In this experiment, students are if the law of conservation of mass holds true for both physical and chemical changes. Students observe two color-changing reactions, one physical and one chemical, and use scales to determine if the mass changes throughout the reaction.

MS-PS-1-5: Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
In this design challenge, students will work together to design a tool or process that successfully removes an invasive species from an ecosystem while minimizing harm to the native species and environment.
In this challenge, students will practice problem-solving and collaboration skills as they design, build, and test their wind turbine
prototypes. Students will explore the role of renewable energy in powering communities, learn about energy transfer and mechanical systems, and gain insight into the importance of sustainable energy solutions.
In this activity, students will read the story "In a Garden" by Tim McCanna. They will learn about the life cycle of a plant, what seeds need to grow, and what keeps seeds from growing. They will then create their own seed house and watch their seeds sprout!
