Earth Science Educational Materials

Comprehensive, economical kits enable multiple activities for learning about minerals and rocks and their various physical properties, as well as other essential properties of natural processes on planet Earth. Modern technology allows for accurate tracking and prediction models for aiding comprehension of immense natural phenomena such as hurricanes and earthquakes, and VWR offers a wide variety of kits to choose from for studying historical geological stages in the Earth’s development and the remnants of those stages such as fossils or ash from volcanic eruptions.

Experimentation kit, bioremediation by oil eating bacteria

Experimentation kit, bioremediation by oil eating bacteria

Supplier: EDVOTEK

Oil spills cause devastation to the environment, killing sea life, birds, and coastal plants. Spraying areas of contamination with oil-eating microbes accelerates the degradation of the oil. This process is known as bioremediation. In this open-ended experiment, students grow a mixture of oil-eating bacteria and observe their effectiveness at degrading a variety of oils.

Experimentation kits, water quality testing I: chromogenic analysis of water bacteria contaminants

Experimentation kits, water quality testing I: chromogenic analysis of water bacteria contaminants

Supplier: EDVOTEK

Safe drinking water is vitally important to health. Both pathogenic and harmless bacteria can be found in the guts of mammals and birds. Testing water for every possible type of pathogenic bacteria is slow and costly. Thus, water is tested for a characteristic type of gut bacteria - the coliforms - including the familiar E. coli. Presence of coliforms is an indicator for faecal contamination. In this experiment, students test for coliforms in simulated contaminated water using colour and fluorescent reagents. They can use these same reagents to test water samples from the environment. As an extension activity, a Gram Stain test can be performed on the collected samples.
