I'm Sensible

"All our knowledge begins with the senses, proceeds than to the understanding, and ends with reason. There is nothing higher than reason." Immanuel Kant

This week we are studying the nervous system. The nervous system is a network of cells that coordinate the body's actions and carry signals from one part of the body to another. Before any of this can happen though, information has to come into the body. Your five senses gather the information for your nervous system. Our lab this week focused on testing how well the children's senses worked. It was a great excuse to blindfold the children and subject them to hideous smells! We used vinegar and garlic to test their sense of smell...this was funny! Sight was tested with an orange and white vinegar placed in a clear jar. Next we used chocolate chips and apples to test their sense of taste. Bells and coins provide the sounds to test their hearing. Finally we used a Q-tip and a pencil for their sense of touch. The kids had to guess what everything was using only the sense specified. Fun was had by all and there was much giggling and gagging. T wanted to test his senses further and let me lead him around the backyard blindfolded.....obviously he still trusts me.....not sure how long that will last! Next week is genetics...I foresee a birds and bees conversation ensuing...wish me luck;)
