2 What Is Matter?
39 THE CUNY HSE CURRICULUM FRAMEWORK SCIENCEUNIT 2: what IS matter ? what Is Matter? 2 lesson PlanNOTE TO THE TEACHERThe first half of this curriculum is devoted to matter . It covers what matter is (and isn t), what some of the properties of matter are, how you can change the phase of matter , and finally ends with atomic theory: that all of matter is made up of atoms. Once they have this, you can discuss how the structure of atoms determines if atoms will participate in chemical reactions and join together to form molecules, which in turn form proteins and other macromolecules, which in turn form plants and animals. Without chemical reactions, our whole world would just be a soup of lonely atoms. In this lesson , we focus on what matter is. matter has a formal science definition as anything that has mass and takes up space (or has volume). This lesson covers matter , mass, and volume in some depth. You might also add that all of matter is made up of particles, but we ll also get that in future lessons.
When we taught this lesson recently, we used kitchen scales to weigh one-inch density cubes, which have the same volume, but have different mass because they are made of different materials. The scale gave students a tangible way to talk about mass, which is measured in ounces or grams. Pocket kitchen scales are now available for $10-20.
