This activity models the states of matter and students investigate those states with a balloon/straw rocket.

Students are introduced to the similarities and differences in the behaviors of elastic solids and viscous fluids. Several types of fluid behaviors are described Bingham plastic, Newtonian, shear thinning and shear thickening along with their respective shear stress vs. rate of shearing strain diagrams. In addition, fluid material properties such as viscosity are introduced, along with the methods that engineers use to determine those physical properties.

Using three-dimensional scaffolds, these materials address the following topics:  - Atoms, elements, and molecules.- Properties of matter and energy. - Reasoning across systems and scale- Conservation of matter- Combustion as a rearrangement reaction- Chemical bondsEach packet is broken into five parts - data dive, core ideas, investigations, asssessments, and life connections. Formative assessments and checkpoints are embedded throughout each packet. The final packet prepares students for a summative assessment, with a provided practice assessment.Implementation instructions are embedded for each component of each packet. PDFs are included as attachments (in case the file formats are altered by this system).
