Students organize a card sort to classify matter and energy. They also show their understanding of the relationship between an atom, molecule, and macromolecule.
Students complete a probe regarding prior understanding of chemical reactions.
Students participate in an exploration where they determine the mass of reactants before a chemical reaction and then measure the mass of products after to illustrate the Law of Conservation of Mass.
Students observe signs of chemical reactions and watch a video of elephant toothpaste and complete an analysis of the reactants and products.
Students read scientific text regarding the Law of Conservation of Mass. They answer questions regarding their reading along the way and engage in a class discussion.
Students use Carbon, Oxygen and Hydrogen ping pong balls to develop a model that demonstrates the Law of Conservation of Mass.

Students use Carbon, Oxygen and Hydrogen ping pong balls to develop a model that demonstrates the Law of Conservation of Mass.
Students watch two videos and focus on energy being absorbed and released in chemical reactions. Students read scientific text about chemical reactions and energy and apply knowledge to an example chemical reaction.
Students demonstrate their knowledge of chemical reactions and the law of conservation of mass by completing a performance event and/or a formative assessment.
Students plan and carry out an investigation to determine the effect of an open versus closed system on the total mass of a system when a chemical.
In this cycle, students use models and conduct investigations to explain how energy is transferred and matter is conserved during chemical reactions. They explore signs of chemical reactions. They then consider how what they have figured out might apply to living organisms.
