SC.912.P.8.7

This activity allows students to practice balancing chemical equations. It has three difficulty levels, and the students can practice with 5, 10, or 15 questions.

Type: Formative Assessment

In this activity students will model ionic and covalent bonds. Students will use colored fruit loops to represent electrons of various atoms.

Type: Lesson Plan

In this physically engaging activity students will debate with their peers whether a randomly drawn statement/diagram/compound name or formula applies to ionic bonds, covalent bonds or both types of bonds. Then sort themselves throughout the room accordingly. Peer support and collaboration are encouraged while the teacher facilitates proper placement. Activity concludes with a T chart graphic organizer and a writing assignment where students personify the bond types.

Type: Lesson Plan

Students will apply the mole concept and the law of conservation of mass to determine the empirical formula of a hydrate. Students will also use data from their experiment to understand the concept of mole ratios, formulas and predicting products from reactions. Students will interpret formula representation of compounds and understand their percent composition.

Type: Lesson Plan

Students will use this kinesthetic activity to further their knowledge regarding balancing chemical equations.

Type: Lesson Plan

This resource describes activity that will allow students to observe the effects of a chemical change as opposed to a physical change. It also gives them the opportunity to observe conservation of matter by modeling chemical equations. The main learning objective is the recognition that all chemical reactions create new molecules and that in a chemical reaction the original atoms get rearranged, bonding together in different ways.

This informational text resource is intended to support reading in the content area. From pimples to bad breath to passing gas, this article clears up the science behind some of the gross things our bodies do—acne, bad breath, and flatulence—in an attempt to make the gross seem a little less so.

Type: Text Resource

This informational text is intended to support reading in the content area. This article describes how scientists were able to reveal the spatial structure of left-handed and right-handed chiral molecules in gaseous solutions by using a combination of mass spectrometry and the Coulomb explosion.

Type: Text Resource

This informational text is intended to support reading in the content area. Scientists use normal table salt and expose it to extreme conditions to create new compounds that defy the classical rules of chemistry. These new compounds may help to produce better products with new applications and understand planetary cores.

• Differentiate between electron pair and molecular geometry
• Learn how to name electron pair and molecular geometries for molecules with up to six electron groups around the central atom
• Illustrate how electron pair repulsion affects bond angles

Type: Video/Audio/Animation

I use this simulation as an introduction to molecules and compounds to help students understand that atoms are not randomly joined to form a compound/molecule, but join in very specific patterns. In order to successfully complete the simulation activity, students must re-arrange molecules various ways. (In CH3COOH, both oxygens are bonded to the carbon atom, for example)

Type: Virtual Manipulative

This activity will allow you to practice balancing a chemical equation. You will have to make sure you are following the law of conservation of mass and recognize what can change to balance an equation.
You can:

• Balance a chemical equation.
• Recognize that the number of atoms of each element is conserved in a chemical reaction.
• Describe the difference between coefficients and subscripts in a chemical equation.
• Translate from symbolic to molecular representation.

Understanding molecular polarity by changing the electron-negativity of atoms in a molecule to see how it affects polarity. See how the molecule behaves in an electric field. Change the bond angle to see how shape affects polarity. See how it works for real molecules in 3D.

Some learning goals:
•predict bond polarity using electron-negativity values
•indicate polarity with a polar arrow or partial charges
•rank bonds in order of polarity
•predict molecular polarity using bond polarity and molecular shape
