LaMotte® Dissolved Oxygen Water Test Kit (Winkler Method)
Precalibrated test tubes and labware give fast, accurate results on-site, in the classroom, or in the lab.
Analysis of Minerals and Soils Lab Activity
The Analysis of Minerals and Soils Lab Activity teaches students to utilize physical and chemical techniques to thoroughly investigate crime scene samples.
What Rock Is It? Study Kits
Test your student's geology skills with this educational and fun activity. Students receive a bag of unlabeled rock specimens, then must test for physical and chemical properties in order to identify each rock sample. The easy-to-follow flowchart aids students in their classification decisions.
Geologic Time DVD
Students will see why scientists have divided the time scale into Eras, Epochs, and Periods and discover how the time scale is used.
Understanding Science: Weather Systems Video
The Understanding Science series is designed to aid the instructor in explaining difficult scientific concepts in an easy to understand format.
Geometry of Crystal Structure
Expanding on concepts learned in the Introduction to Mineral Crystals (60158-00) lab, here students construct models of the six basic crystal shapes, then derive their own definitions of each form by making observations, taking measurements and recording their findings.
