This activity invites students to measure the efficiency of solar cells as they convert sunlight to power. 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-IDA003896

This activity invites students to investigate why, when you touch a variety of materials, some will seem warmer or colder than others, even when they're at the same temperature. The activity includes a list of tools and materials required, what to do and notice, an explanation for the underlying science of what students ...

• 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-IDA003901

This activity invites students to use a giant cell (a de-shelled chicken egg) to explore the comings and goings of cellular substances. 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 suggestions for further activities.

• TLF-IDA003903

This activity invites students to experiment with a frozen water balloon and learn about water chemistry, phase changes, and density. 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 suggestions for further activities.

This activity invites students to make a sound system with a coat hanger and a string, producing musical sounds that only they can hear. 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-IDA003914

This activity invites students to use copper tape and surface-mount LEDs to make creative circuits on a flat surface, like a piece of paper. Students can make light-up greeting cards or create three-dimensional pop-up paper sculpture that have working lights in them. The activity includes a list of tools and materials required, ...

• 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. ...

This video introduces the National Earthquake Alerts Centre. The video explains that earthquakes are detected by a network of seismometers; each station sends seismic information for analysis and checking by seismologists on duty. The video describes the types of wave forms in earthquakes and the sequence of events in ...
