Material
Replicards
The replicards were \(7 \times 7\) square grids (of size 7 cm \(\times\) 7 cm), printed on thick paper. The X marks on the cells were drawn by the students using pencils.
We have made a PDF file containing blank square grids and grids with the three different patterns to be printed if needed.
Simulations
The code was written in Python and is available at https://github.com/eliamascolo/replicards.
Teacher slides
Suggested slides to present after the Replicards activity to contextualize and connect with biology the concepts “discovered” by the students during the activity. [Slides]
