one of the educators at the forefront of this is lauren madden, professor of elementary science education at the college of new jersey. how do you go about incorporating climate change into a classroom curriculum? >> in new jersey it is simpler than some other places, because we have standards that are required to be taught at all grade levels and subject areas, so they are developmentally appropriate and good tools for teachers to use to think about ways they can connect the climate in things they are already doing. laura: can you give examples about how lessons about climate change may change from first grade to ninth or 10th grade? >> yes, that's really important, to be developmentally appropriate, especially talking about working with young children. in the early years, it's about understanding what lives around you, what's supposed to be here when things happen seasonally. and some of the differences between the weather and climate. it's not a tough concept for a young child to understand that weather is day-to-day changes while climate happens over long periods of time. by the time
