Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.

In this simulation of synapses, learners act out communication at the neural level by behaving as pre-synaptic vesicles, neurotransmitters, post-synaptic receptors, secondary messengers and re-uptake

In this activity, learners construct a cereal chain as a model of how proteins are made in the cell.

Working in small groups, learners receive a written scenario regarding a bacterium with a certain goal it must carry out.
