This resource turns evidence from element into a complete, ready to use review for Grade 9-12 earth science, covering the same NGSS standard from three different angles.
Among the ninety questions, students will see prompts such as "Which observation has been crucial for our understanding of helium abundance?", "Why is hydrogen considered the most abundant element in the universe?", and "The abundance of which element is critical for understanding the formation of stars?"
Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
This set is part of a NGSS aligned earth science unit. The unit also covers the Big Bang Theory, Cosmic Microwave Background, Redshift and Expanding, Formation of Galaxies, Tools of Cosmic Observation, and Dark Energy and Accelerated, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 9-12 earth science classes, and for review at any point in the school year. This set is aligned to NGSS standard HS-ESS1-2.
