Get to zero by becoming neutral. In using this method, let chemistry bring together broader ideas from math, economics and wherever value(s) are expressed in the negative.
Nomenclature and Formulas
This is the third in a series of classroom activities using paper tools to teach organic nomenclature. This post covers the two common naming systems used for carboxylic acids and derivatives, and second for alcohols, thiols, ethers, amines, and ketones.
Organic nomenclature is usually taught as an introduction to organic chemistry. To help introduce students to organic nomenclature in a way that clearly summarizes the patterns that exist, a paper tool for naming hydrocarbons was developed.
This creative activity will help engage your students in chemistry nomenclature.
Writing formulas is one of those concepts in chemistry that requires much practice and repetition for students to gain confidence. This remote learning activity is a fun way for students to practice name and formula writing that will not be as boring as a worksheet full of practice questions.
Determining the empirical formulas of ionic compounds based on charge balance is often a challenge for beginning chemistry students. Many visual aides have been developed for this purpose, from repurposing commercial interlocking bricks to custom 3-D printed bricks. This article describes yet another option– upcycled can carriers.
It can be difficult to engage students in reviewing for semester exams by using worksheets or practicing problems on the whiteboard. If you are looking to change up your review plans, you might consider using a lab activity that provides opportunity to revisit many of the topics that need to be covered.
Nomenclature is a tough topic. I tell students that we are living in the land of symbols while we study nomenclature. It is important but it is difficult to get them excited. I started fishing for resources. The American Association for Chemistry Teachers (AACT) has been a great resource to help me try new things.
According to the app store description, Chemical Formula Challenge is "An educational game to improve your ability to form chemical formulas from chemical names. You can either play it yourself or challenge a friend". The app features different levels of play such as easy, normal, and hard regarding the difficulty of the ions. As an example, beryllium chloride is considered "easy" while lead II nitride is considered "hard". The app then gives the user several ions to choose from and the user must then select the correct number of ions needed to balance the formula correctly.
This activity is used as a reinforcement activity following my use of JCE Classroom Activity #113: An Interlocking Building Block Activity in Writing Formulas of Ionic Compounds. It could be used as a stand alone activity to support writing ionic formulas and names.
