Battle of the Beaks- This lab is always a hit! Discuss with your group which birds are more likely to be most fit and least fit in each new environment. Teacher questioning and support of students is dependent on student background knowledge of the concept and their familiarity with simulations. “ For the past three years I have had a chromebook cart and my students have been unable to use it. There is an option to introduce mutations, which causes bunnies with brown fur, long tail, or long teeth to appear. • What variables are you able to manipulate in this simulation? Check out the worksheet that goes along with the game (courtesy of Mrs. Theresa Hartz) Check out another worksheet that goes along with the game, courtesy of Ms. Julie Olson! NOTE: I gave this 1 Star because this interactive CANNOT be used by students on chromebooks or iPads (unless they have a java emmulator)! Using your knowledge of natural selection, explain how extinction occurs. Peppered Moth. NGSS Science and Engineering Practices: ... Repeat the simulation, but this time place the beans into a new environment composed of wild rice. The Artificial Selection via Selective Breeding learning objective — based on NGSS and state standards — delivers improved student engagement and academic performance in your classroom, as demonstrated by research.. Scroll down for a preview of … Teachers should monitor for student understanding throughout the activity, and use some form of large-group share-out to make sure that all students are making progress toward the performance expectation. Natural Selection is the scientific theory that organisms are more likely to pass on traits that increase chance of survival. What happens if you never “add a friend?? Activity: Simulate Natural Selection . Does Not Work on Chromebooks / iPads, Reviewed by: Bob B (Aliso Viejo, CA) on 5/30/2019 11:02:32 AM. In this simulation, students take on the roles of crab-like predators that have variations in the shape of their "claws." This simulation provides students with the opportunity to manipulate and explore the interaction of factors leading to evolution, and observe how natural selection leads to adaptation, i.e. These lesson plans are from authors independent of the authors of the simulation. Students will master the concepts of evolution by natural selection as they become predators in this lab simulation. These questions/prompts are adapted from a related resource “Quakers and Cottontails” https://www.nms.org/Portals/0/Docs/FreeLessons/BIO_Quackers%20and%20Cottontails_web.pdf. Over time, species develop beneficial traits called adaptations. Introduce the Hardy-Weinberg principle of gene frequency equilibrium with this “Breeding Bunnies” lab. Instead, after students describe what is happening to the populations of bunnies as they run different trials with different settings, teachers should ask what that means, and ask students to collaboratively develop and defend an explanations based on evidence they collected when running the simulation. What happens if you never “add a friend?? Activity 11 Natural Selection. Natural Selection—Lesson 2.1—Activity 2 Reproduction in the Sim (continued) Parent color-trait level Parent color-trait level Offspring color-trait level Trial 1 Trial 2 Ostrilopes with adaptive traits: • Select and follow an ostrilope that blends into its … • Add a friend. While students have not developed the model underlying the simulation, they can use it to investigate factors (the potential for a species to increase in number, the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, competition for limited resources, and the proliferation of those organisms that are better able to survive and reproduce in the environment) that influence the process of evolution. Teachers need to select appropriate pedagogical strategies from their own repertoire to encourage students to express their thinking and present their ideas to others for peer and teacher feedback as they are working through the simulation. And “The Chips Are Down” is yet another natural selection simulation. While students have not developed the model underlying the simulation, they can use it to investigate factors (the potential for a species to increase in number, the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, competition for limited resources, and the proliferation of those organisms that are better able to survive and reproduce in the environment) that influence the process of evolution. (If teachers are using the Quaker portion of the NMSI lesson plan as well, it is important to discuss the limitation of the Quaker simulation, so students do not walk away with misconceptions). Natural Selection and Adaptations Adaptation Simulation This adaptation simulation from The Science Education for Public Understanding Department at UC Berkley is an amazing tool for teaching how organisms change over time and how those changes affect the population. The graph at the bottom of the simulation will show that bunnies with long teeth seem to have an advantage when food is a selection factor. Learn how Dr. Kettlewell put natural selection to the test. Teachers should spend considerable time working with the simulation prior to teaching students. • What variables are you able to manipulate in this simulation? How to Play. Quick summary: In this activity students will model ‘natural selection’ by using different utensils to pick up food. The theory of natural selection was explored by 19th-century naturalist Charles Darwin. • What happens to the population sizes of the two phenotypes after several more generations? Free access - The right to view and/or download material without financial, registration, or excessive advertising barriers. You will explore how this population changes over time in the southwest. You have one minute to eat as many moths as you can. Explain why you think this occurred? This review is limited to reviewing the PHET natural selection simulation, and not any of the lesson plans from outside authors. Watch a trait evolve and experiment with the effects of mutation rate and the strength of selection. This will give you a snapshot of the major changes in the bird populations and the environment during that time. Then you will explore how the population evolves over long time periods in various environments on other areas on the island. Battle of the Beaks- This lab is always a hit! Teachers should embed this simulation into their instructional sequence where they feel it best fits. The simulation itself does not come with instructions or a lesson plan. 3. Dr. Kettlewell. The teacher should use questioning strategies to help students understand cause and effect relationships within this simulation. You save the state of your simulation and restore it within 30 days. Their light wings are “peppered” with small dark spots. Click on the link above to go to the Natural Selection simulation. Dr. Kettlewell. Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects. In Primer‘s fifth video on evolution, Justin Helps creates a blender and python-powered natural selection simulation, testing for variations on food availability along with the creatures’ speed, sizes, and their ability to sense food. Teachers should embed this simulation into their instructional sequence where they feel it best fits. Light Forest. Natural selection in action. Guide the bird to the moths. The Cottontail portion uses the PHET simulations. See the natural selection blog post for additional discussion of the activity. This simulation gives students an opportunity to observe and describe how the increase in number of bunnies (“add a friend” in the simulation starts the bunnies reproducing), genetic variation of individual bunnies (click on mutation in the simulation and then observe the phenotype of the bunnies populating the environment), competition for food and predation by wolves leads to the proliferation of those bunnies that are better able to survive in the environment. Let the simulation continue to run until it stops, and then discuss what happens. Check out the worksheet that goes along with the game (courtesy of Mrs. Theresa Hartz) Check out another worksheet that goes along with the game, courtesy of Ms. Julie Olson! • Start the simulation by clicking the “PLAY” button. When you “add a friend”, the two bunnies will start to reproduce. Watch a trait evolve and experiment with the effects of mutation rate and the strength of selection. You will begin by selecting three birds that will represent phenotypes for several traits in one population that lives in the southwest portion of the island. “Quakers and Cottontails” is published by the National Math and Science Initiative (NMSI). Natural Selection Simulation. Due to harsh conditions food becomes limited. What happens to the population sizes of both phenotypes over the next 10 generations? An example question to investigate with the simulation found in the Cottontail lesson plan is: “A population of short-toothed and long-toothed bunnies is living in the Arctic. Instead, after students describe what is happening to the populations of bunnies as they run different trials with different settings, teachers should ask what that means, and ask students to collaboratively develop and defend an explanations based on evidence they collected when running the simulation. a population of bunnies suited to survive and reproduce in the environment that students selected by manipulating the settings. Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment. Natural Selection Activity.docx - Exploration Bunnies are taking over the world Introduction In 1778 the First Fleet a group of English citizens arrived. This simulation gives students the opportunity to see what happens to the phenotypes of bunnies over several generations when manipulating selection factors. Topics Covered: Natural selection, variation, adaptation, selective pressures, evolution, directional selection, stabilizing selection, disruptive/diversifying selection, fitness, etc. The questions in the first section introduce students to the basic process of natural selection, including key concepts and vocabulary. Play Game. For example students should articulate that when a mutation occurs that provides individual bunnies with the advantage to blend into the background, they are more likely to not be eaten by the wolves, survive and reproduce, which over many generations leads to a higher proportion of bunnies with a fur color that blends into the background. To help students learn, in a more concrete way, how natural selection operates, I came up with an activity that simulates evolution by natural selection. This simulation gives students the opportunity to see what happens to the phenotypes of bunnies over several generations when manipulating selection factors. Simulate natural selection with the “Candy Dish Selection” lab. Activity 1 Our Global Community Activity 2 Life in Other Countries Activity 3 Sustainability Case Studies Activity 4 Ecological Footprint Activity 5 Jaffrey City's Problem Activity 6 Jaffrey City's Master Plan In this simulation, students work in groups of three instead of following SEPUP’s 4-2-1 cooperative learning model. A humorous but powerful tool for simulating evolution. “Quakers and Cottontails” is published by the National Math and Science Initiative (NMSI). No guidance for differential instruction is provided by the resource. This illustrates for students that the differential survival and reproduction of bunnies in a population that are better camouflaged leads to an increase in the proportion of these bunnies in future generations and to a decrease in the proportion of bunnies that are not well camouflaged. Teachers should make sure that students do not just “play” with the simulation, or just “observe” what happens. At that time I had a pod of pc's and my students could use it. Like most moths, This simulation provides students with the opportunity to manipulate and explore the interaction of factors leading to evolution, and observe how natural selection leads to adaptation, i.e. PhET Simulation - YouTube • Add the (natural) selection factor* of wolves after F3 offspring appear. This illustrates for students that the differential survival and reproduction of bunnies in a population that are better camouflaged leads to an increase in the proportion of these bunnies in future generations and to a decrease in the proportion of bunnies that are not well camouflaged. Use of the simulation provides opportunities to address the practices of using a model, planning and carrying out investigations, and analyzing and interpreting data, as well as describing the cause and effect relationships that are part of the mechanisms of natural selection. • Teachers should make sure to include a discussion on the limitations of the simulation in comparison of what might happen in the real world when students share their evidence-based explanations. Many students can recite a definition of natural selection, but they may have trouble visualizing how the process actually works. The simulation provides students with the opportunity to visually observe how for example, changing the environment (arctic vs. equator) over time leads to a population dominated by bunnies that are well suited to survive in that environment. Making it feel like you're actually s their environment or go extinct. These can be body structures, processes, or behaviors. Teacher questioning and support of students is dependent on student background knowledge of the concept and their familiarity with simulations. Click on the moth to eat it. • Teacher should encourage students to plan their investigation (think about how to run the simulation, so that they can collect data that answers their question), create a data table to keep track of the number of individual bunnies with the two phenotypes in each generation, and graph their data for an additional visual representation. Depending on where in the unit teachers are when using this simulation, the following directions and prompts can be helpful in supporting students to make progress toward meeting the Performance Expectation. The Natural Selection Simulation App allows users to simulate natural selection on a population of bouncing balls, or individuals, right at their fingertips! In what ways did this activity model natural selec-tion well? (3 reviews), 1 “ This simulation supports instruction and learning for all students by providing students with the opportunity to control a simulation that models a real world scenario of bunnies with different physical characteristics surviving in different environments. Scavenger Hunt: Simulating Natural Selection. 1. Natural Selection. 8. Do you have a suggestion for improving NGSS@NSTA? AlthoughDarwin was unaware of it, remarkable examples of evolution, which might havehelped to persuade people of his theory, were in the countryside of his nativeEngland. Experiment B • Add a friend and a brown fur mutation to the bunny population. Menu. Extension Activities: 1. 2. Examples of evidence could include mathematical models such as simple distribution graphs and proportional reasoning. The teacher should use questioning strategies to help students understand cause and effect relationships within this simulation. The simulation is straightforward to use and provides numerous ways for students to manipulate it. Take a moment and let us know what's on your mind. In Primer‘s fifth video on evolution, Justin Helps creates a blender and python-powered natural selection simulation, testing for variations on food availability along with the creatures’ speed, sizes, and their ability to sense food. Teachers should keep in mind that simulations have benefits and limitations, and that is that important to not exclusively teach natural selection through simulation, but also use data sets from field work, or other real-life demonstrations. For example students should articulate that when a mutation occurs that provides individual bunnies with the advantage to blend into the background, they are more likely to not be eaten by the wolves, survive and reproduce, which over many generations leads to a higher proportion of bunnies with a fur color that blends into the background. One of his difficulties in demonstratingthe theory, however, was the lack of an example of evolution over a short periodof time, which could be observed as it was taking place in nature. Comments about Including the Disciplinary Core Idea Natural Selection In this simulation you will investigate populations of birds living on an island. The traits that positively affect survival are more likely to be reproduced, and thus are more common in the population. Students should be working on this simulation with a partner, so they have the opportunity to discuss what they are observing, what questions they could be investigating with this simulation, how to display and analyze data, and how to write an evidence-based explanation answering their questions. What aspects of natural selection did the simulation not include? New Game. Using a simple machine learning genetic algorithm, this simulation demonstrates how populations evolve towards surviving as long as possible, with the player acting as the … Using the Simulation to Investigate Natural Selection In this minds-on, hands-on activity, students develop their understanding of natural selection by analyzing specific examples and carrying out a simulation. Describe what happens to the bunnies this time. The questions in the introductory section introduce students to the basic process of natural selection, including key … The simulation in the next part will stop every 50,000 years beginning at 500,000 years and ending at 1,000,000 years. Welcome to the Natural Selection Simulation! These questions/prompts are adapted from a related resource “Quakers and Cottontails” https://www.nms.org/Portals/0/Docs/FreeLessons/BIO_Quackers%20and%20Cottontails_web.pdf. • The teacher can provide a question for the students to investigate, or students can develop their own question. Predators of the peppered moth include flycatchers, nuthatches, and the European robin. All of these connections require that the teacher purposefully facilitates students’ use of the simulation, so that students make meaning of what they are observing. Explain This review is limited to reviewing the PHET natural selection simulation, and not any of the lesson plans from outside authors. The simulation starts you off with only one bunny. The user can also edit genes (select whether the mutation for fur color, tail length and teeth length is dominant or recessive). HS-LS4-2 Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.
