Purpose
Explore the fascinating world of chemical reactions by investigating how substances transform through hands-on experiments. Develop models to visualize atomic compositions and analyze data to identify chemical changes. Engage in collaborative activities to deepen your understanding and document your evolving insights in a reflection journal.
Learning goals
Explore the atomic composition of molecules and understand how atoms combine to form different substances. Investigate and interpret data to identify chemical reactions and the changes in properties that occur. Develop models that accurately represent molecular structures and use these models to explain observed chemical phenomena. Enhance your ability to analyze experimental results and refine your understanding of chemical processes through hands-on activities and reflection.
Standards
- MS-PS1-1 - Develop models to describe the atomic composition of simple molecules and extended structures.
- 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.
Products
Throughout this project, you'll create detailed models that represent the atomic composition of simple molecules and extended structures. You'll also compile a reflection journal documenting your observations and evolving understanding of chemical reactions. By the end of the project, you'll present a comprehensive analysis of data showing how the properties of substances change before and after chemical reactions, demonstrating your ability to determine if a reaction has occurred.
Launch
Begin your project by conducting a simple experiment to observe a chemical reaction, such as mixing vinegar and baking soda. Document your observations in your reflection journal, noting any changes in properties and discussing whether a chemical reaction has occurred. Use this experiment to introduce the essential question: "How do chemical reactions transform substances at the atomic level?" This hands-on activity will set the stage for exploring atomic compositions and interpreting data throughout the project.
Exhibition
Organize a "Chemical Reactions Showcase" where you create and present models of simple molecules and extended structures, demonstrating your understanding of atomic compositions. Display data and observations from your experiments on the properties of substances before and after chemical reactions. Facilitate a gallery walk where you can view and provide feedback on each other's work, fostering a collaborative learning environment. Invite peers, teachers, and family members to engage with your findings and ask questions, allowing you to articulate your learning journey and insights.
