It's the Slime Time

Students investigate the physical properties of a rather peculiar substance commonly known as slime. They devise and carryout a procedure for testing the effect of varying concentrations of either the poly(vinyl alcohol) or the borax...

Water is crucial to survival. Scholars gain an appreciation for water by reading about it, learning about its atomic properties, and investigating its properties through six stations in a lab activity.

Do you think chromatography paper suffers from separation anxiety? Young chemists make soap, slime, silly putty, and experiment with chromatography in this instructional activity. The material includes clear instructions for each...

Does a spider spin its web differently in space? What other ways might microgravity affect an arachnid? Pick a topic to research, plan an investigation, and follow astronauts on the International Space Station as they perform some of the...

Students choose a question from a given list and develop an investigation about it. In this biology lesson, students analyze bacterial growth by carrying out a guided experiment. They present their findings in class.

All plastics contain polymers, but not all polymers are plastic. Young chemists make their own polymer and compare the properties to those of other states of matter. After a reading passage, pupils answer analysis questions about natural...

Polymers make up nearly everything in the world around us; some are naturally occurring, while others are synthetic. Learn about how polymers form, what they are used for, and some of the potential environmental and health dangers of...

A PowerPoint presents features of polymers and two of its categories (thermoplastics and thermosets). Instructors conduct demonstrations to illustrate the Weissenberg Effect and the Barus & Kaye Effects of polymers in the first of...

Students are taken on a simulated "voyage" backward in time, to the beginning of our planet. They "witness" that beginning, the origin of life, and a number of key events from then to the present.

Learners combine the skills and concepts that they have developed to ask a simple question which can be answered on a Petri plate. They ask questions and design experiments for verification through collaboration with their classmates.
