The ones that we know are:
React
Respond
Grow
Give off waste
Take in nutrience
They are the only 5 that I am sure are right.

Hope this helps your nephew. The link below will expand on what I've listed here.
1. Vision/Sight
2. Smell
3. Sound/Hearing
4. Taste
5. Touch
6. The passing of time.
7. Temperature
8. Balance
There are energy forms that we do not seem to be able to sense.
Electric fields - Eels and sharks detect electrical fields to guide them to prey through special sensors in their skin.
Magnetic fields - Homing pigeons seem to use the Earth's magnetic field to find their way. (Scientists not sure where the sensor is located.)
(NOTE: Is it possible that humans might also be able to detect electric and magnetic fields, except that our ability is too weak to notice it?
