Lesson Title: Mars and Earth Rocks

Objectives: 1. Students will compare different rocks.
2. Students will write down their observations.
3. Students will navigate a NASA website.

CDE Science: Earth Sciences: 3. Earth is made of materials that have distinct
properties and provide resources for human activities. As a basis for
understanding this concept: 3a: Students know how to compare the physical
properties of different kinds of rocks and know that rock is composed of
different combinations of minerals. 3b: Students know smaller rocks come from
the breakage and weathering of larger rocks. Investigation and Experimentation:
4. Scientific progress is made by asking meaningful questions and conducting
careful investigations. As a basis for understanding this concept and addressing
the content in the other three strands, students should develop their own
questions and perform investigations. 4a: Make predictions based on observed
patterns and not random guessing.

CDE Language Arts: Writing: 2.0 Writing Applications (Genres and Their
Students write compositions that describe and explain familiar objects, events,
