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.

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.
World Builders: Punnet Squares E Viau CSULA Punnett Squares Punnett Squares are diagrams used by scientists to help them to figure out how inherited traits (characteristics) will be distributed. 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.
Using the Internet to Do Punnett Squares Summary:Using a computer connected to the Internet, the student will construct and use Punnett squares of monohybrid crosses to explain how genetic traits are passed to offspring. Main Curriculum Tie: Science - 7th GradeStandard 4Students will understand that offspring inherit traits that make them more or less suitable to survive in the environment. Materials: computer lab (1 computer per 1-3 students) or TV or Video projector connected to a demonstration computer paper and pencil Background For Teachers:This lesson is best done after students have been introduced to the concept of the Punnett square and how it is used to predict possible traits of offspring. A Punnett square looks like a box divided into four squares. Intended Learning Outcomes:1. Instructional Procedures:1. 2. 3. Before you click the "Breed" button, write down a Punnett square showing your predictions of what the offspring will look like for the chosen trait. 4. Extensions:Visit the Mutant Fruit Fly exhibit.

Five fingers of evolution - Paul Andersen In his talk, Paul Andersen explains the five causes of microevolution. Research one example for each cause in the human population. Use the following population simulator to simulate microevolution: Run the simulation using the default settings. Note the change in gene frequencies due to chance.
