Reflection: Staircase of Complexity Bonds: The Basis For Biology - Section 3: Direct Instruction - Bonds: The Building Blocks Of Life


Although the NGSS do not state that types of chemical bonds must be covered in the high school life science curriculum, it is imperative for students to understand how molecules/atoms form chemical bonds to master standard HS-LS-1-6: Construct and revise an explanation based on evidence for how carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form amino acids and/or other large carbon-based molecules.  

In my opinion, the only way that students can visualize the abstract combination of carbon, hydrogen, and oxygen is to have a prior knowledge of the different types of chemical bonds and be able to explain how the interaction of the electrons allow for these chemical reactions to occur.  This lesson will introduce your students to the types of bonds that are most common in biochemistry so when you reference these bonds in future curriculum your students will have a point of reference to understand your lesson!

Bonds: The Basis For Biology

Unit 4: How It All Happens: An Introduction To Biochemistry
Lesson 4 of 11

Objective: SWBAT determine if a chemical reaction will result in an ionic or covalent bond based on the location of the elements on the periodic table.

Big Idea: No more guessing! Students will utilize the periodic table and their understanding of atoms to predict the types of bonds that will form during simple chemical reactions.
