  Lab: Chemical Weathering in Geology Mark as Favorite (1 Favorite)

  In this lab, students will explore the differences between erosion, weathering and chemical weathering. They will complete a lab experiment that simulates chemical weathering on 4 different types of rocks. They will also learn how to use the Mohs Hardness Test to analyze the results.

• 

  Separating Mixtures, Interdisciplinary, Electromagnetic Spectrum, Mixtures, Mixtures | Middle School

  Lab: Candy and Leaf Chromatography Mark as Favorite (13 Favorites)

  In this lab, students will learn that mixtures are created by the combination of two or more substances. Many colors are actually mixtures of several different pigments. Mixtures can be separated, and in this lab students will perform chromatography to separate mixtures found in candy and in leaves.
