In this activity, students interact with 12 models to observe emergent phenomena as molecules assemble themselves. Investigate the factors that are important to self-assembly, including shape and polarity. Try to assemble a monolayer by "pushing" the molecules to the substrate (it's not easy!). Rotate complex molecules to view their structure. Finally, create your own nanostructures by selecting molecules, adding charges to them, and observing the results of self-assembly.

Patterns Physics is the initial course in the 3-year high school Patterns Science sequence. Patterns Physics focuses on three-dimensional (3D) learning through culturally responsive, phenomena-based storylines that intertwine the disciplinary core ideas of physics and earth science with the scientific and engineering practices and crosscutting concepts as described in the Next Generation Science Standards (NGSS).
The Patterns High School Science Sequence (https://hsscience4all.org/) is a three year course pathway and curriculum aligned to the Next Generation Science Standards (NGSS).
Each course utilizes: - Common instructional strategies - Real world phenomena - Design challenges to engage students and support their learning.

Semiconductors are the materials that make modern electronics work. Learn about the basic properties of intrinsic and extrinsic or 'doped' semiconductors with several visualizations. Turn a silicon crystal into an insulator or a conductor, create a depletion region between semiconductors, and explore probability waves of an electron in this interactive activity.

What happens when an excited atom emits a photon? What can we deduce about that atom based on the photons it can emit? A series of interactive models allows you to examine how the energy levels the electrons of an atom occupy affect the types of photons that can be emitted. Use a digital spectrometer to record which wavelengths certain atoms will emit, and then use this knowledge to compare and identify types of atoms. Students will be abe to:
