Constructing an annotated periodic table created with interlocking building blocks: A national chemistry week outreach activity for all ages

摘要

An activity for a National Chemistry Week outreach event has been designed in which children construct a periodic table out of LEGO building bricks. During the activity, children followed simple instructions to build the symbol of a particular element onto a 5.25 in. × 5.25 in. LEGO base plate. Squares for all elements were constructed in this manner, resulting in a periodic table composed of over 6000 LEGO pieces. The finished product has been hung on a wall in the science center at Spring Arbor University. The table has unexpectedly become a unique conversation piece that allows for informal chemical education. In addition, high school students and others have added to the charm of the table by designing LEGO creations to place on the squares of certain elements. These LEGO creations are built so as to represent the element on the square on which it is placed. How the table was built, how the construction of the table was used as a hands-on activity at an outreach event, and how people were invited to build LEGO creations to donate to the table are described.
