  • In this activity, students use a physical model to investigate the effectiveness of different properties for base isolators.

    How base isolation originated

    Dr Bill Robinson of Robinson Seismic, the inventor of the lead rubber bearing, talks about how he developed the bearing while he was working with Ivan Skinner at the Department of Scientific and Industrial Research in the early 1970s.

    By the end of this activity, students should be able to:

    • understand how base isolators work
    • know what properties make an effective base isolator
    • carry out a simple science investigation.
