Natural selection lab- phet simulation designing the experiment in this lab you will be controlling the mutations and environment of a population of rabbits. The process of natural selection essay 781 words 4 pages natural selection is the process in which heritable traits that make it more likely for organisms to survive and successfully reproduce become more common in a population over successive generations. After adding the selection factor let the simulation run up to the 10th generation at the beginning of the at the beginning of the 4 th , 7 th , and 10 th generations , pause the simulation and count the populations. Hungry wolves: natural selection at work what will happen if you click food, and restart the simulation with one bunny 4 write a.
Title bunny population growth: description i was first introduced to this simulation during a nmsi training i love the simulation and will definitely use it again when teaching natural selection (which will be great because the kids will already be familiar with it), however i wanted to find a way to adapt it to focus more on population growth. Explore natural selection by controlling the environment and causing mutations in bunnies. The chips are down: a natural selection simulation introduction the process of natural selection occurs because organisms vary in their heritable characteristics, and because some variants survive and reproduce better than others.
This interactive simulation allows students to explore natural selection in bunnies by controlling factors in the environment (equator or arctic environment), selection factors (wolves, food), and characteristics of the bunnies (fur color, tail length and teeth length) the bunnies in the default. Choose which by represent the natural selection in real life the fail part is maybe on the exact amount of the animal that won't be match with the real life situation. Simulation run for another 3 or 4 generations • use the population numbers from the chart to get you numbers for the table, remember you can zoom in and out on the chart to get more accurate reads. Natural selection activity (natural selection game)this is a comprehensive, math-based game of natural selection it is recommended for high school biology or advanced middle school students represent a population of leopards that have a total of 6 genetic variants among them. In this lesson, students conduct a laboratory simulation to demonstrate the relationship between gene frequencies and natural selection then, students learn the principles of natural selection and relate them to the lab activity.
The evolution lab is an online natural selection simulation it works well with students working independently at computers or using a projector to show it to the class it works well with students working independently at computers or using a projector to show it to the class. Natural selection phet simulation science and maths by primrose kitten the best way to revise is to get your hands on the past papers and marks schemes (freely available on the exam board. Natrual selection phet simulation by, jenna white and abbie moore hypothesis 1 (phenotype a):if the brown bunnies are living in the arctic, then they will be less likely to survive when the wolves are hunting because they are brown and will not blend in easily hypothesis 2 (phenotype b): if the. Natural selection simply stated that within any population with variation there would be a struggle for existence and that the environment, be it available food, predators, climate or geography would select for the most favorable adaptations. Add the (natural) selection factor of food after 3 generations of offspring appear experiment c add a friend and a long teeth mutation to the bunny population.
Natural selection, the differential survival and reproduction of individuals was first proposed by darwin as the mechanism of for evolution although other factors have since been found to be involved in evolution, selection is still considered an important mechanism. Let the simulation run until for a while to see what happens add the (natural) selection factor of food and let the simulation run for a while write an explanation of what happened to the population of bunnies in this experiment. Introduction to selection: dog breeding in the first chapter of on the origin of species, darwin described how plants and animals have been bred to have desired characteristics and used such artificial selection as an analogy to introduce how natural selection works in nature. Natural selection simulation gary morris exploration 1 what are some interesting things that you have control over in the simulation predators, food, the environment, a few selected genes (fur, tails, and teeth) 2. Charles darwin discovered and developed this evolutionary mechanism called natural selection it basically stated that if there existed variation in population there would be a struggle of survival.
This is a simulation displaying natural selection with bunnies to start, you must choose the different genes and what habitat you want your bunnies to live in (arctic, equator) then click add a friend to add a bunny and get the simulation going (you cannot modify the genes of the friend. Revised spring 2010 background in this lab, you will simulate natural selection in a small population of wild rabbits evolution, on a genetic level, is a change in the frequency of alleles in a population over a period of time. Natural selection results in evolution, which is the changes in allele frequency it is the basic mechanism of evolution first step in natural selection is variation in traits of the organism, next will be a differential reproduction. Bio 11 natural selection essay natural selection lab- phet simulation select a rabbit without the mutation but with parents or grandparent with the.
A humorous but powerful tool for simulating evolution watch a trait evolve and experiment with the effects of mutation rate and the strength of selection this activity shows all the steps of natural selection in entertaining style, but generates real simulation data that can be exported or printed. What are 3 other (natural) selection factors which effect animal populations in the real world 12 if a bunny population was forced to move to a desert environment, how might natural selection have an effect on the population.
lydia berehe the natural selection of bunny simulation practical 8, march 2014 introduction background information charles darwin discovered and developed this evolutionary mechanism called natural selection. Activity 1: breeding bunnies in this activity, you will examine natural selection in a small population of wild rabbits evolution, on a genetic level, is a change in the frequency of alleles in a.
