Today the boys and I hosted a couple of families from our home learners group for a fun science activity. I have been in search of some fun science activities for the boys, however, when I came across this idea, I knew it might be fun to do with our home learners group.
salt water (salty)
sugar water (sweet)
lemon juice (sour)
vanilla extract (bitter)
cup of water to drink
tongue picture (here a scanned copy of the tongue I drew)
Before everyone arrived I had the tongue printout, 4 different colored crayons, 4 q-tips, and the 4 solutions set out on the table for each kiddo. I cut up old egg cartons so that each kid could have their own set of the 4 solutions.
Pre Activity Discussion:
Before we started the activity, we talked about the purpose of our tongues and what on our tongue allows us to taste. We also talked about things that taste salty, sweet, sour, and bitter. At this point the kids were ready to get started.
Take one q-tip and dip it into one of the four solutions. Touch that q-tip over different parts of your tongue. Then color (or put an X) on the area of your tongue where the taste was strongest. Repeat this for all of the solutions.
Staring down the first solution.
It was really funny to watch the kids taste the different solutions. It was also interesting to see how each one of them reacted to the different tastes. The sugar water was the favorite, the vanilla extract was the least favorite. However, the salty and sour varied from child to child. Also, each childs tongue map was just a little bit different, however, for the most part they were fairly similar.

Have you every done a tongue map?
