Teachers notes
This education kit provides teachers with resources to plan a successful class visit to the 600 million years: Victoria evolves exhibition at Melbourne Museum and implement a unit of work around this topic.
600 million years: Victoria evolves brings to life the fantastic landscapes and life forms of the past. It is laid out in a timeline starting 600 million years ago. Your students will start their journey exploring early multicellular life from the fossils of Ediacara, South Australia. Students will see the real fossils alongside models and multimedia interactives of these early life forms. They will find out about fish evolution, eventually to vertebrates walking and breathing on land; see animatronic dinosaurs modelled on scientific evidence found in Inverloch, Victoria; observe multiple fossil whales to explore how these grand animals evolved from land animals into water dwellers; and listen to scientists explain their discoveries and answer the question ‘how do we know?’
This highly engaging and interactive exhibition allows students to discover how life and landforms in Victoria have changed over millennia, and how extinction events have shaped the ecosystems of today.
Themes in 600 million years: Victoria evolves link to the displays in the Dinosaur Walk exhibition, with exhibits combining geology and palaeontology to tell the story of our changing landscapes and life over millions of years.
Please note:
600 million years: Victoria evolves is at Melbourne Museum.
Melbourne Museum is open from 10am until 5.00pm each day.
Bookings are essential.
Telephone: (03) 1300 130 152.

Science
Students use time scales to explain the changing Earth and its place in space. Students distinguish ideas about the universe that have a scientific basis from those that do not. They use physical and theoretical models to investigate geological processes. They describe aspects of scientists’ work and how this has contributed to science knowledge.
English
Students express creative and analytical responses to texts, themes and issues. They critically evaluate the spoken language of others and select, prepare and present spoken texts for specific audiences and purposes.
The Arts
Students – independently and collaboratively – plan, design, improvise, interpret, evaluate, refine, make and present works that represent and communicate ideas and their purpose.

Activity 1: Prior knowledge and evolution
Objectives and VELS links
Students’ prior conceptions are a major factor affecting how and if they learn, and these can be established and addressed. This activity aims to elicit students’ prior knowledge of the topic of evolution. By identifying their conceptions of evolution, the information can be used to challenge any misconceptions. This activity links to the Science and Thinking domains of VELS.

What you need
Photocopies of the worksheet
Five boxes
Scissors
What to do
1. Give each student a copy of the worksheet and have them fill it in, stressing that the exercise is anonymous. At this stage, the point of the activity is to find out what students already know about the topic and establish the range of ideas in the classroom.
2. Set out the five post boxes on the front desk, labelling them 1 to 5.
3. Students need to cut up their worksheet and post their responses in the correct box, numbered according to the corresponding question.
4. After the students have posted their responses, split the class into five groups. Each group takes a post-box.
5. Instruct the students to sort the responses, but not judge the answers. They can bundle the ideas and see if there are some common threads.
6. On a large piece of paper, have each group summarise the common ideas held by the class for each question. Each group needs to report to the whole class on these points.
7. These posters can then be placed on the walls and used for reflection throughout the unit of work.

Activity 2: Fossilisation
Objectives and VELS links
In this activity students are encouraged to think about how the process of fossilisation happens. The activity links to the Science and Thinking domains of VELS.
e5 Instructional Model links: engage and explore
What you need
Scissors
Printouts of the images
What to do
1. Start by giving the students the Dinosaur Fossilisation sheet or the Diprotodon track way sheet. Ask the students to discuss what they see.
2. Allow the students to cut out the images and order them as they think appropriate. Next, have the students write under each image what they think is happening.
3. Have students share their thoughts on the order they created and the content in each image.
4. Each sequence represents a real fossilisation sequence that occurred in Victoria. More information about each sequence can be found at these websites:

Activity 2: Teacher answers
Dinosaur Fossilisation
1. Qantassaurus dinosaurs are frolicking near rivers edge, with a dead Qantasaurus near the water’s edge.
2. It rains, and the river expands, and washes the dinosaur in. The dinosaur’s muscles rot away and leave the skeleton.
3. The skeleton breaks up under water, and the bones settle to bottom of the river.
4. All the bones settle in river bed, and become covered in multiple layers of mud and sand, which eventually become hard and turn into sedimentary rock.
5. Millions of years pass. The river is no longer. The top surface of sedimentary rock exposed at beach and is being eroded.
6. Fossils found!

Activity 2: Teacher answers
Diprotodon track way in Victoria
1. Western Victoria, 100,000 years ago. A volcano erupts and ash falls onto the ground, and over a nearby lake.
2. Drought conditions mean that the lake has dried up, exposing the volcanic ash mud. The volcano is now dormant.
3. A Diprotodon walks across the mud to get to the lakes edge to have a drink.
4. Footprints are left behind. The drought continues, and the volcanic mud hardens, preserving the footprints.
5. Rains returns. The hardened footprints are once again covered by a lake.
6. Drought again, but now the date is 2008, and palaeontologists find the fossil footprints.

What you need
Toilet paper (the recycle toilet-paper brand Naturale has 230 sheets per roll; the Safe brand has 240 sheets).
A long corridor, hall or outdoor area
What to do
1. Start of by having each student fill in the Timeline Chart on page 13, indicating when they think the various events happened.
2. Find a place where you can roll out the toilet paper. Start with the Formation of Earth tab found on page 14, to mark the point along the paper when this happened. Then use the rest of the tabs to mark the other significant points as you roll out the paper.
3. After the class has mapped out all of the tabs along the paper, have the students reflect on their original answers on the Timeline Chart. Discuss with the students patterns they noticed, what evidence would scientists used to understand this timeline of evolution.

Activity 4: Get selected… naturally
Objective and VELS links
In this activity, students are encouraged to explore the idea that organisms with certain traits are more likely than others without these traits to survive environmental changes (or in this case, selection pressure by predation). This represents the idea of natural selection. The activity links to the Science and Interpersonal Development domains of VELS.
e5 Instructional Model links: engage, explain and explore.
What you need
Tape measure
Stopwatch and whistle
Four orange ‘witches’ hats’
Coloured chalk – four different colours, including green
What to do
1. Map out a square field on a grassy area, about 5x5m, and mark the corners with the witches’ hats.
2. Break the chalk sticks in half and randomly scatter them on the square. Each chalk piece represents a worm.
3. Organise the students into groups of three and give each group a printout of the activity sheet on page 16. Divide the tasks in each group as follows: mother bird, baby bird and the scientist.
4. Nominate a timekeeper, who times each 10-second round of ‘worm collecting’. The timekeeper uses the whistle to signal the start and end of each round.
5. The ‘mother bird’ has 10 seconds per round to go into the field to collect food for her ‘baby bird’. She can only collect one worm at a time and cannot throw the worms to her baby. The baby bird is not allowed to enter the field, but must remain at the edge of the square.
6. At the end of each round, ‘the scientist’ records the number of each colour of worm collected.
7. Play five rounds. If you have plenty of worms, don’t throw the ‘eaten’ worms back into the field at the end of each round, so the colour ratio on the field changes.
8. Discuss the results back in class. You may like students to graph the results in MS Excel. If your class completed the post-box activity, you may like to review students’ answers and revisit questions such as ‘what is meant by survival of the fittest?’ And ‘what is evolution?’

Activity 5: Survivor… dice-style
Objectives and VELS links
In this activity, students can simulate the process of natural selection by using fictional variations of Diprotodon. This activity links to the Science and Interpersonal Development domains of VELS.
e5 Instructional Model links: engage, explore, explain and elaborate.
Note to teachers:
This simulation uses probabilities based on incomplete dominance and random mating, and involves potential selective pressures. Students should have a grasp of basic terminology relating to natural selection.
Approximately 15 minutes is required for setup, 60 minutes for the simulation and 30 minutes to respond to the questions.
Please read the questions and edit to suit your students’ abilities; questions assume a unit of genetics has been completed.
What you need
Copies of each Diprotodon variation, each size backed with a different coloured card (e.g., all small Diprotodons glued to red card)
Scissors
Glue
Coloured card (three colours)
Two butterfly pins
Pens/pencils
What to do
1. Work in small groups of two to four.
2. Create and/or collect all materials required: 50 small, 50 medium and 50 large Diprotodons, spinning wheel of death, spinning wheel of life, generation table copied.
3. Create a space on the floor or on a table, and place 10 of each Diprotodon type in the space.
http://museumvictoria.com.au/MelbourneMuseum/Education/ 20
4. Place the extra animals to the side. This is ‘generation 0’. Fill in the generation table accordingly:
Generation Number of Diprotodons
Small Medium Large
0 10 10 10
1
5. Mix the animals and then randomly pair them in the space (doing it as quickly as possible or pulling them out of a hat can help this to be random).
6. Allocate one offspring for each pair, using the grid of life to determine the offspring. For example, if a pair consists of two small Diprotodons, the only possible offspring is a small Diprotodon; if the pair consists of a medium and a small Diprotodon, then the spinning wheel of life determines the offspring according to the number spun: 1 = large, 2/3/4 = medium, and 5/6 = small.
7. Add the offspring to the habitat from the extra Diprotodons.
8. Record the new Diprotodon numbers (parents and offspring) in the generation table as ‘generation 1’.
Generation Number of Diprotodons
Small Medium Large
0 10 10 10
1 e.g. 12 15 18
Life goes on and some Diprotodons don’t survive selective pressures!
9. Spin the spinning wheel of death just once to determine which animals will make it to the next breeding season.
10. Move the ‘dead’ to your extras pile as directed by the wheel. Repeat steps 5 to 10 for at least 10 generations.
Diprotodon Source: Museum Victoria
http://museumvictoria.com.au/MelbourneMuseum/Education/ 21
Think about these questions
1. Incomplete dominance involves a heterozygote showing a blend of the phenotypes of the dominant and recessive alleles. How is this demonstrated in the Diprotodon variations?
2. What might punnet squares for the matings look like?
3. What ratios would the phenotypes exhibit?
4. This simulation relies on random mating. Was it truly random? Is mating truly random in nature? Explain.
5. This simulation also restricts the number of offspring to a single child. Is this always the case in nature?
6. Which animals are more likely to have multiples?
7. Twenty generations or more have been simulated in a very short time to affect a change in the frequency of variation types (proportions of each). If the lifespan of a Diprotodon were about 60 years, with sexual maturity (ability to breed) beginning at 15 years, and pregnancies every five to 10 years, how long would the scenario of this simulation have taken? (Rough estimate only)
8. What is a selective pressure?
9. Consider the selective pressures described on the spinning wheel of death. Are they realistic selective pressures for an animal of the megafauna group? How do they relate to the theories about the megafauna extinctions?
10. Do you think the outcomes of each selective pressure are fair? Explain.
11. Convert your generation table into a line graph, using a different colour for small, medium and large. Put the number of Diprotodons on the Y-axis and the generation number on the X-axis.

Activity 6: Convergent, divergent or homology?
Objectives and VELS links
In this activity, students identify structural homologies in megafauna skeletons to illustrate evidence of divergent evolution, and functional homologies as possible evidence of convergent evolution.
e5 Instructional Model links: explore, explain and elaborate.
What you need
Coloured textas or pencils
Images of skeletons printed from this activity
Images of skeletons representing extant species
Images of skeletons representing long-extinct species
What to do
The megafauna skeletons on the following page represent three classes of vertebrates: mammals, birds and reptiles.
1. Students study the skeletons carefully and identify as many similarities as they can, colouring them on each image. For example, all three have a single thigh bone (femur), so all femurs would be coloured the same colour.
2. Once students have identified similar structures, they consider the functions of each:
a. Consider the similarities: are they the same? How do they differ?
b. Is the structure modified to suit a particular function (e.g., running)?
c. Are the species likely to have diverged from a common ancestor relatively recently? How would one tell?
d. Do they live in similar environments? How might this influence the evolution of their body structures?
e. Do they experience similar environmental pressures?
Extension activity
Analyse skeletons of extant and long-extinct species to demonstrate the longevity of successful structures. Find images at:

Activity 7: Australian palaeontologists
Objective and VELS links
This activity links strongly to Science at Work in VELS. Students describe the contributions Australian scientists have made to improve and/or change scientific knowledge. They provide two examples of the work of scientists that demonstrate different approaches to developing scientific knowledge or solving a scientific problem.
e5 Instructional Model links: engage and elaborate.
What you need
Internet connection
Data projector and screen
What to do
1. Discuss with the class what they think the work of a palaeontologist might be. Have the students make notes, or write their ideas on a board. You may want to use a ‘KWL’ chart provided on page 29. For example, what kinds of people go into palaeontology? What kinds of work would they do? What does their work contribute to our understanding of the world? Set up the room so students can watch the selected clips. You may not be able to get through all clips, so let the students choose which ones to watch.
2. Revisit the students’ ideas. Have their views changed? How did these scientists use the evidence to understand our world? Did they take different approaches to understanding the past? Has our understanding of prehistoric animals always been the same or have the ‘facts’ changed over time?
Museum Victoria palaeontology clips
Dr Tom Rich talks about finding an ichthyosaur: http://museumvictoria.com.au/melbournemuseum/discoverycentre/600-million-years/videos/finding-fossils/ Dr Erich Fitzgerald talks about whale evolution: http://museumvictoria.com.au/melbournemuseum/discoverycentre/600-million-years/videos/whale-evolution/ Peter Trusler talks about reconstructing prehistoric animals: http://museumvictoria.com.au/melbournemuseum/discoverycentre/600-million-years/videos/reconstructing-palorchestes/ Leslie Kool and Mike Cleeland talk about finding Koolosuchus in Victoria: http://museumvictoria.com.au/melbournemuseum/discoverycentre/600-million-years/videos/koolasuchus/

Activity 8: Prehistoric ‘pictionary’
Objective and VELS links
For many students, a great barrier for learning in science is its language. This activity encourages students to develop their scientific vocabulary. This activity links to the Science at Work standards of VELS. The game can be used part way through a unit, after students have been introduced to these words, as a way of reinforcing the scientific vocabulary.
e5 Instructional Model links: engage
What you need
Printouts of ‘pictionary’ cards
Scissors to cut out cards
Stopwatch
Blackboard and chalk for scoring
What to do
1. This can be played as a whole class, by dividing the class into two teams of equal numbers (A and B). Alternatively, it can be played in small groups of five, with two pairs and one person as timekeeper.
2. If playing as a whole class, the teacher chooses the first student from Team A to begin. If playing in small teams, the timekeeper gives out a word and both pairs compete at the same time. Each student has one minute to draw clues to the randomly chosen word.
3. The team members of the student drawing work together and call out their guess of the word. If the word is guessed within one minute, that team wins one point.
4. When playing as a whole class, the opposing team gets a chance at guessing the word if it is not guessed within a minute. When playing in small groups, the timekeeper may reveal the word.
5. When playing as a whole class, teams alternate turns at drawing.
6. The team with the most points when all cards are used, or when the full time is reached, is the winner.
7. The timekeeper’s call is final, regarding time signalling and the correct answer.

Activity 9: Evolution ‘slowmation’
Objective and VELS links
Students will develop their understanding of evolution by creating a ‘slowmation’ clip. Slowmation is a simple form of stop-motion animation, in which learners create animations. This links to the Science, ICT and Communication domains in VELS.
e5 Instructional Model links: engage, explore, explain and elaborate
This teaching concept was originally developed by Garry Hoban, Associate Professor of Science Education and Teacher Education, University of Wollongong, Australia. See www.slowmation.com.
What you need
Play dough, plasticine, pipe cleaners
A3 coloured paper or white paper (as background for the clip)
Digital cameras (or web cameras) and tripod (one per group is best)
Computers (with Movie Maker – standard with latest versions of Microsoft Office)
Microphones on each computer to record student’s narration
What to do
1. Organise students into groups of four and explain they will be making a one-minute animation to show how evolution occurs, using a technique called ‘slowmation’. Show the students some examples of slowmation, which can be found at:

4. Hand out a copy of the instructions (below) to students, for making objects and photographing them. Ideally, each group will have a digital camera (or webcam), a tripod and equipment to make their own clip.
5. Upload the photographs to a computer and produce the clip using Windows Movie Maker. Each group will need a computer and the instructions for Movie Maker.
6. Share the clip and ask students to reflect on the experience. How did they feel about using this method as a process to learn about plate tectonics. Did they find it was useful? Did they enjoy the process? What would make it better?

How to construct a slowmation
You can create clips using Windows Movie Maker. It usually comes free and is installed with Windows XP or Windows Vista. On a PC, Movie Maker is the movie-making program and Movie Player the video-playing program.
Taking the photographs
1. Small movements are best! Demonstrate a simple animation first on some Post-it notes and flick through them. Start small by making a simple slowmation.
2. Lay down the A3 paper, which can be coloured, and build the models on the floor, with the tripod-mounted camera looking down on the models. Make sure the models are movable and not stuck to cardboard. You can use any materials to create your slowmation, such as play dough, paper, and pipe cleaners.
3. Make sure the image size of the camera is set on ‘smallest size’, such as 640x480 pixels. If you are using more than one camera make sure that they are set on the same photo size.
4. Take the photos, moving the materials a small bit at a time between shots. For example, a one-minute slowmation needs about 100 photos.
5. Minimise text and only label key concepts, taking one photo that can be copied for a static image.
6. Connect the camera to the computer and download the photos, which should be available from ‘My Computer’. Open the ‘Removable Disk’, copy the photos onto the desktop and then disconnect the camera.
Using Windows Movie Maker
1. Click on ‘Start’, at the bottom of the PC, and click on the Windows Media Maker icon to open the program.
2. Go to ‘Movie Tasks’ on the left-hand side, then to ‘Import’ and next click on ‘Pictures’.
3. Locate the folder containing your digital images and click on first photo. Click Ctrl + A and then ‘all’ to select all. Click ‘Import’, so that all the photos appear on the photo board.
4. Go to ‘Tools’, then ‘Options’, then ‘Advanced’ and choose picture duration at 0.500; the transition should be set at 0.25. Click ‘OK’.
5. Click on the first slide and then Ctrl + A to select all. Drag the photos down to the storyboard.
6. The movie will appear in the storyboard. Play it by clicking the large arrow in the animation.
7. If you want to show it at full screen, click ‘View’ and then full screen.

Making static images to suit a narration
1. Click on the relevant photo in the storyboard and then click Ctrl + C to copy and Ctrl + V as many times as you need to keep the static image on the screen, which is important for the narration to be recorded later.
2. Use the arrows on the bottom right-hand side of the computer to find the images you want to copy and follow the step above.
3. You can rewind the storyboard with Ctrl + Q and play the storyboard with Ctrl + W.
4. You can delete any unwanted photos by clicking on them and pressing ‘Delete’.
5. You can add your own photos or those from Google Images by copying and pasting them.
Adding narration
1. Slowmations need a narration or text, but not both. It is advisable to write a script to get the best possible narration. This should have occurred in the storyboarding phase.
2. Go into ‘Tools’ and select ‘Narrate Timeline’, or click on the microphone icon above the storyboard. Make sure you click on ‘Audio device’ to select the microphone.
3. Ensure your computer microphone is working. Click on ‘Start Narration’ and stop when necessary.
4. Make sure you save and name the file.
Saving the animation
1. You can save the project by clicking ‘Publish to this Computer’ or ‘Save to this Computer’, under the ‘Finish Movie’ heading. This saves the movie as a .wmv (window media video) file, which allows it to be shared and opened on other computers.
2. Chose a movie location to suit your needs. It may be best to save it to ‘My Computer’. It must be saved as a .wmv to be uploaded to a website or shared with others. If you save under the ‘File’ menu in Movie Maker it becomes a .WMMV file, which cannot be transferred or uploaded.
