Photocopy these ten replicards to make worksheets to provide twenty additional exercises using our vinyl card set, Element Knowledge (see above). After completing an Element Knowledge card, a child can duplicate the exercise by recording the answers on these worksheets (8½" x 11"). The repetition of writing down the element names and symbols will strengthen recall and understanding of ten associated groups of elements. Children can keep their worksheets as a record of their work, and can use them to share their element knowledge with others.
