093-Weathered Rock Grades 4-12 $6.00
Mystery includes rock, fossil, or mineral sample and Mystery questions with teaching instructions.

SAMPLES:
— A piece of weathered rock, one that is crumbly, light-weight, rusty-looking, but that shows 'ghosts' of minerals that have been dissolved and weathered. Saprolite is perfect for this mystery.

TEACHING OBJECTIVES:
— To introduce the concept of weathering as a process of dissolving and carrying away reactive elements from the minerals in rocks
— To dramatize the idea that 'dirt' (and soil) is formed from rock that has reacted with rain
— To help students understand the relationship between weathering and the composition of the oceans
