Vocabulary Intended- Planned --- I meant to do that Unintended- Not on purpose --- Just Happened - Did I do that? Benefits- Positive or Advantage --- Made people's life easier Consequences- Can be Positive or Negative --- Results or Effect--- Sometimes referred to as “costs” Benefits= Positive Consequences

Example #1 John left science class. He stopped at his locker to get his math book. Then he went to the restroom. However there were several other boys waiting in line. It took a few minutes before it was his turn. When he left the bathroom, he felt rushed to get to class before the bell. He decided to run to class. What was the intended benefit of running to class? What could be an unintended consequence of running to class? Is there always a benefit? Is there always a consequence?

Check for Understanding Define the following terms: Benefits- Consequences- Intended- Unintended-

Answers Benefits- Positive impact or outcome, Advantage Consequences- Positive or Negative result or outcome Intended- What was meant or planned Unintended- Not planned, just happened

Thoughts to Ponder “How many uses can you think of for a brick?” This question is often asked by recruiters trying to gauge a person’s creativity. Most people come up with common uses such as: • Build a building • Door stop • Paper weight But some truly creative types go farther. They think of uses that relate to their particular culture, or circumstance. Uses that are not remotely related to the original use, intended by the brick’s creator. • Murder weapon • Fish tank ornamentation • Primitive measuring device Researchers have shown that technology is frequently adapted to local circumstances. Tools created in one place for one reason bring unintended consequences and unintended use some where else.

Intended vs. Unintended Prezi- https://prezi.com/igc0mkhdt4qo/intended-benefits-and- unintended-consequences-of-technology/

Intended Benefit -- Can be only Positive Car ---- It saves time, comfortable to travel in Fast Food --- Convenience

Unintended Consequences – Positive or Negative Car ----- Pollution, Loss of Land, Fatal Accidents Fast Food --- Weight Gain, Unhealthy habits, Creates Jobs

Real World Example 2013 https://www.youtube.com/watch?v=2JNSpMhJLvg As you watch the above video about Cube Watermelons look for the intended benefit and the unintended consequences of changing the shape of watermelons.

What about cell phones? Intended Benefit? Unintended Consequences?

Text Messaging A comical example is text messaging. Engineers originally imbued phones with the ability to send texts only so they could test whether the phone in fact worked. They never thought in a million years that users would choose to send short messages to each other when they could call instead. But, it turns out, mobile services are priced in a way that encourages consumers to text. For many, sending a quick “where r u” is much cheaper and easier than placing a call. Moreover, as we eventually discovered, certain situations arise where text messaging is the far superior method of communication. Text messaging has evolved from a geeky diagnostic tool to a multi-billion dollar business.

Benefits of Electronics Consider electronic gadgets – cell phones, digital cameras and video cameras, MP3 players, flat-screen TVs, laptops, and so forth. Brainstorm the benefits of these devices with your partner. Create a list on your notepage.

Possible Answers Benefits of Electronic Devices: Easier communication Access to data/info Entertainment Mobility

Electronics Negative Consequences Now brainstorm “costs” or negative consequences. Work with partner to create a second list on your paper.

Possible Answers Electronic Negative Consequences: How much they cost- Expensive Certain games only for certain devices Apps, subscription services, etc. cost more money What about the energy cost? What about the polar bears?

How is your electronic device use killing polar bears? Wireless devices require electricity to recharge Energy cost means burning fossil fuels Burning fossil fuels means more carbon dioxide released into atmosphere More CO2 means increased greenhouse effect Increased greenhouse effect means more global warming More global warming means less glacial ice Less glacial ice means less habitat for polar bears Less habitat means fewer polar bears Fewer polar bears could lead to extinction

Reflection Rather than being discouraged, here’s a challenge. Remember the many benefits of technology and acknowledge that electronic gadget use will continue to grow rapidly. How can science and technology address the unintended environmental consequences of these tools?
