Seventh graders model radioactive decay using pennies, collect data from their model, apply scientific visualization techniques to their data and create animated models explaining the concept of radioactive half-life.
A well-written lesson plan, second in a series of four, gets high schoolers exploring how the Antarctic food web is impacted by climate change and the associated melting of polar ice sheets. It begins with a PowerPoint presentation about the polar ecosystem. Small groups use beads and game cards to model how decreasing sea ice impacts the food web. To close, a class discussion ensues about ocean acidification and what pupils learned from the activity. Be sure to consider using the entire unit in your environmental studies course.
As the great and hilarious Tim Minchin once said, "Science is simply the word we use to describe a method of organizing our curiosity." Science is more than just a guess; it is based on questions, observations, and evidence. High schoolers begin the lesson by developing their own questions about evolution, then visit a large assortment of websites to see what evidence is out there to support any answers to the questions. Some may find that there aren't answers to their questions; this is all part of science.
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.
High school biologists try to determine if the red wolf is a purebred species or a hybrid of coyote and gray wolf by examining the DNA fingerprints of all three. Twenty-one pages of material are provided here, including student worksheets and a plethora of extension ideas. This is a well-written and comprehensive lesson plan that explores natural selection, conflicting scientific data, and the investigative process.
Students explain the concept of gene sequence analysis. In this gene lesson plan, students draw inferences about phylogenetic similarities of different organisms.
Students examine how natural selection creates antibiotic-resistant bacteria, recognize applications of evolutionary principles for medicine, agriculture, and conservation, and discuss how science contributes to decisions in context of society.
Students demonstrate how organisms adapt to their environment. They examine prey and predators, natural selection, and adaptations by representing oyster morph.
Learners investigate how natural selection influences evolution. They complete a hands-on lab simulation of natural selection, and replicate a real experiment and examine the interplay between selection factors in a population of guppies.
Using origami paper birds, your biology class will experiment with mutations and natural selection to determine wing position, length, and width. It would be helpful to provide a worksheet to go with the activity that includes a procedure for creating the birds and for the natural selection exercise. Use this memorable simulation to enhance your evolution curriculum.
A colorful wedge of Earth, map of tectonic plates, and numbered facts about Earth structure fill the first two pages of this resource. After reading and absorbing the information, geologists get into groups and make clay models to demonstrate faulting and folding of Earth's crust. A second activity is also included in which individuals research Pangaea, Laurasia, and Gondwana. Plenty of background information and a grading rubric are included to support you with these assignments.
Students investigate the relationship between humans and yeast. In this evolution lesson plan, students compare amino acids in a variety of life forms. Students will watch films on similarities of the genetic code that structures an organism.
High schoolers examine mechanisms behind biological evolution and the theories that feed it, and are able to demonstrate their knowledge of these theories in a story.
This nine-page biotechnology resource contains six pages of questions regarding DNA technology. Questions cover cloning, restriction enzymes, the polymerase chain reaction, different techniques, the human genome project, and more. The last three pages of this resource is an outline of what we have learned and what is yet to uncover about the human genome sequence. Since information was gathered in 2005, this portion may need updating. Otherwise, the questions are pertinent to your advanced biology course.
The concept approached in this PowerPoint is the overall frequency of genetic factors in a population. The Hardy Weinberg Theorum is explained. Examples are given using alleles and genotypes of wildflower color to illustrate the numbers. Other examples are used to explain genetic drift and geographical variation and selection.
Thirty short-answer questions comprise this detailed review of evolution theory. Many of the questions ask scholars to define vocabulary. Because short answers are required, this worksheet will take some time to complete. You could give it to your biology class to use as a review of concepts before a quiz.
Students trace the history of evolution. For this biology lesson, students review evidence that supports the evolution theory. They give examples of different agents of evolutionary change.
Students identify the different types of fractals. In this geometry lesson, students use math to analyze different biological phenomena. They collect data from the experiments and construct graphs.
In this biology word search activity, students search for 29 words that are located in a word bank at the bottom of the page. They find words such as chromosomes, alleles, DNA, and populations.
Students read an article by Niles Eldridge about species and the environment and break into small groups to discuss it. They write essays noting strengths and weaknesses of punctuated equilibrium and gradualism, or other topics listed.
