To the child who said it was apple juice, I asked them to smell it. Did they still think it was apple juice? I then asked if they wanted to taste it to make sure. If they were absolutely positive it was apple juice, why not taste it? If you were wondering, the student declined as did everyone else. Would a scientist taste or touch something if they thought they knew what it was? "Ms. Sarah, what if it was poison? It looks like apple juice and could smell like apple juice, but it could be a dangerous chemical!" I agree! I then assured the group that I would never bring in a dangerous chemical. After all, we were to use our senses to describe what we could about what was in the jar.
Off we went. Taking turns in small groups, we used four out of five senses to come to a better understanding of what was in the jar. We recorded our observations and came up with a variety of descriptive language:
- yellow
- smooth
- silky
- gross
- clear
- nothing (sounds and smells like)
- eggs
- yummy
- slippery
- doughy
- nothing
Have you figured out what it is yet? It's vegetable oil!
The mystery substance we used next was obviously different. It was blue. Using the same strategies, sea tried to learn more about it. Here are some of the things we came up with:- blue
- wet
- yucky
- cold
- no sound
- water
- cleaner
- sour
Do you know what this one is yet? It's vinegar! I added blue to make it a little bit tricky.
After discussions on both liquids, we spent time comparing them so we could really notice the differences. This will come in handy when we come up with ideas for experimentation. I have a feeling the next two substances will have more in common. Look forward to that post!
