that use a chemical reaction to release energy in the
form of heat, and develop a decision matrix to help
you weigh the pros and cons of each. Determine the
type of chemical reaction that occurs in each heat
pack and the amount of energy released by each
reaction. Consider what situations or environments
each kind of heat pack is designed to work within. ]]> 2022-04-15 18:51:37 UTC https://padlet.com/rhyanna_johnson2/bsbartdpvonu6zid/wish/2145113509 rhyanna_johnson2 https://padlet.com/rhyanna_johnson2/bsbartdpvonu6zid/wish/2145114281 Making Heat Packs]]> 2022-04-15 18:53:10 UTC https://padlet.com/rhyanna_johnson2/bsbartdpvonu6zid/wish/2145114281 shaynebuddman1 https://padlet.com/rhyanna_johnson2/bsbartdpvonu6zid/wish/2147117575 Monday 5/23/2022]]> 2022-04-18 15:21:06 UTC https://padlet.com/rhyanna_johnson2/bsbartdpvonu6zid/wish/2147117575 shaynebuddman1 https://padlet.com/rhyanna_johnson2/bsbartdpvonu6zid/wish/2147118438 There are many different types of heat
packs available, but what are the
differences between them? Research
heat packs and the different ways they
release energy in the form of heat. Your
engineering challenge is to build a heat
pack and optimize it by increasing the
temperature or making it last longer.]]> 2022-04-18 15:21:46 UTC https://padlet.com/rhyanna_johnson2/bsbartdpvonu6zid/wish/2147118438 Research Poster (Slide) shaynebuddman1 https://padlet.com/rhyanna_johnson2/bsbartdpvonu6zid/wish/2147123943 REQUIRED:
