100 Coolest Science Experiments on YouTube - X-Ray Technician Schools Although YouTube has something of a reputation as a repository for the inane mental diarrhea of stunted man-children injuring each other for cheap laughs or shrill teenage drama queens shrieking like harpies over the latest bland, interchangeable lump passing as the epitome of masculine beauty, many others thankfully take advantage of its services as a portal to share their knowledge and educate viewers. While few of the scientific offerings formally follow the scientific method or test an explicitly stated hypothesis, even those videos veering more towards demonstrating various principles, theories, and laws still offer visitors a chance to learn something about how the world around them operates. By this point, it should go without saying that many of the following videos contain procedures that may be dangerous to perform at home or without the proper equipment and/or training. Please do not duplicate any of these experiments unless assured that they are entirely safe for amateurs.
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. 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 A complete LESSON PLAN with teacher and student guides is now available. What areas of our bodies are most sensitive to touch?

The Biology Corner Synthetic Biology Synthetic biology is perhaps the most accelerating science. In fact, since biology became an information technology, for the past several years synthetic biology has been developing even faster than Moore's Law. And just one example - paralel to the pioneering days of computer science, is the explosion in DIY biology garage-based hacker labs. There is a large and rapidly growing number of relevant YouTube videos. This page will post a collection of some of the most interesting ones I could find but feel free to contribute more clips of your own: Synthetic Biology Explained From selective breeding to genetic modification, our understanding of biology is now merging with the principles of engineering to bring us synthetic biology.

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.

Over the past few years, the Flipped Learning method has created quite a stir. Some argue that this teaching method will completely transform education, while others say it is simply an opportunity for boring lectures to be viewed in new locations. While the debate goes on, the concept of Flipped Learning is not entirely new. Dr. It’s our opinion that one of the reasons this debate exists is because there is no true definition of what Flipped Learning is. Dr.
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?
