Instruct students to work together to do preliminary research on snakes in order to discover which type of snake each individual student would like to study in depth. 4. Have each student submit a list of three snakes, in order of preference, that he or she would like to study. Then make assignments, so that there are no duplications. 5.
Long-Term Memory. A long-term memory is anything you remember that happened more than a few minutes ago. Long-term memories can last for just a few days, or for many years. Long-term memories aren't all of equal strength. Stronger memories enable you to recall an event, procedure, or fact on demandâfor example, that Paris is the capital of France. Weaker memories often come to mind only through prompting or reminding.
Doctors classify memories as either: 1  immediate memories â such as sounds, which are only stored for a few seconds. 2  short-term or recent memories â such as telephone numbers, which stay in your memory for 15 to 20 seconds; the brain can store about seven chunks of short-term information at any time.
