Jessica Marsh EDF4402 BIOLOGY EDUCATION Detailed Plan of Learning Activities CONTENTS Learning activity 1: Excursion to the Melbourne Museum Purpose & Key knowledge Activity information Resources attached separately (PDF) Learning activity 2: Darwin’s finch adaptation practical Purpose & Key knowledge Activity information Student Handout Assessment & criteria 1 Jessica Marsh Learning Activity 1: Excursion to the Melbourne Museum Melbourne Museum Darwin to DNA Self guided program. Purpose: - To get students to examine the mechanisms of evolution, the importance of genetic variation and how DNA is used to study evolution. - For students to use the range of resources provided and the knowledge they already have to find information needed to fill in their worksheets. Key knowledge This knowledge includes change in populations: gene pool, allele frequencies; selection pressures; genetic drift; natural selection as a mechanism of evolution; evidence of evolution: fossil record, biogeography, comparative anatomy; molecular evidence patterns of evolution: divergent, convergent; allopatric speciation, extinction the development of evolutionary theory hominid evolution: patterns, origin; interrelationships between biological, cultural and technological evolution; Information: Guide your students through the Darwin to DNA exhibition at the Melbourne Museum. Use the museum education resources provided to investigate the roles of Charles Darwin and Alfred Russel Wallace in independently discovering the theory of evolution through natural selection. Students consider a number of controversial issues: Who owns the genome? Should chimpanzees be classified as part of the genus Homo? Can DNA from fossils be used to clone long-extinct organisms? Are humans still evolving? Mechanisms of evolution, including genetic drift and divergent and convergent evolution, are also explored. When a group booking is made an education kit, Darwin to DNA, will be posted to your school which includes background information, pre and post visit activities and a resource list. The museum is open daily from 10am – 5pm. The school excursion will most likely take the entire day depending on where your school is located. Concession and children get free entry, though a school booking fees will apply. The school will also need to organise a bus to transport students or another way of getting the students to the museum (e.g. Public transport) Address: Melbourne Museum 11 Nicholson St Carlton, Victoria, 3053 2 Jessica Marsh Darwin to DNA Resources providedTeacher Notes: An Education Program at Melbourne Museum – Evolution. This explains the structure and purpose of the exhibition. It also includes ideas of how to use the students guide and an exhibition floor plan. Student Guide: This handout gives the students instructions on where to go and what information they need to find. They work through the handout as they move through the exhibition covering the following topics; following in Darwin’s footsteps, evolution in action, evolution of songbirds, examining DNA and hominid evolution. You can choose for students work independently or in small groups. Exhibition Notes: Includes detailed information on the following topics 1. 2. 3. 4. 5. 6. 7. 8. The History and New Theory of Evolution Evolution and Genetics Natural Selection and Genetic Variation Evolution in Action Extinction and Diversity Fossils and Evolution DNA and Evolution Evolutionary Milestones Reference: This activity idea and information about the exhibition was taken from the Melbourne Museum website. All of the teacher, student and exhibition resources can be found through the following website: http://museumvictoria.com.au/melbournemuseum/ (accessed on 7/10/09) Assessment: To assess what they learnt form the excursion you could develop a test for them to complete back at school. 3 Jessica Marsh Learning Activity 2: Darwin’s Finches Darwin’s Finch Adaptations Practical Purpose: - For students to gain an understanding of how natural selection works and how different traits can be better suited to certain environmental situations. For students to use skills in recording, analysing and graphing results Key knowledge This knowledge includes change in populations: gene pool, allele frequencies; selection pressures; genetic drift; natural selection as a mechanism of evolution; Time length: recommended 70 mins Materials: - Plastic knives, spoons and forks (approx 5 of each) Plastic cups (1 for each student) Grass area, such as an oval Beans (3 different colours, acting in the place of seeds) Graph paper Coloured pencils Tape Setup: 1. Count 100 beans of each colour and place each colour in one cup. 2. You will also need to count out 50 beans for each colour and put these in separate cups. These will be used later in the experiment 3. Each student will need an empty plastic cup to collect beans 4. Students will need to be in 5 groups according to the tool used; knife, spoon, and fork, taped thumb or hand. Method: 1. Allow students/ place students into 5 different groups with an even number of people. If there are not enough students to have 5 groups, reduce the number of students per groups. 2. Allocate each group with one of the following tools (beak adaptation); knife, spoon, and fork, taped thumb or hand. Taping the thumb removes the use of the opposable thumb. 3. Take the students to the grasses area, and group with their group. 4. To start the practical spread out the 100 beans of each colour as evenly as possible within a 6 X 3 metre area. 5. When you say “Go” then students begin picking up the beans using their allocated tools, and putting them in their cups. After about 3 minutes say “stop”. The student should then record the number of beans they collected according to the colours and the results from the other groups. 6. Students then need to calculate how many seeds (beans) were eaten (collected). They do this by subtracting the number collected from the 100 originally there to give them the number of seeds left in the grass. 7. Next, the seeds in the grass have reproduced and there is now double (randomly distribute an additional beans, an equal amount to what is in the grass). 8. Repeat step 5, and record the number of seeds eaten. The lowest seed amount becomes extinct each generation, so this is known place a zero in the box of the table. 4 Jessica Marsh 9. Continue this process for generations until only one type of adaptation is left, displaying that the rest had become extinct. 10. Student will need to hand in their group results so they can be collated with the other groups to form class data which can be used in the formal assessment RESULTS TABLES 1st Generation Finches Seeds Knife Fork Spoon Taped thumb Hand Total White -100= Red -100= Brown -100= Total 2nd Generation Finches Seeds Knife Fork Spoon Taped thumb Hand Total Fork Spoon Taped thumb Hand Total Fork Spoon Taped thumb Hand Total White Red Brown Total 3rd Generation Finches Seeds Knife White Red Brown Total 4th Generation Finches Seeds Knife White Red Brown Total Reference: This activity and assessment idea was adapted from a great activity in a lesson plan found at the following website: www.lessonplansinc.com (accessed on 7/10/09) 5 Jessica Marsh DARWIN’S FINCH ADAPTATION PRACTICAL Purpose: You are going to mimic the variation in Darwin’s finches’ beak types for 3 different types of food. You will investigate this by using certain tools in place of beaks to pick up beans which represent seeds. This practical activity looks Natural Selection and how certain populations can be better suited to an environment. Hypothesis:________________________________________________________________________ __________________________________________________________________________ Materials: - Plastic knives, forks and spoons Red, white and brown beans Plastic cups - Tape Grassed area Handout and pencil Method: 1. Get into 5 different groups with an even number of people, minimum 5 per group. 2. Your group will be given one of the following tools (beak adaptation) from the teacher; knife, spoon, and fork, taped thumb or hand. Taping the thumb removes the use of the opposable thumb. My beak adaptation is __________________? 3. Follow your teacher to the grass area, taking with you your tool, cup, handout and pencil. 4. After the teacher has finished spreading the beans they will tell you to start collecting by saying “Go”. Collect the beans with your tool and place them in your plastic cup. After about 3 minutes the teacher will say “stop”. Now record the number of beans you collected according to the colours 5. Calculate how many seeds (beans) were eaten (collected). You can do this by subtracting the number collected from the 100 originally there to give you the number of seeds left in the grass. Fill out the 1st Generation table and put these beans to the side (they are no longer needed). Tell the teacher your results, the group with the lowest seed amount becomes extinct each generation, so this is known place a zero in the box of the table. 6. Next, the teacher will distribute more beans in the grass 7. Repeat step 4, and record the number of seeds eaten. Tell the teacher your results, the group with the lowest seed amount becomes extinct each generation, so this is known place a zero in the box of the table. 8. Continue this process for generations until only one type of adaptation is left, displaying that the rest had become extinct. Fill out the nest Generation table provided. 9. Your group will need to hand in your results so they can be collated with the other groups to form class data which can be used in the formal assessment. 6 Jessica Marsh STUDENT RESULTS 1st Generation Finches Seeds Knife Fork Spoon Taped thumb Hand Total White -100= Red -100= Brown -100= Total 2nd Generation Finches Seeds Knife Fork Spoon Taped thumb Hand Total Fork Spoon Taped thumb Hand Total Fork Spoon Taped thumb Hand Total Fork Spoon Taped thumb Hand Total White Red Brown Total 3rd Generation Finches Seeds Knife White Red Brown Total 4th Generation Finches Seeds Knife White Red Brown Total 5th Generation Finches Seeds Knife White Red Brown Total 7 Jessica Marsh ASSESSMENT TASK: DARWIN’S FINCH ADAPTATIONS PRACTICAL REPORT Title: Should explain to the reader what the experiment was about Introduction: This needs to include a little bit of background information about the topic, the aim of the experiment and your hypothesis. Materials: The material section includes a list of everything that is needed to conduct the experiment Method: The method section should be written in numbered steps. Explaining what you did, in order, in past tense (Instead of ‘Sam collected 10 red beans’ you would say ’10 red beans were collected’. The steps should be written with enough detail that the experiment could be repeated by someone else. Results: This section includes; tables, number data, measurements, observations, colour changes and descriptions. This section should include a graph or a table to display the class results provided, however you should not discuss any results in the section of your report. Discussion: The discussion section allows you to talk about your results by using theoretical knowledge you already have and the observations you have made. You will be required to answer specific questions to guide your discussion; these should be answered in full sentences. You should also mention any limitation to the experiment in this section. Questions: 1. Explain possible reasons for the first adaptation becoming extinct compared to the adaptation that was best suited (adapted for survival) 2. Which colour of the seeds was eaten the least of all the generations? Why was this seed colour more fit for survival in the grass environment? 3. How would the depth of the grass affect which beak adaptation (tool) was better suited for that environment? Explain... 4. In this activity, four beak adaptations became extinct, however Darwin’s finches from the Galapagos Islands survived with many different beak types. How is this possible, how do they avoid extinction due to competition? Conclusion: This section consists of a brief summary of what the experiment taught you. You should always refer back to your aim and hypothesis, stating whether it was supported or otherwise by the results. Your conclusion should be written in full sentences, about a paragraph or two. Remember this is a scientific report so needs to be informative but concise, keep on topic and make sure you answer all discussion questions. 8 Jessica Marsh Student name: Title (descriptive) Introduction (aim, background information and hypothesis) Materials/Method (Materials and procedure written in enough detail that it can be replicated) Results (Table or graph with captions) Discussion (Discussion and analysis explaining the results and addressing the questions) Conclusion (Paragraph in which you summarize your results) Comments DARWIN’S FINCH ADAPTATION PRACTICAL REPORT (1) Needs improvement (2) Showing progress (3) Competent (4) Distinction (5) High Distinction Total Title provided little information about the experiment Provided little information, or incorrect data.
