AbstractAbstract

The promotion of STEM education is enthusiastically embraced by science and math teachers, but the T & E of STEM are less often evident, and typically perplex teachers on how to effectively incorporate into lessons. This presentation will use the Crosscutting Concepts of NGSS to show how to effectively intertwine engineering and science practices into the classroom to promote student learning and success in STEM

Your turnYour turn

• What engineering applications fits the standard that you selected above?

Some ideasSome ideas

• Create a machine for a children’s museum that would simulate a cell.

• Design an experiment that will prove that only the weight of an object will affect its frictional force. Hint: keep the surfaces made of the same material, and use an incline plane.

31

Some more ideasSome more ideas

• Create a game that will simulate the energy dynamics of molecules breaking apart and coming together. Do a storyboard to show the stages you expect to simulate

32

Even more ideas 

• Zeus & Hera are wanting to create life on earth, so they assign the lesser gods to engineering teams to create a unit of life. They are to use a space large enough for them to walk through it to do their work. When they are done and have argued their cases to the ruling gods, then they will shrink it down to a miniscule size—they are not sure what to call it, a house, a room, a cubicle, maybe a cell. The teams are to decide what the various processes should be inside the dwelling, to guarantee life.
