Exploring atoms: atom structure

See how scientists such as Ernest Rutherford have investigated the structure of atoms. Explore possible models. Fire charged particles at atoms and find which model best fits the results. This learning object is one in a series of six objects. Three of the objects are also packaged as a combined learning object.

Interactive resource

Radioactive decay

Watch radioactive decay happen at the sub-atomic level. Make predictions and analyse graphs resulting from the decay of an array of radioactive atoms in order to determine the half-life of the element. For example, find the half-life of the radioactive element used in carbon dating, carbon-14. This learning object is a ...

Assessment resource

Radioactive decay: half life

Watch radioactive decay happen at the sub-atomic level. Make predictions and analyse graphs resulting from the decay of an array of radioactive atoms in order to determine the half-life of the element. For example, find the half-life of the radioactive element used in carbon dating, carbon-14. This learning object is one ...

Interactive resource

Radioactive decay: radiocarbon dating

Use radiocarbon dating to find and compare the ages of ancient remains. Convert organic samples to gas and use a Geiger counter to measure radioactivity. Use calculations and radioactive decay graphs to estimate the age of the samples. For example, check whether a bone from 'Sthenurus', a giant kangaroo, could be younger ...
