Sal share the timeline and process by which life propagated and colonized land. He covers life events that occurred during the Cenozoic, Mesozoic, and Paleozoic eras. The video is very basic and covers general knowledge of these eras and topics.
Introduce ecology classes to biodiversity and interdependence in ecosystems with a PowerPoint presentation. Then, they get up-close and personal with the invertebrate world by collecting insects, classifying them, and graphing their data. Links to the slide show, instructions for insect sampling, and dichotomous keys for identification are all provided for your convenience. Expect to invest up to five class periods for this mini-unit.
Students collect species data from a mock intertidal community. In this biology lesson, students graph their data and analyze the species in it. They construct a species accumulation curve and present it to class.
Students analyze marine sites to include in a biodiversity protection reserve and choose sites that provide the most efficient reserve system. In this protecting marine areas lesson plan, students study the species richness and diversity index of species in 8 different sites and determine which combination of sites are the most efficient to make a successful biodiversity protection reserve.
You will get much mileage out of this resource. It is three presentations in one! Standard general ecology information is included within these 69 slides. The first segment deals with levels of organization, biotic and abiotic factors, biomes, biodiversity, and the flow of energy. The second section focuses on nutrient cycles. The final installation examines population dynamics with an emphasis on problems accompanying overpopulation. The font may be considered "cute." This is easily altered if this is not to your liking. Otherwise, this is a terrific resource!
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.
Students study biodiversity while examining insects. They research insects that already exist and how they adapt to their environment.
Students explain what biodiversity is and how adaptive features are maintained in a population.  In this biodiversity lesson students complete a simple activity involving mouse populations.
Students examine the influence genes have on the survival of an organism and describe biodiversity. Students simulate the relationship between healthy populations and healthy gene diversity of deers, and complete a "Bottleneck Genes" activity that demonstrates random assortments of genes using different colored jelly beans in a bottle.
Students explain the meaning of biodiversity. They discuss the characteristics marine reserves need to be able to protect biodiversity in a given area. They compare and contrast clustered and scattered sites.
In this evolution worksheet, students review genetic variability, gene mutations, biodiversity and adaptations. This worksheet has 22 fill in the blank and 10 short answer questions.
Second graders examine bug photos from across the world. In this biodiversity lesson, students use a field notebook to make observation of insect photos. The class gather on the floor to investigate a mock field of insects and share their discoveries.
Matching and fill-in-the-blank exercises give biology whizzes a chance to practice vocabulary associated with evolution. Terms to be reviewed focus on evidence for evolution, natural selection concepts, and some genetics words. You could use this as a quiz at the end of your introduction to natural selection.
Students practice skills essential to all scientific investigation: carefully observing and collecting data. They become field biologists in a series of hands-on activities to collect and identify specimens, and survey and calculate the diversity of plant species in their local environment.
Students explore the different types of vertebrates found in their area. In this environmental science lesson, students perform a case study on the Common Raven. They analyze data collected from research and create charts and graphs.
Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be laminated for repetitive use at stations where learners investigate adaptations, morphology, genes, and analogous and homologous structures. This is a top-notch resource to help make your class fit for survival!
Students observe intra-species variation by completing standard microbial streaking procedures. They collect data from which they draw observations and complete a worksheet.
How many rainforests are there, where are they, and do global factors effect their locations? These are great questions that have great answers. Children in grades four through eight use several different maps to determine why rainforests occur where they do and what environmental factors cause them to grow. They examine biodiversity, soil, temperature, and precipitation maps to draw conclusions about rainforest ecosystems, then they mark all of the world's rainforests on a blank map. The lesson will lend itself well to a deep discussion on the environment, biodiversity, and habitat. Tip: This is a great research topic!
Are you thinking about taking your class to the local zoo? Kids of all ages love visiting exotic animals in order to learn about biodiversity, habitat, and animal adaptations. Here is a 44-page activity guide that provides educators with a wide variety of pre-trip activities intended to enhance the overall field trip experience. Each activity is hands on and involves reading, research, creative thinking, and collaboration to facilitate interest and a deeper understanding of the curriculum. For example, one activity provides children with the opportunity to create a cheetah diorama.
How many of your students know that even today new species are being found all over the globe? Introduce them to the amazing diversity our planet houses with a creative activity about animal variation and classification. They'll use a dichotomous key to classify nine newly discovered species, and then they'll construct their own dichotomous key based on a series of animal pictures, showcasing key animal features. Tip: Have each child create a new species of their own, and then have the whole class use the dichotomous key to classify them.
