Having separated the SL activities and SL skills into difficulty levels, the next step is to create a “bank of science skills”. Each one of the skills should be available to one or more SL difficulty levels. For example, the skill area of information retrieval should be available in all the difficulty levels whereas expressing ideas is not available at the beginners’ level and the experimentation/creation of tools is only available to the two higher difficulty levels. However, the same scientific skills can get shaped to fit into the appropriate SL difficulty level. For example, the beginners may retrieve information from outside SL until they get familiarized with it, and the intermediates can make use of the notecards and collect information from their visit to a place.
