Changes to the number of students booked and cancellations
- Please note that if the number of students you have booked changes significantly (by a decrease or increase of 5 students or more) you need to advise our Bookings Officer as soon as possible.
- Any significant reductions in number occurring within four weeks of your booked Study Day will be charged according to the number already booked as shown on your Booking Confirmation form (or faxed amendment).
- Significant decreases are important to us so that other schools can be offered the opportunity to participate in this popular Study Day, and for staffing arrangements.
- Significant additions are also important as your school may have been combined with another school in our bookings process and additional numbers may not be possible or may need additional staffing and resources to be pre-arranged.
- Teachers are responsible for supervising their students. Large groups that are split across different sessions and/or different venues must have a supervisor for each group. (Our Bookings Officer can advise you on whether your group will be split.)
- For every 10 secondary school students we provide free admission for one adult (teacher or other supervising adult).
Suggested pre-excursion activities
Our research indicates that students gain maximum benefit from their excursion if they have an overview of their program for the day.
Educators from the Royal Botanic Garden, Sydney advise that before the excursion, students should:
- become familiar with the super continent of Gondwana and the lands that were part of it 165million years ago;
- read the information on ‘Gondwana Greening’ found at www.rbg.vic.gov.au concentrating on the information from Jurassic period to present;
- revise the structure of flowers, including male and female reproductive parts.
Educators from Taronga Zoo advise that before the excursion, students should revise the following terms / concepts:
- nocturnal, diurnal, crepuscular
- behavioural, structural and physiological adaptations
- ectothermic, endothermic
- arid, temperate environments
- arboreal, terrestrial
- vertebrate animals - fish, amphibians, reptiles, birds and mammals (monotremes, marsupials and placentals)
Please photocopy the appropriate sheets for all students and accompanying adults before your visit.
What to bring
Advise students to bring:
- copies of the Student Activities for each student (Garden, Zoo and two Museum sets)
- clipboards, pens, pencils
- hats and/or wet weather gear for outside activities at the Botanic Garden and for walking between the Garden and Museum
- lunch, snacks, drinks (note – there is very little time for students to buy lunch).
Accompanying adults should also be provided with copies of the Answer Sheets, Student Activity Sheets, and these Teacher Notes.
If you have any questions please phone the Australian Museum Bookings Office on (02) 9320 6163.
After your excursion - suggested post-visit activities
Educators from the Royal Botanic Garden, Sydney suggest the following post-visit activities:
- Students can conduct a survey of plants in their own school grounds or local park to note their adaptive features for pollination.
- Using photographs from their record taking, students can accurately identify plants for themselves by navigating the Trust’s website at www.rbgsyd.nsw.gov.au and the Plant Net database on http://plantnet.rbgsyd.nsw.gov.au.
- More useful information of known species (including correct spellings of names, and distributions) can be found on NSW Flora Online: http://plantnet.rbgsyd.nsw.gov.au/floraonline.htm
- Students can Google pictures of plants using Google Images. There are many good quality photos available for study purposes.
- In depth information on the Wollemi Pine is available on the Botanic Gardens Trust’s website: www.rbgsyd.nsw.gov.au
- A useful reference book is The Greening of Gondwana by Mary White (Reed, French’s Forest. 1994).
- Create a time line showing eras on a geological time scale with the evolution of plants and when they appeared.
Educators from the Australian Museum suggest the following post-visit activities:
- Complete the post-visit questions provided in the Evolution, survival and extinction Student Activity Sheets.
- Students can share the results of their investigations with the rest of the class
- Students complete one allocated megafauna activity at the Museum and can share their investigations with the rest of the class (via a presentation or report) back at school.

Student activities at the Royal Botanic Garden, Sydney
Two sessions are conducted at the Royal Botanic Garden, Sydney:
- Evolution and Adaptation of Australian Natives – a session with a Botanic Garden educator.
- Zoomobile – a session with a Taronga Zoo educator.
Garden session: Evolution and adaptation of Australian natives
This session at the Botanic Garden focuses on the evolution and adaptations of Australian native plants.
The activities are student focused and hands on involving observation of actual plant fossils and examination of plant species growing in the Botanic Garden. Student participation and involvement in these activities provides information for completing the activity sheets on the topic.
Part 1: Biological evidence
In the Education Centre students study an animated presentation of continental plates moving over millions of years, showing how Australia was once part of Gondwana.They then examine fossil evidence of Glossopteris, flora found in Australia and other parts of Gondwana 200 million years ago.
Students then have the opportunity to measure and record observations comparing Australian conifers from the extinct to the extant. The extinct will be examined in fossils in the Education Centre.
Part 2: First hand investigation
Students visit areas of the Botanic Garden displaying Southern conifer forests and broadleaf rainforests. They record plants of these forests through first hand observation of their modern day relatives. This helps them appreciate the rise of early angiosperms and their success compared to gymnosperms.
In another first hand investigation students gather and present information about flowers of native species of angiosperms. They will identify features that are adaptations for wind, insect, bird and mammal pollination.
Zoo session: Evolution of Australian biota
The Taronga Zoomobile visits the Garden Education Centre allowing students to interact with live animals while learning about the adaptations and evolution of native Australian animals.
An educator leads the session and engages students in an interactive presentation and discussions on five main themes:
- the rise of mammals and the early record of mammals in Gondwana;
- kangaroo evolution from 55 million years ago through to present day including
- reasons for their evolution, survival and extinction;
- mechanisms for fertilisation and survival of young in the Salt Water Crocodile;
- adaptations and species variation in Australian echidnas;
- the changing ideas of scientists with reference to the Platypus.
Student activities at the Australian Museum
There are two sessions at the Australian Museum:
- Learning from Fossils – a session with a Museum educator.
- Evolution, extinction and survival – a self-guided session in the Surviving Australia exhibition.
Museum session: Learning from fossils
This session takes place in the Science Studio on Level 2 of the Museum. Students work in small groups of 4 - 5 students and conduct hands-on investigations. A Museum educator introduces the session and facilitates the group work.
The activities increase the students’ understanding of the applications and uses of biology while they work with real and cast fossil specimens and skeletal material of modern Australian animals.
There are five hands-on activities:
- The Diprotodon
- Short-faced kangaroos
- Mammal teeth
- Reconstructing animals from fossils
- Platypus evolution.
All students complete the Platypus evolution activity and one allocated megafauna activity. Students can later share their investigations with the rest of the class back at school.
Teachers should assist in facilitating the students’ learning and keeping them on task.
Museum session: Evolution, survival and extinction
This self-guided session is based in Surviving Australia, a semi-permanent exhibition located on Level 2. Within the exhibition, students focus on displays in the section Adapt or die: specialists over time.
The activities allow students to examine past Australian fauna and the contribution palaeontology makes to our understandings of past and future environments.
There are five activities:
- Meet the megafauna
- The vanishing megafauna – many died!
- The vanishing megafauna – some survived
- Investigating an extinct Australian animal
- The puzzle of the Platypus.
Teachers may choose to direct their students to complete either:
- all five activities, or
- only one or two allocated activities per group to later share back at school (allowing the students more time to explore the exhibitions).
To avoid overcrowding of the displays, teachers should ensure that their students work in small groups and organise each group to start with a different activity then rotate through the various activities. Note that not all activities take the same time to complete and some flexibility in the rotation between activities may be needed.
The Study Day is specifically designed for the Stage 6 Biology topic, 8.5 Evolution of Australian Biota.

|Students learn to:||Students:|
|1. Evidence for the rearrangement of crustal plates and continental drift indicates that Australia was once part of an ancient super continent.||
|2. The changes in Australian flora and fauna over millions of years have happened through evolution.||
|3. Continuation of species has resulted, in part, from the reproductive adaptations that have evolved in Australian plants and animals.||
|4. A study of palaeontology and past environments increases our understanding of the possible future range of plants and animals.||
