This learning activity is designed to be used in a large introductory chemistry course, as part of a larger module of learning activities that includes prior viewing of an interactive instructional video. Instructional videos are to be viewed before class meetings. During class time, students work in small groups and discuss the presented information and question prompts, and will build upon the concepts discussed in that video in order to develop a new, extended concept.Students should be tasked with working together to complete the prompts in each section of the activity by a set time limit. After each section is completed, the entire class can share their answers via a personal response system, and the instructor can review and explain the correct responses, using the accompanying slide deck, which translates the problems into multiple-choice prompts.Instructional resources include 1) interactive instructional videos (these can be embedded directly into the learning management system) 2) the learning activity (.docx and .pdf) 3) the learning objectives (.docx and .pdf) and 4) the slide deck (.pptx). - Chemical Bonding- Resonance - Intermolecular Forces- Collision Theory- Equilibrium- Nucleophiles and Electrophiles

The basic objective of Unified Engineering is to give a solid understanding of the fundamental disciplines of aerospace engineering, as well as their interrelationships and applications. These disciplines are Materials and Structures (M); Computers and Programming (C); Fluid Mechanics (F); Thermodynamics (T); Propulsion (P); and Signals and Systems (S). In choosing to teach these subjects in a unified manner, the instructors seek to explain the common intellectual threads in these disciplines, as well as their combined application to solve engineering Systems Problems (SP). Throughout the year, the instructors emphasize the connections among the disciplines.

These lecture videos were made during the pandemic when most classes went online. They cover most of Physics-1, and a few chapters of physics-2. Subject: Physics Level: Community CollegeMaterial Type: LectureAuthor: Khalid BukhariDate Added: 2/19/2024

This readings-based course analyzes the structure and operation of government systems in developing countries, with particular emphasis on regional and local governments. Major topics include: the role of decentralization in national economic reform programs, the potential impact of decentralized governments on local economic development, determination of optimal arrangements for sharing fiscal responsibilities among levels of government, evaluation of local revenue and expenditure decisions, and assessment of prospects and options for intergovernmental fiscal reform. Emphasis is on basic economic concerns, with consideration given to political, institutional, and cultural factors.

Students are introduced to the concept of viscoelasticity and some of the material behaviors of viscoelastic materials, including strain rate dependence, stress relaxation, creep, hysteresis and preconditioning. Viscoelastic material behavior is compared to elastic solids and viscous fluids. Students learn about materials that have viscoelastic behavior along with the importance of engineers understanding viscoelasticity. To best engage the students, conduct the first half of the associated Creepy Silly Putty activity before conducting this lesson.

Students learn how common pop culture references (Harry Potter books) can relate to chemistry. While making and demonstrating their own low-intensity sparklers (muggle-versions of magic wands), students learn and come to appreciate the chemistry involved (reaction rates, Gibb's free energy, process chemistry and metallurgy). The fun part is that all wands are personalized and depend on how well students conduct the lab. Students end the activity with a class duel a face-off between wands of two different chemical compositions. This lab serves as a fun, engaging review for stoichiometry, thermodynamics, redox and kinetics, as well as advanced placement course review.
