Well same like how you can only truly taste and enjoy what you’re eating if you can both taste and smell it.

Maybe but if practiced individually then they might be trained into more focused skills

Definitely. A combination of the different senses stimulates learning further.

Especially when it is hands on learning, more than one sense is being engaged

Not too sure. Different kids might have different abilities to learn

Using all senses helps the brain make better connections :)

I am not sure. Haven't heard of this kind of thing before

Multi sensory experience always helps kid learn faster

I think its also how they learn to multi-task

Not sure what research is this
