4 ) Plan and conduct an investigation to classify properties of matter as intensive (e.g., density, viscosity, specific heat, melting point, boiling point) or extensive (e.g., mass, volume, heat) and demonstrate how intensive properties can be used to identify a compound.

[SC2015] CHEM (9-12) 9 :

9 ) Analyze and interpret data (e.g., melting point, boiling point, solubility, phase-change diagrams) to compare the strength of intermolecular forces and how these forces affect physical properties and changes.

[LIT2010] WRI (9-10) 7 :

7 ) Conduct short as well as more sustained research projects to answer a question (including a self-generated question) or solve a problem; narrow or broaden the inquiry when appropriate; synthesize multiple sources on the subject, demonstrating understanding of the subject under investigation.

[LIT2010] WRI (9-10) 8 :

8 ) Gather relevant information from multiple authoritative print and digital sources, using advanced searches effectively; assess the usefulness of each source in answering the research question; integrate information into the text selectively to maintain the flow of ideas, avoiding plagiarism and following a standard format for citation.

[LIT2010] WRI (9-10) 9 :

9 ) Draw evidence from informational texts to support analysis, reflection, and research.

Students will be conducting a series of investigations in order to compare and contrast the various intermolecular forces that exist between compounds. First, students will rank 4 substances according to their melting points. Second, students will work together using the jigsaw research approach to understand the 4 types of intermolecular forces. And lastly, students will use the information gained to go back to their data collected and compare their original compounds and type of intermolecular bond they exhibit.

This lesson plan results from a collaboration between the Alabama State Department of Education and ASTA.

In this activity, students will watch a quick video clip from YouTube that will demonstrate how dry ice can quickly freeze fruit, discuss properties of dry ice, and show how it sublimates. After watching the clip, students will then conduct seven different mini-laboratories with dry ice to expand their knowledge of the properties of matter and explore the process of sublimation - a solid transitioning directly to a gas skipping the liquid phase.  

This activity was created as a result of the ALEX Resource Development Summit.

In this video, Hank introduces us to the world of organic chemistry and, more specifically, the power of hydrocarbon. He talks about the classifications of organic compounds, the structures & properties of alkanes, isomers, and naming an alkane by observing its structure.

Today Hank talks about the deliciousness of alkenes & alkynes, their structures, and how to remember which is which by simply knowing the alphabet. Also, he breaks down hydrogenation, halogenation, polymerization, and triglycerides all while helping us figure out the meaning of different names for fats.

In this video, Hank talks about aromatics and cyclic compounds and naming their substituents, resonance as well as common reactions & uses. What's that smell? Smell's like Organic Chemistry!

Liquids are everywhere, but at the same time, they possess some incredibly unique qualities when compared to the rest of the matter in the universe. In this episode of Crash Course Chemistry, Hank gives you information on things like London dispersion forces, hydrogen bonds, cohesion, adhesion, viscosity, capillary action, surface tension, and why liquids are just weird.
