Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

Junior chemists manufacture biodiesel in the lab. In this exercise, they check the purity of the biodiesel using thin layer chromatography. They also calculate its density and heat of combustion. They are sure to rise to the...

Learners explore online tutorial on polymers. In this chemistry activity, they create two polymers in the lab and compare their properties. They write a sales letter about their new and improved polymer product.

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

Students read about Humane Genome Project, examine structure and function of DNA, and participate in gel-electrophoresis lab. They complete Internet activity to test their knowledge of DNA.

Students practice writing research proposals to test the color fastness of a dye once it has been exposed to a t-shirt. Each proposal needs details of experimental design, length of treatment, and means of cleaning the shirt. All...

Students investigate the carbon dioxide content of different sodas. In this chemistry instructional activity, students explain why PET containers are preferable than HDPE for soda bottles. They collect data and graph them.

Young scholars conduct a series of experiments to explore carbon dioxide properties. In this chemistry lesson, students explain the production and uses of this gas. They measure its amount in soda and waste product of yeast.

Ninth graders generate and analyze data to determine which and how much of two polymers best absorb oils, formulate procedure to accurately determine how many times its own weight particular polymer can absorb, and develop understanding...
