Sentient Skills Science: What Makes Some Memories So Memorable? 

A list of words is read aloud and participants are then asked to write down (or recite) as many words as they can remember. Usually, people remember the beginning and end words on the list. A variation on this is to disrupt memory with a simple cognitive task before asking participants to remember words and observing the effect on memory. Following this exercise, a discussion of the way memory works is appropriate.

Side-Dominant Science: Are you Left- or Right-Sided?

A simple series of tests will help children determine the sidedness of the hands, feet, eyes and ears. If family members are present, children can see if handedness runs in families, and a chart on the wall can demonstrate if more people are right or left dominant.
