GRACE:Tracking Water from Space
July 22, 2014
GRACE (Gravity Recovery and Climate Experiment) is a NASA mission that uses a pair of satellites to measure Earth's gravitational field. By regularly measuring changes in the gravitational field, scientists can indirectly track the motions of large masses of water. The GRACE satellites began orbiting in March 2002. They orbit once every 90 minutes, taking 30 days to cover the entire Earth. Since the movement of water can be detected on this time scale, GRACE's ever-growing data set is revealing long-term changes in Earth's water and its relationship to changing climate.
Scientists are just beginning to analyze the data that GRACE has gathered, but climate change unfolds over decades, centuries and millennia. Scientists need three to five decades of this kind of information to truly understand the behavior of Earth's water. While GRACE's satellites probably won't last that long, climate scientists hope the mission's successors will keep the water data flowing. This information will become ever more critical to the world's growing population as climate change continues.
The workshop provides strategies for how to use data visualizations and data sets from secondary research. Teachers will examine satellite data from GRACE (Gravity Recovery and Climate Experiment) for Greenland and Antarctica to better understand the impact of climate change on ice sheets. Teachers will engage in activities to increase their ability to teach about climate change and use GRACE data with their students.
Support for these resources is provided by NASA under Award No.NNX09AL93G.

NYC Teachers Chancellor’s Day Professional Development 2015: Using Museum Resources to Support K-12 Science Education
June 4, 2015
This professional day is geared for K-12 teachers who want to strengthen their ability to use Museum resources to teach science. Participants will have the opportunity to choose from a range of breakout sessions that will utilize the Museum’s digital, print, and exhibition resources to connect with the science curriculum in ways that are engaging for students.
