This file contains the materials list from every Process Activity in units at grades 3-4. The lists are organized by Life, Earth, Physical, and Process Science units. Use the lists to help plan how to obtain materials for activities you plan to teach during the school year.

The Unit Resource List identifies all the current resources within the Vertebrates unit. Use this list to plan which resources to use, to note printing or projecting, and to record other notes about each resource.

The NGSS Correlations Chart lists the key student resources within the unit, then identifies which of the Next Generation Science Standards each resource supports. The chart correlates to relevant Performance Expectations using NGSS codes, which are explained at the end of the document. Using a variety of resources will help develop student proficiency in the skills required for each Performance Expectation.
