Lab Activity: Demonstrate and Elaborate upon Mutational Types

Posted on April 10, 2013 by Mr. Saleh

Students will work in groups of three to demonstrate their understanding of various types of mutations that include chromosomal and gene mutations. Students will utilize colored paper clips to show examples of chromosomal mutations such as deletion, inversion, translocation, and nondisjunction, as well as point mutations that include substitution, deletion, and insertion. In each point mutation example, students will explain the outcome of such a mutation.

Section 12.1: Chromosomes and Inheritance

Posted on April 9, 2013 by Mr. Saleh

We will complete our discussion on chromosomes and inheritance in terms of sex-linkage and chromosome mapping as well as chromosomal mutations and gene mutations. In the remaining time, we will reinforce our discussed topic further.

Chapter 12: Inheritance Patterns and Human Genetics

Posted on April 8, 2013 by Mr. Saleh

As a precursor to learning the subject matter on Inheritance Patterns and Human Genetics, students are to create a word wall that is based upon the several concepts and ideas that are presented in the chapter.

Section 11.1: Defining Stoichiometry

Posted on April 8, 2013 by Mr. Saleh

Students will learn that the amount of each reactant present at the start of a chemical reaction determines how much product can form. This is the main principle of stoichiometry, measuring components to reflect the quantative relationship between reactant amount used and amount of the product produced through a chemical equation.

First, we will focus on mole ratios prior to learning molar conversions through chemical equations.

Lab Activity: Determining the Empirical Formula

Posted on March 27, 2013 by Mr. Saleh

Students will work within their assigned group to determine the empirical formula by experimentation using a specified amount of a metal (magnesium) as it undergoes combustion. Students will collect the necessary data using a 12-cm ribbon of magnesium, a crucible with its cover, scale, a triangular metal, a clamp, and a Bunsen burner. The students will follow a specified procedure to calculate and figure out the empirical formula of magnesium oxide.
