Examine exactly what is meant by natural selection, as well as how it works in nature and through the assistance of humans. Presented with fun graphics and simple narration, the complex topic of natural selection is clearly explained in eight minutes. Part of a series of videos, it can stand alone or be used with the other videos to gain a deeper understanding of the covered concepts.
Students develop an understanding of natural selection, specifically, how it unfolds from generation to generation. They work in small groups to perform an experiment using beans. They use a worksheet imbedded in this plan to guide their research.
Charles Darwin and Jean Baptiste Lamarck are credited for developing the theory of natural selection. After teaching your beginning biologists about acquired characteristics, they read the included selection and answer questions that follow. Finally, they arrange pictures of elephants at different points in the life cycle and over more than one generation to model how changes in characteristics occur over time. Neatly drawn and formatted cards can be laminated for continuous use.
The pocket mouse can be light brown like the sands of the desert, or dark brown like the volcanic lava flows that are interspersed throughout New Mexico's Valley of Fire. It seems that predators have weeded out light colored mice in this volcanic landscape. Scientists examine the genetic mutation in the gene Mc1r that leads to dark colored fur and formulate an explanation. Not only will you find an award-winning video here, but also four related lesson plans and a hands-on activity for your biology class.
Students simulate natural selection using pinto beans. In this biology instructional activity, students identify the factors affecting organism evolution. They record data from the experiment and formulate a conclusion.
Introduce the topic of evolution and natural selection with visuals, vocabulary, and historical perspective. Budding biologists can examine the evidence on their own by going through the presentation, or the teacher can present to the whole class, stopping for discussion along the way. Learn about the observations Darwin made while in the Galapagos Islands, as well as what drove him to publish his work.
This editable learning exercise is set up so that biology pupils read four case studies and identify points that are present in each, such as overproduction, heritable variation, struggle to survive, and differential reproduction. They also predict how each population is likely to change over time. For each case, a cute cartoon animal adds interest. Although you might not cover all of the same terms in your specific curriculum, the case studies are useful. You can alter the analysis questions to more closely fit concepts of your choice.
It's Mr. Anderson, and he's ready to explain natural selection! Be excited, because he has the ability to make scientific biology and genetic functions in terms of natural selection make sense. With great examples and a clear and gentle manner, Mr. Anderson could be a big help in explaining complicated concepts.
Students examine how Darwin used the processes of science to support his theory. They distinguish between artificial and natural selection, recognize Darwin's contribution to science. They produce a newspaper describing the times in which Darwin introduced his theory of natural selection, reporting the public reaction to his theory.
Here is yet another variation of the classic activity in which lab groups use different tools to imitate different bird beaks as a demonstration of one of the factors in natural selection. What makes this one unique is that it is on a brightly colored worksheet and is followed by an assignment to write a paragraph about the occurrence of natural selection. Genetic variation and mutation are mentioned as part of the lesson.
Learners view video showing recent field work on a twenty two-year study of finch beaks on a small island in the Galapagos, showing natural selection clearly operating in the wild.
Eleventh graders explore natural selection using an interactive online website. In this biology lesson, 11th graders research about a specific natural selection topic. They create a visual aid about it and share their findings in class.
A sufficient slide show on natural selection is available to use with your biology class. It introduces viewers to foundations of this mechanism of evolutionary change. Notes are provided to support your lecture on genetic variation and the three types of selection: directional, stabilizing, and disruptive. Helpful graphs and photos enhance understanding of the concept of natural selection.
Students solve the following problem concerning the evolution of seed color in pinto bean plants: "How does natural selection change the frequency of genes or traits over many generations?" They use the constructivist approach to studying as they work in teams to design and conduct an experiment that solves this natural selection "problem."
Students discuss and role-play the elements of natural selection. They use toothpicks to represent Stick-Worms and discover the mechanisms of change of traits in populations.
Learners use discussion questions, handout information and research topics to explore several issues related to natural selection and evolution. They examine Darwin's research on the finch and antibiotic resistance.
Learners examine and identify examples of species that developed as a result of immigration, genetic drift, and adaptive radiation. They conduct Internet research and define key vocabulary terms, and use their species example on their Natural Selection Foldable.
Eighth graders list the steps of Darwin's natural selection. They demonstrate the process of natural selection in a predation activity. Students create paper origami frogs to race across the floor and analyze the differences in the shapes.
Students produce a newspaper describing the times during which Charles Darwin introduced the theory of natural selection. For this evolution lesson, students make observations and explore the role of observation in Charles Darwin's work. They use multimedia tools and newspapers to help them create a newspaper about Darwin's times and work.
Fourth graders represent a new predator on a population of colored worms. They mathematically determine the effect of the new predator on the survival and reproductive rates of the worms, simulating natural selection at work.
