here are some fun ideas:
mostly age appropriate for about 3yrs and older:
1. blind fold grab bag: put blindfold on and put hand in
bag and describe what you feel and guess what it is.
can also be used for different grits of sandpaper
glued onto different blocks or even different grits on
one 20inch by 20inch by 1/2 inch flat piece of wood. can also do
same exercise with different weights of blocks, put
them in order of lightest to heaviest or what not.
2. can also blindfold and taste different fruits and
guess what they are.
3. making natural beeswax candles with different
essential oils is great for sense of smell.
