Since we are continuing our learning journey about body systems, after learning about the digestive system and some of its components, we are now looking at our sensory systems.

This week we explored how our skin has many neurons: touch neurons, pressure neurons, temperature neurons and last but not least, pain neurons.

We carried out a little experiment to “fool our senses” by putting one hand in ice cold water, and the other hand in warm water, and then after 10-20 seconds we put both hands at the same time into some room temperature water.  We found that the hand that had been submerged in ice water experienced a much warmer temperature in the room temperature water, than the hand that went from warm water to the room temperature water.  Some of the boys and girls in the class concluded that our senses aren’t always that reliable, and things in our environment can change that.
