Your senses—sight, touch, taste, smell, and hearing—are part of your nervous system. They work together to help you make sense of the world around you by sending signals that your brain decodes. Grab a blindfold (no peeking!) to test them out.
Find a partner and ask him/her to hand you a mystery item. As you try and guess what it is, have your partner record your observations.
1) How does the object feel? Soft or hard? Heavy or light?
2) How does it smell? Sweet or sour? Earthy or flowery?
3) If it's food, how does it taste? Bitter, salty, or sweet?
4) Try tapping or shaking the object. Does it make any noise?
5) Try to guess what's in your hand.
Take off your blindfold and draw what you were actually holding. What sense most helped you identify this object?
Aligned with Next Generation Science Standards (NGSS):
K-LS1-1. Use observations to describe patterns of what plants and animals (including humans) need to survive.
1-LS1-1. Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs.
4-LS1-1. Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.4-LS1-2. Use a model to describe that animals receive different types of information through their senses, process the information in their brain, and respond to the information in different ways.
MS-LS1-3. Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.
MS-LS1-8. Gather and synthesize information that sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or storage as memories.
HS-LS1-2. Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
HS-LS1-3. Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.
