Adult-Child Communication: A Goldmine of Learning Experience

Children are constantly learning and experiencing new things. Each time they learn a new fact or skill, they are building on—and adding to—their existing knowledge base. Good language and literacy skills are valued around the world, and those skills are developed, like everything else, through practice. Whether through oral storytelling, play and conversation with older children, or interaction with adults, children are building their literacy skills. In this article, the authors encourage caregivers and families to see learning opportunities everywhere and to foster learning through conversation. They provide examples, ideas, and scenarios to demonstrate how language acquisition and knowledge building occur in everyday situations and how adults can converse with children in ways that enhance learning

Deglacial water-table decline in Southern California recorded by noble gas isotopes.

Constraining the magnitude of past hydrological change may improve understanding and predictions of future shifts in water availability. Here we demonstrate that water-table depth, a sensitive indicator of hydroclimate, can be quantitatively reconstructed using Kr and Xe isotopes in groundwater. We present the first-ever measurements of these dissolved noble gas isotopes in groundwater at high precision (≤0.005‰ amu-1; 1σ), which reveal depth-proportional signals set by gravitational settling in soil air at the time of recharge. Analyses of California groundwater successfully reproduce modern groundwater levels and indicate a 17.9 ± 1.3 m (±1 SE) decline in water-table depth in Southern California during the last deglaciation. This hydroclimatic transition from the wetter glacial period to more arid Holocene accompanies a surface warming of 6.2 ± 0.6 °C (±1 SE). This new hydroclimate proxy builds upon an existing paleo-temperature application of noble gases and may identify regions prone to future hydrological change
