Students, in groups, research the issues surrounding one of several controversies involving food and globalization. Then they debate their position and show a PowerPoint presentation at a mock summit meeting.

High school learners read and discuss an article about genetic ancestry and genetic ancestry testing. They complete a paper and pencil activity that mimics the function of a DNA microarray and consider the ethics of genetic testing in...

Is DNA still present after picking fruit or cooking vegetables? Biology scholars extract and collect DNA strands in an impactful lab. Working groups prepare their samples and compare their results to negative and positive standard...

Students are able to discuss and prepare a written summary of a scientific article about AIDS. They propose solutions to the opening activity of which drug is more effective in the fight against AIDS.

Students experience a "hands-on" activity to get visual evidence of the physical nature of DNA and the process of DNA purification. They explore one method of chromosomal DNA isolation and DNA extraction.

Students follow the steps of translation and identify the reactants and products of translation. They able to explain that proteins are made of amino acids which are coded for by RNA. Students are able to give examples of proteins--...

Students describe the cell cycle. They make a connection between DNA replication and cell division. Students describe the parts of the cell that participate in cell division and the steps of cell division.

Identify the different stages of mitosis and what occurs in each stage with a straightforward biology lesson plan. Young scientists identify the importance of the cell cycle control in maintaining homeostasis, and then match the...
