Immunization regulations and practices vary, partly for social and political reasons. Ask at least two faculty or administrative staff members what immunizations students at your college must have and why. If you hear, “It’s the law,” ask why.

Observe three infants (whom you do not know) in public places such as a store, playground, or bus. Look closely at body size and motor skills, especially how much control each baby has over legs and hands. Also note the infant’s ability to communicate. Estimate the age in months, then ask the caregiver how old the infant is.

Many educators recommend that parents read to babies even before the babies begin talking. How would advocates of each of the three hypotheses about language development respond to this advice?

Test an infant’s ability to search for a hidden object. Ideally, the infant should be about 7 or 8 months old, and you should retest over a period of weeks. If the infant can immediately find the object, make the task harder by pausing between the hiding and the searching or by secretly moving the object from one hiding place to another. Describe your experiment in detail.
