I created this product for a middle school English language development class. It has 30 minute lessons for 5 days. The last day is designed as a speaking/writing formative assessment. It aligns with the North Carolina 8th grade Science standard: ESS.8.4.1. This unit teaches essential vocabulary students will need when studying Earth's systems and interactions. While reviewing content information, the students will be working on the ELD standards: ELD-SC.6–8 Explain (Interpretive/Expressive)
