In this neuroscience activity, learners conduct a simulation to demonstrate how multiple incoming signals influence the action of neurons.

In this activity about the baroreceptor reflex (BR) arc (page 123 of the PDF), learners discover the importance of maintaining adequate arterial blood pressure through a role playing exercise.

Somatic Cell Nuclear Transfer (SCNT) is a cloning method that involves transferring a nucleus from a somatic cell of the individual to be cloned to an enucleated egg.

The purpose of this lab activity is to demonstrate (through simulation) how DNA fingerprinting (or DNA profiling) might be used to solve a crime.

In this outdoor activity, learners review the parts of the synapse and their functions by playing a game.

Role-playing the parts of chromosomes and centrioles, learners use large chromosome models and nylon cords (spindle fibers and cell membranes) to walk through the processes of mitosis and meiosis.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

This activity is about collecting and analyzing DNA as part of a criminal investigation.

In this activity, learners play a game that models what happens as stem cells differentiate into different cell types.

In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.

In this biology activity, learners use plastic pipettes to cut wells into the solid gel layer of agar in petri dishes and place solutions of simulated antigen and antibody preparations into the wells.

This activity (on page 2 of the PDF under SciGirls Activity: Forensics) is a full inquiry investigation into how hairs from a crime scene are matched to suspects.

In this kinesthetic activity, learners move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.

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

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this activity about neuron/target muscle recognition (page 44 of the PDF), learners arranged in two rows facing away from each other use string to simulate neural development.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause

In this activity, learners examine antibodies and antibody recognition using a model.
