This article describes a series of inquiry-based lessons that provide English language learners (ELLs) with opportunities to experience science and engineering practices with conceptual understanding as well as to develop their language proficiency in elementary classrooms. The four-lesson sequence models how various types of instructional strategies for ELLs can be embedded through science lessons with thoughtful consideration of ELLs' diverse cultural backgrounds. The cross-curricular science lessons provide ELLs with opportunities to apply and enhance their mathematics, reading, writing, and communicating skills while investigating the properties of M&Ms.
