Finally, the students will imagine a raised garden bed that has not been taken care of for 5 years and then 100 years. Ecological Succession Most of the time, when we talk about an ecosystem or habitat, we assume that it is stable and not changing very much; however, this is not always the case in nature. Research has shown that homework needs to be meaningful and applicable to real-world activities in order to be effective. The soil in chaparral ecosystems is very poor and often very rocky. At this station, students will be watching a six-minute video describing the stages of succession and how a forest area recovers after a disaster. This is due not only to the fact that there are more resources available but also because several plant species in chaparral biomes are so adapted to the cycle of periodic fires that their seeds are only able to sprout after a fire.Next
What type of succession will occur if a parking lot is abandoned for 1000 years? Examples of events that precede secondary succession would be wildfires and deforestation by clearcutting. In the winter following a chaparral fire, the shrubs re-sprout from their root crowns. Explain why primary ecological succession takes a lot longer than secondary succession. Some of the worksheets displayed are Ecological succession work, Ecological succession webquest answer key, Ecological succession work, Ecological succession work answer key, Reteaching activity 9 answer key, Ecological succession internet activity answers, Ecological succession activity, Succession lesson plan. Station 4: Rest Station - students can use this time to catch up on work they didn't have time to complete at a previous station or prepare themselves for an upcoming one. .Next
Students must also supply the answers. An answer key is also provided where applicable. The succession lesson includes a PowerPoint with activities scattered throughout to keep the students engaged. Each station not only offers a unique opportunity to test your students' knowledge offer an opinion, answer questions based on a video or reading, draw, etc. Students are equipped with a recording sheet passport to write their answers.Next
The assess it station is where students will go to prove mastery over the concepts they learned in the lab. Four of the stations are considered input stations where students are learning new information about succession, and four of the stations are output stations where students will be demonstrating their mastery of the input stations. The following post will walk you through each of the steps and activities from the succession lesson plan. Class Activity The teacher will show students a slide of Mt. A good example of secondary succession can be seen after a fire in a chaparral ecosystem, which is a type of ecosystem characterized by dense, evergreen shrubs; mild, rainy winters; and hot, dry summers. Actually, chaparral is a type of biome, or one of the world's major ecosystem types, that is classified according to its predominant vegetation and climate.Next
Because primary succession always starts from scratch without a significant amount of soil or nutrients and certainly without dormant roots or large numbers of seeds waiting for their chance to sprout , it takes a special type of organism to colonize and survive in the new habitat. There are 4 follow-up questions that the students will answer to show reading comprehension of the subject. Station 1: Get Hands-On — using their creative skills, students are required to draw or build. Your visual students will love this station. Not only will the number of thriving annual plants be higher after a fire, but the number of species will also be significantly higher. Let's use the example of a retreating glacier in Alaska to look at how primary succession occurs. There are two basic types of ecological succession, which are categorized mainly based on how many nutrients - or lack thereof - are already present in the soil after the disturbance.
Simply print the cards, lay them out around the room and you're all set. These small plants then begin to be replaced by shrubs and small trees, which in turn give way to alder and cottonwood trees some 50 years after the glacier retreated. Station 3: Explain yourself — students write down an opinion to a question in paragraph form. Some questions include: After a forest fire, what pioneer species would move into the area first? Students will analyze a set of cards and place them in order by stages of primary succession. However, the shrubs are slow-growing compared to annual species, so in the winter following a fire, the predominating vegetation will be soft-leafed annual plants that have an unusual amount of nutrients available to them in the form of ash from the burned vegetation as well as an abundance of sunlight without a canopy of bushes covering them.

Lesson Summary In summary, ecological succession is the process by which the species structure of an ecological community changes over time.
Student Activity The teacher will show a YouTube video using the provided link about the eruption of Mt. Sometimes the changes are caused by human activities, such as logging, dam building, and agricultural use. When the weather becomes dry, the annual plants dry up and die, which leaves only the woody shrubs and the occasional evergreen tree as the only live plants in the summer. Helens using the provided PowerPoint. Secondary succession is succession that begins after an event clears the community but leaves the soil intact.Next

Product Description This fully editable Lab Station on Ecological Succession is meant to get your students out of their seats and engaged in the content. The predominant vegetation in a chaparral ecosystem consists of woody evergreen shrubs. Each lesson is designed using the 5E method of instruction to ensure maximum comprehension by the students. The organize it station allows your students to place cards describing primary and secondary succession into the 2 different columns. However, the chaparral shrubs can re-sprout from their root crowns, so it only takes them a few years to re-establish themselves as the dominant vegetation. What role do lichen and mosses play in succession? The first organisms that colonize the new habitat and make up the are mostly lichens and mosses.Next
You can test out of the first two years of college and save thousands off your degree. Each station comes with a description card while some also contain more detailed instructions, a reading, questions to answer, etc. Small annual plants are also common but can only grow and survive during the rainy winter months. Typical animals found in chaparral ecosystems include deer, small rodents and birds, lizards, snakes, and, of course, insects. After soil is created by the mosses and lichens, grasses and small plants begin to colonize and dominate the habitat. In either case, if the change is severe enough to strip away the existing vegetation or expose a new landscape, species will colonize the disturbed area and then likely be replaced by other species. The combination of the hot, dry summers and abundance of dry vegetation makes chaparral ecosystems prone to fires.
