Science Experiment for Sense of Touch
In this experiment, we will explore the sense of touch. Your sense of touch is one of the most complicated senses. How come? Because there are many types of touch. For example, place your hand on any flat surface around you. Did you do it? How do you know? Because your brain tells you that your hand has made contact with the surface through the sense of touch.
But, your sense of touch can tell you so much more than just if you made contact. For example, is the surface you are touching rough or smooth? Is it hot or cold? Is it dry or wet? Is it still or vibrating? Your body is able to sense pressure, vibration, temperature, and pain. You probably didn’t realize how much information is passed to your brain through the sense of touch!
Touch is a powerful sense after all, and it can release a series of emotions and memories that aid in learning. Since roughly 30 to 40 percent of people are considered tactile learners, the ability to touch while learning could be vital to their success. From building models to exploring ropes and knots, hands-on learning provides context and allows your child to reflect and engage.
How does the Sense of Touch Work?
The skin is the largest sensory organ of the body. The skin is sensitive to many different kinds of “stimuli”, such as touch, pressure, and temperature. Within the skin, there are different types of “receptors” that are activated by different stimuli. When a receptor is activated, it triggers a series of nerve impulses. For a person to “feel” the stimulus, the nerve impulses must make their way up to the brain.
The Sense of Touch is spread throughout the whole body. Nerve endings in the skin and in the other parts of the body send information to the brain. There are four kinds of touch sensations that can be identified: cold, heat, contact and pain. Our skin is the largest organ in our body and contains the most nerve endings. The fingertips have a greater concentration of nerve endings.
Let us study how children can figure out the object with only touching.
What all you need:
1. A few pair of socks
2. Different texture materials. (cotton, paperclip, candy wrapper, pup toy, car, Lego bricks, ball, kidney beans) possibilities are immense.
3. Click and download the Printable.
1. Put each object in one sock each.
3. He/She can touch the object and then tick on the expressing the feel being rough, smooth, bumpy, soft, hard. It doesn’t have to be correct.
4. To make it hard don’t give them the Printable and ask them to guess the object by using the Sense of Touch only.
Kids can also come up with answers looking at the shape of the sock, Sense of sight. Combining all the five senses can be extraordinary learning for children.
Research has confirmed that early touch experience is extraordinarily important for the development of both cognitive function and a healthy body.
This is why, nowadays, when premature infants are born and put in isolators, they’re taken out for a few hours a day, and pressed against a parent’s skin. Initially, when isolators were first invented, people thought you should just leave them in there alone, so they don’t get infected. But then they might not get touched for the first two months of life, which turns out to be disastrous.
