This demonstration can be used to help learners visualize DNA by lysing (breaking open) bacterial cells on a slide and “stringing up” the DNA with a toothpick in less than one minute.

In this interactive activity, learners analyze seashells to explore phylogeny and evolution. Learners identify similar and dissimilar seashells to create a phylogenetic tree.

Learners practice their taxonomy skills by sorting a group of fasteners (e.g. rubber bands, buttons, paper clips, screws) into different categories.
