Common Misunderstandings of Evolution: Part 1 While an open and honest debate is always a good thing, most of the time, when people are pointing out “problems” in evolution, their qualms arise from a misunderstanding of what evolution actually is and how the mechanisms of evolution actually function. Below are some of the most common misconceptions (or questions) in evolution and how science answers these concerns. Q1.) How does evolution explain the origins of life? A.) This question, and variations of it, is one of the most common things that people turn to when trying to refute evolution—It can’t reliably predict how life first originated. In truth, evolution doesn’t explain anything about how life originated. How life originated is something completely different, called abiogenesis. Q2.) A.) This is, perhaps, the most well-known, as it is easily observed and demonstrated. In short, the organism is more “fit” for survival; this idea of “fitness” is central to natural selection. Q3.) A.) Q4.) A.) Q5.) A.) Stop by and say hello.
The Biology Corner Scientific Studies: Scientific Method Learning about the scientific method is almost like saying that you are learning how to learn. The scientific method is a process used by scientists to study the world around them. It can also be used to test whether any statement is accurate. You can use the scientific method to study a leaf, a dog, an ocean, or the entire Universe. We all have questions about the world. Just about everything starts with a question. So you've got a scientist. As more questions are asked, scientists build a foundation of answers. The whole process allows the world to advance, evolve, and grow. Experimental evidence is used to confirm the answers in science. Scientists start with general observations and then make a hypothesis. Once you have a scientific hypothesis, the fun can begin. It is very important that the experiment is objective. So what about that first hypothesis? There are different terms used to describe scientific ideas based on the amount of confirmed experimental evidence.
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
Nature Publishing Group : science journals, jobs, and information 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.
stroop effect The famous "Stroop Effect" is named after J. Ridley Stroop who discovered this strange phenomenon in the 1930s. Here is your job: name the colors of the following words. Do NOT read the words...rather, say the color of the words. For example, if the word "BLUE" is printed in a red color, you should say "RED". Say the colors as fast as you can. Try this Interactive Stroop Effect Experiment. [Run Experiment] Also available: print out Stroop Test Mini Cards. Why? The words themselves have a strong influence over your ability to say the color. Speed of Processing Theory: the interference occurs because words are read faster than colors are named.Selective Attention Theory: the interference occurs because naming colors requires more attention than reading words. I think that this puzzle would be easier for a very young child than for older children or adults. My scores: Test #1 = 10.1 seconds; Test #2 = 22.4 seconds It took me more than TWICE the amount of time to read the "confusing" words.
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 yellow rectangles show the genes that the parents have. The genes of one parent are in the two boxes at the top: the A and the A. This parent has one copy of this gene on each of two chrosomes. The genes of the second parent are in the two boxes at the left side of the diagram: a and a. This parent also has a pair of chromosomes with one of these genes on each one of the pair. The green boxes represent what each of four children will inherit. Each child inherits one gene on the chromosome it gets from each parent. One gene plus one gene = 2 genes: in this case, Aa. You may want to use Punnett squares to explain how your life forms pass on characteristics, or to help you to figure out what is going on in the Chromosome Kindergarten! Let's try some samples and see how these squares can help us. The orange bird has two dominant Agenes.
