The Big Bang Disperses Energy (Camden) kliciale000 https://padlet.com/neumasop000/syd2d59tdg8c/wish/258064129 From threshold 1, all of the energy in the Universe was created with the Big Bang, an explosion of energy and complex elements.

The Sun Creates Energy (Sophia kliciale000 https://padlet.com/neumasop000/syd2d59tdg8c/wish/258065964 Relating to threshold 2, the stars light up, the Sun played a major role in the evolution of life from single-celled organisms to highly complex beings, like people and animals.

Humans Use Hands & Bodies for Energy (Braedyn) kliciale000 https://padlet.com/neumasop000/syd2d59tdg8c/wish/258067313 In relation to Threshold 6, Humans get help with walking finding and preparing food, go through physical obstacles and kill predators by using their hands and body (like Hunter-Gatherers).

Humans Use Tools To Harness Energy (Braedyn) neumasop000 https://padlet.com/neumasop000/syd2d59tdg8c/wish/258119059 Due to the creation of tools, collective learning and innovation continued with humans, this is related to threshold 6, collective learning.]]> 2018-05-04 17:54:48 UTC https://padlet.com/neumasop000/syd2d59tdg8c/wish/258119059 7. Humans Use Fire for Energy (Sophia) neumasop000 https://padlet.com/neumasop000/syd2d59tdg8c/wish/258119566 In relation to threshold 3, Fire could clear land in minutes,  cook food to change their taste, burn skin, light darkness, and turn light to heat

Humans Domesticate Animals For Energy (Lexi) neumasop000 https://padlet.com/neumasop000/syd2d59tdg8c/wish/258119762 Thanks to threshold 6,  humans domesticated animals that would present a source of energy to help with everyday tasks.]]> 2018-05-04 17:56:46 UTC https://padlet.com/neumasop000/syd2d59tdg8c/wish/258119762 5. Humans Use Coal & Steam for Energy (Sophia) neumasop000 https://padlet.com/neumasop000/syd2d59tdg8c/wish/258119961 Due to threshold 6 and 8 , there were several steam-powered devices 
-Positive effect: coal grew and extraction of this fossil fuel remained
energy intensive — and does so to this day.
-Negative effect would be coal polluting the air, mining was very time consuming although found a device that slightly helped. Steam isn't necessarily reliable,

Humans Use Natural Gas & Petroleum (Oil) For Energy (Lexi) neumasop000 https://padlet.com/neumasop000/syd2d59tdg8c/wish/258120049 Involving threshold 8, thousands of years of collective learning have enabled us to get new forms of energy and have encouraged an appetite for resources that can fuel further innovations.
Positive effect: We can use this to generate energy for many devices and fairly easy to transport.
Negative effect : We could run out eventually, expensive resource and burning oil creates carbon monoxide.]]> 2018-05-04 17:57:26 UTC https://padlet.com/neumasop000/syd2d59tdg8c/wish/258120049 10. Humans Use Nuclear Power For Energy (Braedyn) neumasop000 https://padlet.com/neumasop000/syd2d59tdg8c/wish/258120121 Similar to threshold 8, nuclear energy is another high in value product but contains high-risk details. 
- Positive effect: Relatively cheap, controllable, and easily produced. Can pollute the air but relatively small impact.
-Negative effect: nuclear power production creates highly hazardous waste that must be handled under very strict precautions.A breakdown or leak at a nuclear power plant, which threatens surrounding lands, wildlife, and human populations.
