We tried an experiment this morning, from Janice Vancleave's 201 Awesome, Magical, Bizarre, & Incredible Experiments, investigating the effect of smell on taste.
Vancleave's experiment called for eating apple while sniffing a cotton ball, soaked in vanilla. But, I couldn't find our cotton balls, and the vanilla in the container did not seem to produce a strong enough scent to change our perception of the apple's taste. So, we switched to some freshly picked mint leaves.
First, I had the children taste the apple normally. They all agreed it had a pleasant, apple flavor.
Finally, keeping the mint leaves, under their noses, they tasted the apple again. This time, it tasted like mint. Even though they knew it was apple, and knew what it should taste like, the powerful smell of the mint, changed what they were tasting. It wasn't exactly like chewing on a mint leaf, but the flavor was definitely there.
What really surprised me was the refreshing minty aftertaste, that lingered even after the apple, and leaves were gone.
It's great to be a homeschooler.
