Acid Rain in a Bag— Demonstration Kit
Perform a simulation of acid rain formation in a plastic bag. Chemicals react to form a visi- ble brown cloud of nitrogen dioxide, which, in turn, acidifies water present in the system. An acid–base indicator shows the speed and degree to which the pH is altered.

Air Pollution Investigation— Super Value Kit
Expand your students’ knowledge about the quality of the air they breathe! In this kit, students are introduced to common types of air pollution. Air quality tests are performed for particulate materials in air, smoke pollution, acidic gases in air and acid rain.Includesdetailedbackgroundsection, reproducible student handouts, complete Teacher Notes.
Air in a Bottle—
Demonstration Model
This amazing model will help your students visualize the gases that make up the air and clear up the misconception that there is more oxygen in the air than nitrogen. The 3-liter model contains one million different colored spheres. Each color represents a different gas found in the Earth’s atmo- sphere. As students examine the model, they are challenged to determine which color represents which gas.

Airborne Particulates—Student Laboratory Kit
How clean is the air you breathe? In this hands-on kit, students will explore air pollution and discover just what types and amounts of particulates are found in local air. Students will have the opportunity to place observational slides in locations they think may have high amounts of particulates. Detailed observations about the particulates collected will then be recorded and studied.Kitincludesadetailedteacher’sguideandenoughmaterialsformorethan140tests! AP6460 | $35.70
