I play a game with my kids that they really enjoy. It has endless possibilities for keeping it interesting.
Sense of Touch: In the dark at bed time, I collect a few items, toys, tools, materials, ect and one by one hand the item to my child. I ask them to describe what they feel. They can't taste, or see, smell, or hear it. When they're really little, I can coach them with comments like "is it soft or hard, light or heavy, warm or cold, smooth or scratchy". My older child now is good at describing qualities. This is a great skill all by itself, but then I ask "what color is it." They usually have an answer, which prompts the discussion of what is truly knowable.
- Can you really tell from the sense of touch what color it is? We have a set of plastic critters, a brown bear and a panda bear are included in the mix, both from the same toy mold but painted differently.
- We talk about the 6th sense of mental formations, imagination. It is the picture in their mind that's helping them determine the color.
- Is it plausible that the color of the bear is not what you believe it to be?
- What other senses might you need to find out the answer?
Feeling the shape of a CD, is the music on the CD knowable without using their sense of sight or hearing?
Other senses: find items around the house that have a scent to them. If you have instruments, use them to make noise. Forage for some tasty items in the fridge, and turn the lights out. Point out that eating is both taste and the sense of touch (texture).
The older they get, you can use life examples:
1. The boy was mean to you and doesn't want to be your friend. How do you know that he doesn't want to be your friend? Facial expressions, body language, he said so. Is it plausible that the boy was angry, but that the friendship is not in danger? What can you do to find out?
2. (For big kids:) Your spouse doesn't like what you cooked, and thinks you are a mediocre chef. How do you know this to be true? Is it plausible that your mental formation is incorrect? What can you do to find out the answer? And how might you feel or behave differently if you were to find out?
