Miller and Urey experiment
In order to successfully complete the activity you need to drag only the chemicals that were present on early Earth to the flask. You will then have to decide whether or not to turn on the water heater to boil and/or turn on the spark generator. Then watch what happens in the experiment.
Uses of radioisotopes
In this activity you will you need to correctly identify the uses of radioisotopes in different industries. You will be one of a number of different industry professionals and as such you will need to identify the correct radioisotope for your industry.
Analyse the size and colour of the stars, then drag to the appropriate position in the diagram. Once you have positioned the stars correctly, you will need to answer questions relating to the stars' temperature, mass, luminosity and ultimate fate. Please note the size and colour of stars are not to scale.
