Ziplock Chemistry
Students investigate various chemical reactions when creating mixtures in ziplock baggies. In this chemistry lesson, students will recognize various chemical reactions and cite evidence. Safety and assessment strategies are included in...
Curated OER
Crystallization
Eighth graders analyze physical change in mass. In this chemistry lesson, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be familiar with elements,...
Curated OER
The Heat is On!
Fifth graders investigate evidence for changes in matter that occur during a chemical reaction.

PHENOTYPIC AND GENOTYPIC CHANGES IN BACTERIA
Students use a rapid method to render the bacterium Escherichia coli "competent" in order to uptake plasmid DNA. They also have growth on the plain LB plates by the untransformed cells (which serve as controls). Students perform a cell...
Curated OER
Phenotypic and Genotypic Changes in Bacteria
Students investigate a rapid method to render the bacterium Escherichia coli "competent" to uptake plasmid DNA. They demonstrate the phenotypic changes associated with transformation. They perform a cell resuspension from the...
