Teaching the Chemical and Structural Properties of DNA

Two pages of neat notes introduce chemistry novices to chemical reactions. Opening with a simple description of what constitutes a chemical reaction and progressing to the practice of balancing reaction equations, this worksheet is...

Young chemists have unknown compounds they need to sort. Performing three different tests on each, the chemical behaviors they observe become the basis for data analysis. 

Newcomers to chemistry compare hydrogen peroxide to water, realizing that the difference of one oxygen atom significantly affects the chemical properties. Other pairs of compounds and their formulas are also examined. A few chemical...

Nine action-packed organic chemistry exercises are contained in this mini-unit on carbon containing compounds. Examples include constructing models of alkanes, producing aromatic esters, and preparing pigments for paint and dyes....

Some basic chemistry concepts are fundamental to understanding biology. Learners explore how molecular structure plays a role in biological processes, especially the structure of the water molecule. The final page focuses on water's...

A splendid chart of information about chemical bonding tops the first page. In it you will find information on London forces, permanent dipoles, hydrogen bonds, ionic bonds, and covalent bonds. A four-step process for assigning...

Bond with your chemistry learners through a presentation on chemical bonding. This attractive and informative collection of slides walks beginning chemists through types of molecular bonds, orbital shapes, how to draw Lewis structures,...

Introduce biology classes to the structure of DNA, the role of genes, and how mutations occur with this nifty resource. After viewing an animated video, discuss the accompanying Think questions and then explore the myriad of additional...

Young scholars are able to extract and observe a visible amount of DNA from Escherichia coli cells. They discuss the properties of DNA. Students confirm the presence of DNA by a reaction with an indicator.

Learners describe the structure of DNA and its components and can comprehend that real DNA and its cartoon representation are very different. They are able to link DNA to genetic make-up.
