• TLF-IDA003917

This activity invites students to explore simple mechanical elements such as cams, levers, and linkages, while creating a moving sculpture. This activity is simple to start but may become more and more complex as students become familiar with possible motions and imagine ways to artistically decorate their contraption. ...

• TLF-IDA003898

This activity invites students to investigate how melting ice is a factor contributing to sea level rise. They explore whether the location of melting ice on Earth affects the way sea level rise occurs by making a model of seas, ice and continents. The activity includes a list of tools and materials required, what to do ...

• TLF-IDA003827

In this lesson, students participate in four tasks to develop an understanding of the properties of water, specifically how water changes when warmed or cooled.

• TLF-IDA003908

This activity invites students to engineer a bottle racer: a plastic water bottle propelled by energy stored in a wound-up rubber band. The activity includes a list of tools and materials required, assembly instructions, what to do and notice, an explanation for the underlying science of what students observe and suggestions ...

• TLF-IDA003890

This activity invites students to explore why the world gets dark so fast outside the circle of the campfire. Using simple equipment, students can investigate the inverse square relationship for light spreading out over an area. The activity includes a list of tools and materials required, assembly instructions, what to ...

• TLF-IDA003808

In this lesson sequence, students use a range of hands-on activities to explore what water is and how it behaves as it changes from ice to liquid water to water vapour. They explore the structure of water molecules and how these molecules behave when water is heated and cooled to help them to understand how the water cycle works.

• TLF-IDA003822

In this culminating activity, students use their understanding about how people use and manage water to respond to hypothetical scenarios about water shortages. In this activity, students discuss 'what if' scenarios: possible reasons for the shortages, possible consequences and ways to manage the situation.

• TLF-IDA003878

In this sequence of 15 lessons students will learn about how genetics and DNA are inherited from parents in fertilisation, as well as how DNA replicates itself.

• TLF-IDA003889

This activity invites students to explore how light is reflected from the underside of a water surface. The activity includes a list of tools and materials required, assembly instructions, what to do and notice, an explanation for the underlying science of what students observe and suggestions for further activities.

• TLF-IDA003900

This activity invites students to examine the baby plants inside the seeds we eat and explore the various structures that protect and feed a developing plant embryo. The activity includes a list of tools and materials required, what to do and notice, an explanation for the underlying science of what students observe and ...
