Secondary science: visual representations

These seven learning activities, which focus on 'visual representations' using a variety of tools (software) and devices (hardware), illustrate the ways in which content, pedagogy and technology can be successfully and effectively integrated in order to promote learning. In the activities, teachers assist students to understand ...

Interactive resource

The Circle: the frozen laboratory

Explore how Antarctic plants and animals are adapted to life in a polar environment. Look at species descriptions of animals such as penguins, whales and krill. Examine specific adaptations such as the dense feathers and layers of body fat of the emperor penguin. Compare feeding pathways within a food web. Explore the geological ...

Down to Earth: palaeotraveller

Travel back in time and see how the Australian continent has changed. For example, find out when glaciers were common on the Australian mainland. Look at maps, landscapes, living things and environments over the last 545 million years. Compare past temperatures and sea levels with those of today. Explore which forces are ...

Charles Darwin - The Australian Connection

This is a multilayered website about Charles Darwin and his important scientific expedition aboard the HMS Begale that included a visit to Australia. The website has interactive sections on Darwin’s journey, understanding weather, using longitude, evolution timeline, and coral reefs. The home page has a series of short ...

New plants from old?

This is a unit of work for teachers that uses plant breeding to explain the basics of genetics. Particular concepts covered include: the principles of dominant and recessive genes; plant breeding using these principles; the scientist Gregor Mendel, who first recognised the principles; and the intellectual property (IP) ...

Interactive Resource

Natural selection

This is an interactive resource about how changes in the environment affect both plants and animals in a simple ecosystem. Students build a dam in the middle of the field, dividing the ecosystem in half to illustrate the affects of geographic isolation. They watch as the grass and then the rabbit populations in that region ...

Interactive Resource

Variations and adaptations

This is an interactive resource about how climate can affect ecosystems. Students discover that variation in plants allows some varieties to survive in near-drought conditions. Next, students learn that different types of rabbits prefer to eat different varieties of plants. Students make the connection between rainfall ...

Interactive Resource

Mystery plant adaptation

This is an interactive resource about how species are adapted to their environments and that variation in a species can help the species adapt to changes in the environment. Students explore a virtual field model with light levels that vary smoothly from top to bottom. A single type of seed grows best in the center of the ...

Interactive Resource

The virtual greenhouse

This is an interactive resource about how an organism thrives in specific environments that match its specific needs. Students explore how variation in organisms can enable them to live in different environments. For example, plants with different sizes of leaves are adapted to grow under different amounts of light. Students ...

Interactive Resource

Changes in the environment

This is an interactive resource how different species can arise from a common ancestor if different groups have different selection pressures. Students can alter a field environment by growing a chain of mountains through the field. Students are challenged to grow the mountains to their maximum height while maintaining ...

Interactive Resource

Natural selection

This is an interactive resource in which students explore natural selection by controlling an environment and causing mutations in rabbits. Students can select vary environments, selection pressures, mutations and associated genetics, and then observe the populations change. This interactive resource is supported by tips ...

Interactive Resource

The predator prey relationship

This is an interactive resource about how selection pressure can lead to a change in the characteristics of a population. Students explore the effect of predation on a prey population. At first students explore protective coloration, then how the color of the rabbit population changes as the environment changes over time. ...

Interactive Resource

The virtual field

This is an interactive resource about life cycle of organisms, variation within a species, and heritability of traits. Students explore the variation that exists in a population of organisms. They plant different seeds in a field with a gradient of sunlight. Their seeds survive the winter and grow into plants the following ...

Interactive Resource

Mystery plants mystery

This is an interactive resource about intraspecific differences and how variation in a population can help a species adapt to living in different environments. This activity explores student understanding of variation and inheritance. Students are then challenged to produce a crop of plants that can grow everywhere in a ...

Interactive Resource

The virtual ecosystem

This is an interactive resource about how organisms with similar needs compete with one another for resources. This activity introduces students to the idea that all living organisms must compete for food. Students control a rabbit in a field with edible plants, at first alone, and later joined by computer-controlled rabbits. ...
