Believe in Ohio STEM videos The Believe in Ohio program invites high school and college students, their instructors and the community to take a virtual field trip into the innovation economy of the future that is being built in Ohio through a series of six, free, regionalized, online courses. What this course is about and why is it important? Our nation is being challenged on an unprecedented level to maintain its historic prosperity. In the face of this challenge, over the last decade, the State of Ohio and its regions have been building Ohio’s innovation economy of the future. Today, the State of Ohio offers great promise for students who want to build a prosperous future for themselves by developing an entrepreneurial mindset, working hard, and applying what they are learning to develop the new products and services and jobs of the future.
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". 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. More experiments to try:
PCR Primers are short pieces of DNA that are made in a laboratory. Since they're custom built, primers can have any sequence of nucleotides you'd like. In a PCR experiment, two primers are designed to match to the segment of DNA you want to copy. Through complementary base pairing, one primer attaches to the top strand at one end of your segment of interest, and the other primer attaches to the bottom strand at the other end. Primers are also necessary because DNA polymerase can't attach at just any old place and start copying away. DNA Polymerase is a naturally occurring complex of proteins whose function is to copy a cell's DNA before it divides in two. The DNA polymerase in our bodies breaks down at temperatures well below 95 °C (203 °F), the temperature necessary to separate two complementary strands of DNA in a test tube. Nucleotides are the building blocks that DNA molecules are made of.
How do schools of fish swim in harmony? - Nathan S. Jacobs Emergence is a relatively new scientific concept that is becoming an indispensable tool for understanding, explaining, and predicting a variety of complex systems - from biology to economics to robotics. Examples of emergence include:Schools of fish. As mentioned in the lesson, individual fish follow simple rules for swimming close to their neighbors. 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. 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. You may also hear about the term "model."
Every city needs healthy honey bees - Noah Wilson-Rich Colony collapse disorder (CCD) is a phenomenon in which worker bees from a beehive or European honey bee colony abruptly disappear.Urban beekeeping is the practice of beekeeping in an urban environment. It has become popular in cities such as New York and London, which saw a 220% increase in beekeepers between 1999 and 2012 and and the practice recently became legalized in many American cities, including New York.Pollination is the process by which pollen is transferred in the reproduction of plants, thereby enabling fertilization and sexual reproduction.Best Bees Company provides and manages honey bee hives for gardeners in rural, suburban, and urban habitats. Best Bees presents a unique opportunity to anyone interested in these important little creatures, either for their role as pollinators of over 130 crops, or because their population numbers are on the decline. Varroa destructor can only reproduce in a honey bee colony.
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.
Which came first: the chicken or the egg? The chicken or the egg causality dilemma is commonly stated as "which came first, the chicken or the egg?" To ancient philosophers, the question about the first chicken or egg also evoked the questions of how life and the universe in general began.In yet another absolutely amazing display of nature's prowess, the contents of the egg are wrapped in a perfect, seamless, incredibly strong shell as though by magic! Eggs are objects of art. It turns out the chicken has little to do with the formation of an egg's shell -- the egg actually grows the shell around itself! It does this using processes that are also seen in bones and seashells.Why do eggs become hard when you boil them?
