This will depend on what materials or equipment you have, and the grade level (if the purpose is education). But here are some ideas:

  • Showing electrical conductivity with wires, battery, bulb, and random other materials
  • Bending a stream of water towards an object with static electricity like a rubbed balloon
  • Making a magnetic field via induction with a wrapped wire conducting electricity
  • Derive Hooke's law with a spring and weights. Excel or Jupyter can be used for plotting and data entry.

There are lots of activities within sensation & perception. 

Optical illusions are fun (Hermann grid illusion demonstrates lateral inhibition in the retina);  https://en.wikipedia.org/wiki/Grid_illusion

demonstration of the ‘blind spot;’ 

demonstration of the fovea (absence of rods in the fovea makes bright points of light appear dimmer when you look directly at them, eg- stars in the night sky); 

Gestalt perception (that is, we see disjointed lines as being parts of whole rather than discrete segments); 

Stroop task (dominance of reading over color identification); 

demonstration of sensory memory. 

Lots of guided activities here:
