By using specimens in this informal setting, students are able to learn about specific biological concepts in a unique and memorable way. One day, I aspire to incorporate hands-on learning with specimens and live animals in my own classroom, and hopefully, my fellow biology teachers will do the same.
