Students investigate various chemical reactions when creating mixtures in ziplock baggies. For this chemistry lesson, students will recognize various chemical reactions and cite evidence. Safety and assessment strategies are included in...

Eighth graders analyze physical change in mass. In this chemistry instructional activity, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be...

Fifth graders investigate evidence for changes in matter that occur during a chemical reaction.

Fifth graders watch a demonstration in which a balloon is inflated using the gas created by combining vinegar and baking soda. Then, in groups, they combine various assigned substances and watch and record the results.

In this aqueous equilbria worksheet, students write the solubility product expressions for the given salts. Kids determine what affects the solubility of salts. Students calculate the pH of a buffer solution. This worksheet has 14...

For this changes worksheet, pupils compare and contrast the characteristics of physical and chemical changes. Students practice balancing equations. This worksheet has 5 fill in the blank and 7 short answer questions.

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...

Learners 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...

In this stoichiometry worksheet, students solve several problems using the stoichiometric method. Students find the percent, theoretical, and actual yield for all problems presented.
