This project will be like a guessing game. We have groups of six little medicine bottles, with liquids inside and the lids on tightly. There are only three different liquids.

Without opening the bottles, decide which ones match, and put them next to each other. What made you decide that your sets of liquids matched? They are all the same color, aren't they?

Can you name the liquids that are in each bottle?

Next, you may open the bottles--be careful, because we don't need to be spending the rest of the day cleaning messes!

Smell the liquid in each bottle and match the sets again--did you match them the same this time as you did the first time?

Can you name the liquids that are in each bottle?

Put your fingertip into each one and feel the liquids, by rubbing your thumb onto the fingertip. Do all the liquids feel the same? Do your sets still match, or you have to
change some of them?

Can you name the liquids now?

Are they water, sugar water, and white vinegar? How can you tell?

This doesn't seem very scientific, does it? In addition to all the fancy equipment they have, scientists must also use their own senses when they want to learn about something.

Can you name the five senses?

Which sense do we have that we must not use for science projects?

STUDENTS MUST NOT TASTE THINGS WITHOUT PERMISSION. TASTING CAN BE VERY DANGEROUS.
