Human Body



1.     Taste Test – Grab some foods with similar textures but different flavors like banana yogurt and strawberry yogurt, or different colored jelly beans. Get someone to help you and be the judge. Close your eyes and hold your nose closed while you taste the items… Can you tell the difference between the purple jelly beans and the green ones?  Can you tell one yogurt from another? Probably not!  That’s because smell is a huge part of what we call “taste”.

2.     Senses Experiment – Have a grown-up poke small holes in 4 or 5 containers with lids. Put one “smelly” object in each container (lemons, bananas, orange peel, pine needles, a cotton ball soaked in perfume, chocolate, coffee, dirt, vanilla, garlic, onion, mint, vinegar, rose petals, pencil shavings, or whatever you come up with). 

Write a number on the side of each container. Tape a label to the bottom of each container to say what’s inside. Blindfold a friend or sibling and have him or her smell each container. Write down the number of the container, what’s inside and whether they thought it smelled ‘Gross’ or ‘Good’. Are the answers what you would say too? Which are good smells? Which are gross?

What is smell? Why do you need it? And how does it affect the food you eat? You might be surprised to learn smell is the most primitive of your five senses… In fact, it’s the very FIRST SENSE you use after you’re born — and 1 out of every 50 genes in your body is dedicated to it!  Whoa!
