As part of a unit on the chemistry of the brain, thinkers learn how chemicals work to transmit messages between individual neurons and how controlled substances impact the synaptic cleft. They do so by playing a dice-and-card game in...

Using a simple circuit with the battery representing the brain, future physiologists test to see which solutions conduct electrical "nerve impulses." Enlighten learners with plentiful information on electric signals in the nervous system...

Human body systems young scholars play a card game, "Locks & Keys" in order to learn that neurotransmitters carry a message from one neuron to another by fitting into a receptor site on the receiving nerve cell. While this activity...

Marijuana affects the brain differently than inhalants, which have a different effect than opioids. Elementary and middle school classes read about these drugs as well as nicotine, methamphetamine, hallucinogens, and steroids before...

Neuroscientists and biologists study how we process our senses and the impact our receptors have on our food choices. The video, part of a food science series from PBS, highlights the nerves used in eating including the taste and...

What will viewers see when they watch this video about vision? They will observe RJ and Sam hanging out during a power outage with Rookie, the dog. The boys discuss the structure of the eye (pupil, iris, cornea, lens, retina,...
