Purpose

Students will collaboratively design and conduct experiments to explore the chemical reactions between Alka-Seltzer and water, focusing on varying amounts to observe changes in gas production. Through live demonstrations, they will articulate their findings and engage an audience, fostering a deeper understanding of scientific processes. This experience encourages critical thinking, self-directed learning, and a sense of belonging as students provide and receive peer feedback, refining their conclusions and enhancing their scientific inquiry skills.

Learning goals

Students will design and conduct experiments to analyze the chemical reaction between Alka-Seltzer and water, focusing on measuring gas production. They will document their procedures and observations, using data to determine if a chemical reaction has occurred. Through peer feedback and self-reflection, students will refine their understanding and presentation skills, enhancing their ability to communicate scientific concepts effectively. Additionally, students will engage in critical thinking and problem-solving by exploring innovative approaches to their experiments and considering their implications within real-world contexts.
Standards
  • [Next Generation Science Standards] 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.
Competencies
  • Self Directed Learning - Students use teacher and peer feedback and self-reflection to monitor and direct their own learning while building self knowledge both in and out of the classroom.
  • Academic Mindset - Students establish a sense of place, identity, and belonging to increase self-efficacy while engaging in critical reflection and action.
  • Critical Thinking & Problem Solving - Students consider a variety of innovative approaches to address and understand complex questions that are authentic and important to their communities.

Products

Students will conduct live demonstrations of their Alka-Seltzer rocket experiments in front of peers and teachers, showcasing their understanding of chemical reactions. They will create a presentation that includes a visual representation of their data, highlighting the effects of varying amounts of Alka-Seltzer and water on gas production. Each student will articulate their findings and answer audience questions, demonstrating their grasp of the scientific process and critical thinking.

Launch

Begin the lesson with an engaging demonstration of an Alka-Seltzer rocket launch to capture students' attention and spark curiosity about chemical reactions. Invite students to make initial observations and predictions about what they think causes the rocket to launch. Facilitate a brief discussion to connect their observations to the day's essential question, setting the stage for their own experiments.

Exhibition

Students will organize a live demonstration of their Alka-Seltzer rocket experiments for classmates and invited guests. During the exhibition, each group will explain their experimental design, highlight the chemical reactions observed, and answer audience questions to foster engagement and understanding. The event will conclude with a peer review session, where students provide feedback on each other's presentations, encouraging critical reflection and collaborative learning.
