The "Next Generation Science Standards" ("NGSS") have placed an emphasis on the incorporation of engineering practices into K-12 science instruction. This article details a sequence of physical science lessons that would be part of teaching matter in the second-grade classroom. The goals of these lessons are: (1) to be hands-on…

Scientific modeling, the practice of creating models such as "diagrams, analogies, and simulations" (NGSS Lead States 2013) allows students to develop and revise their own representations of the natural world and use them to generate predictions and explanations about scientific phenomenon. Research provides evidence for elementary…

The "Next Generation Science Standards" ("NGSS") shift what it means to teach and learn science. One significant change emerges from the central role of discourse. As the practices are language-intensive and the performance expectations explain what a student should be able to do in science, every student must learn the…

English language learners (ELLs) bring a wealth of knowledge to science classrooms, yet often that knowledge is untapped by traditional instruction and assessment. As classrooms become increasingly diverse, it is critical to recognize the depth of understandings ELLs bring to classrooms to explain the scientific world around them. English language…

The vision for science education set forth in "A Framework for K-12 Science Education" (NRC 2012) makes it clear that for today's students to become the scientifically literate citizens of tomorrow, their educational experiences must help them become mathematically proficient. "The focus here is on important practices, such as modeling, developing…
