Journal Entry:

How can you use what you learned in this lab in the real world?

Learning Intentions

• We will learn what properties various bond types have.

• We will learn how to use data from experiments to determine types of bond in unlabeled substances.

• We will learn how to ask questions about lab analysis and conclusion to finish your What's in the Bottle? Investigation.

• We will learn how other classmates demonstrated metallic solid structure and properties.

Closing Task:

You can analyze and make conclusions using data from experiments about types of bonds in unknown substances.

Content Standards being covered:

Students can predict the type of bonding present between two atoms in a binary compound based on position in the periodic table and the electronegativity of the elements. (LO 2.17)

Metallic solids are good conductors of heat and electricity, have a wide range of melting points, and are shiny, malleable ductile and readily alloyed. (EK 2.D.2)

Ionic Solids have high melting points, are brittle, and conduct electricity only when molten or in solution. (EK 2.D.1)

Molecular solids with low molecular weight usually have low melting points and are not expected to conduct electricity as solids, in solution or when molten.  (EK 2.4.4)

Students are able to design or evaluate a plan to collect and/or interpret data needed to deduce the type of bonding in a sample of a solid. (LO 2.22)
