Compare and contrast the theories of two famous evolutionary biologists: Jean-Baptiste Lamarck and Charles Darwin. Beginning biologists answer 11 questions after reading about the theories. Critical thinking as well as reading comprehension are both required. This makes a handy homework assignment to give during your natural selection unit.
This is mostly a reading comprehension exercise with a focus on rock and fossil formation. After a section on the three types of rock, readers answer two questions about which environment is conducive to fossilization. After a second section, they answer questions about the steps in the fossilization process. The end of the student sheet addresses fossils from the Langebaan area, but you could leave this out. Teacher's notes are provided to help you lead a class discussion.
After reading about the five main theories explaining the mass extinction of dinosaurs, natural historians diagram a geological timeline, describe how the five factors might have caused mass extinction, and then create a poster of an animal that has recently become extinct. A reading passage and student instructions sheet are included, as well as teacher's notes and a rubric for grading the poster. Although the lesson plan states that it is intended for 10th grade, it really can be used from fifth grade on up.
Young scholars use the methodology described by Prown (1982) to interpret paintings. They determine artistic, historical, and scientific content and develop an understanding of aspects of nineteenth century American culture. They study the paintings for their internal content and evidence.
Students take a closer look at the Parthenon. In this world monument instructional activity, students watch PBS video segments about the reconstruction of the Parthenon in Greece. Students research how the ancient Greeks built the structure and discuss how reconstruction teams refinished it.
Seventh graders explore the connection between genetics and heredity by examining the cellular structure. Among the numerous activities to engage students are drawing DNA molecules, vocabulary puzzle sheets, and predicting possible offspring combinations by discovering the Punnett Squares to predict ratios for inherited traits.
High schoolers examine the guidelines the United States Department of Agriculture places on food. In groups, they create a list of the foods they consume and discuss the political and environmental implications of purchasing the food. They use the internet to research the food situation around the world and how food is stored and transported. To end the lesson, they discover how to be better food consumers to help protect areas of the world facing malnutrition and political unrest.
Reading and understanding informational text is a key element to understanding every discipline. Elementary learners read three different articles focused on various animals and habitats in the Hudson River. They answer comprehension questions about each article. Worksheets, articles, vocabulary, and answer keys are included.
Students are able to design, construct, evaluate and recommend materials for planned Eco-house to be built on campus. They investigate about good design and plan for construction. Students have a greater knowledge and appreciation of living with the capacities of the climatic and eco-systems of southern Minnesota.
Students are introduced to genetics along with genetic diseases and heredity. In groups, they complete a Punnett Square to determine the dominant and recessive genes. After viewing diagrams, they identify the characteristics of DNA and demonstrate the processes of Meiosis and Mitosis. To end the lesson, they discover the factors that cause genes to mutate.
