Acid Rain in a Micro Environment—
Demonstration Kit
By: The Flinn Staff
Create a micro environment in an aquarium where sulfur and nitrogen oxides are generated. A simulated “rainstorm” carries the airborne pollutants to the “pond” and “countryside” below. The effects are immediate, obvious and unforgettable. Bring exciting visual imagery to otherwise vague, intangible concepts. Teacher Demonstration Notes are included.
Concepts: Environmental chemistry, acid–base indicators, pH, gases, neutralization reactions.
Time Required: 30 minutes
Materials Provided: Universal indicator, marble chips, sulfur, nitric acid, sodium hydroxide solution, hydrochloric acid solution.
Note: A 15- to 20-gallon aquarium, sand or fine gravel, large disposable roasting pan and aluminum foil are required and available separately; fume hood is strongly recommended.
Acid Rain Survey Kit
This kit contains everything you need to collect
and monitor the pH of rainwater or potentially
acidic freshwater sources. Each kit includes enough materials for an entire class—15 sample tubes with caps, 5 color comparison charts and enough test paper (pH 3.0–6.0) for over 75 determinations. Also included is a vial of Hydrion 0–12 pH test paper for testing and comparing the pH values of other liquids. All components are completely portable for use in the field.
Acid Rain Test Strips
Kit contains 15 strips of pH test paper and a color comparison chart— designed for measuring the pH of rain in the range of 3.0 to 6.0. A student taking an acid rain survey can take readings on 15 samples.

Microscopes and Stereoscopes
Flinn Scientific developed this line of microscopes to give you all the most popular features at every price point. What used to be superior is now standard with Flinn microscopes and stereoscopes!
• All Flinn microscopes have achromatic eyepieces and objective lenses and condensers to increase resolution.
• 40X and 100X objectives all retract to prevent damage to the slide or objective.
• LED illumination is standard and most of the scopes are rechargeable.
• A digital option is available for both the Economy and Advanced lines.
Equip your students with high-quality Flinn microscopes and stereoscopes!
