Physical and Chemical Reactions
Physical and Chemical Reactions
How can we determine if a chemical reaction has occurred, what type of reaction occurred, and what happens to the molecules within?
Critical Thinking: Students analyze experimental data to conclude whether chemical reactions have occurred and apply the law of conservation of mass.
Adaptive Perseverance: Students design and conduct experiments, adapting their methods based on outcomes and feedback.
Collaboration: Students work together to build models and devices, sharing insights and learning from each other's approaches.
What are the signs that indicate a chemical reaction has taken place?
How can we demonstrate the law of conservation of mass through a simple experiment?
How can we distinguish between endothermic and exothermic reactions in everyday examples?
Students will identify and explain indicators of chemical reactions.
Students will understand and apply the law of conservation of mass.
Students will differentiate between endothermic and exothermic reactions, providing examples.

MS-PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-5: Develop a model to show that the total number of each type of atom is conserved during a chemical reaction.
MS-PS1-6: Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.
