I am currently in love with datanuggets.org, if you can be in love with a website. It features current, engaging scientific research and the data the scientist collected. Students read (or in some cases can see a video) about the the data, and then work with the numbers to decide what claims they would make. There are several levels of math to choose from, and several types of data analysis for each topic, so you can use what your students need, from elementary school through college! Who wouldn’t want to dig into data on sticky-footed lizards, sexy-smelling birds, and death-defying fish. You can even search by map to locate research being done near you.
This is an incredible resource for addressing the NGSS standards dealing with data analysis and mathematics.
