Help need some creative ideas on teaching project for neonatal thermoregulation

If you're trying to put an emphasis on NTE, then one suggestion would be to bring a thick blanket and have 2 of your friends as your "demo" sit in front of the class. One of them will keep whatever they have on(jacket/coat/hat/gloves) plus the blanket over them, while the other one gets to take off as much of their outerwear that they can take off without getting censored( ask them to wear a tank top and shorts).
Then you can actively demonstrate to your class the effect of thermoregulation in neonates by having each of your demo tell you how a baby would be reacting to their current state of "dressed/undressed".
Hope this helps!
