touch experiments Touch Experiments Some of these experiments require a blindfold. Keep in mind that some people do not like to be blindfolded...you could ask them to keep their eyes closed, but don't count on them having their eyes closed for a very long time. 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. Fine Fingers Grades K-6 We have the ability to tell whether objects are cold, hot, smooth or rough. smooth (an apple) rough (sand paper; rock) cold (ice) warm (a sun-warmed piece of metal) Tell someone to close their eyes (or use a blindfold) and touch the items to the person's hands or fingers. Sand Paper Rankings Grades K-12 To demonstrate the exquisite sensitivity of our sense of touch, try this one. Questions and Comparisons: Check to see if you (or your test subject) did it right. Materials: Sandpaper - various grades Wood Blocks (optional) 2-Point Discrimination Grades 3-12 Map Your Homunculus Materials
Test your sense of touch Is the Glass of Water Hot or Cold? With this experiment, test your skin's ability to perceive whether an object is hot or cold. What You Need: Three tall glasses of water, one filled with very warm or hot water (not burning), one filled with room-temperature water, and one filled with ice waterA clock to time yourself What You Do: Grab the glass of hot water with one hand, making sure that your palm is touching the glass. What Happened: Your brain just received confusing messages from your hands about what the temperature of the third glass was. You received these confusing messages because our skin does not perceive the exact temperature of an object. Two-Point Discrimination Is your skin equally sensitive all over your body? Ruler that measures in millimetersTwo toothpicksPartnerBlindfold (optional) Prepare for this activity by setting up a chart like the one listed below.
The Human Body This astonishing series takes us on a journey breathtaking twists of the most complex biological mechanism on earth - the human body. Using a technique that allows us to see photos changes over time, graphics, drawing and illustration calculated computerized techniques in order to investigate any effect, due to a corner of the human body in his various stages of growth, maturity and the final state - decay. Matriculation, girls, pains of adolescence, complex activity of the brain and eventually death shown in steps with detailed explanation. Offering clear voice of Dr. Robert Winston allows 10-year-old child even gain knowledge and understand the human body than ever before. Life Story – Every second, a world of miraculous microscopic events take place within the body. An Everyday Miracle – The drama of conception activates the most sophisticated life support machine on earth. First Steps – In four years, the new-born child learns every survival skill.
The Biology Corner Would You Eat That? The Game of Naming What's in What You Eat Getting the most out of what you eat takes knowing what's in your food. While packaged and prepared food can save time, it takes a lot of chemistry to keep those items edible on the long trip from the factory to your face. Play "Would You Eat That?" It's the game that makes you look at Your Appetite in a whole new light. Play the Game »
How to Extract DNA from Anything Living - StumbleUpon First, you need to find something that contains DNA. Since DNA is the blueprint for life, everything living contains DNA. For this experiment, we like to use green split peas. But there are lots of other DNA sources too, such as: Spinach Chicken liver Strawberries Broccoli Certain sources of DNA should not be used, such as: Your family pet, Fido the dog Your little sister's big toe Bugs you caught in the yard Step 1: Blender Insanity! Put in a blender: 1/2 cup of split peas (100ml) 1/8 teaspoon table salt (less than 1ml) 1 cup cold water (200ml) Blend on high for 15 seconds. The blender separates the pea cells from each other, so you now have a really thin pea-cell soup. Step 2: Soapy Peas Pour your thin pea-cell soup through a strainer into another container (like a measuring cup). Add 2 tablespoons liquid detergent (about 30ml) and swirl to mix. Let the mixture sit for 5-10 minutes. Pour the mixture into test tubes or other small glass containers, each about 1/3 full. Why am I adding detergent?
