The Environmental Chemical Test kit is a chemical test kit for the determination of six parameters commonly monitored for environmental testing: acidity, alkalinity, carbon dioxide, hardness, dissolved oxygen, and pH. This kit is equipped with all the necessary reagents and equipment to perform over 100 tests for each parameter. pH is obtained with Hanna‘s pHep®, pH electronic tester.

With this activity, teachers just add water to a dry powder for an intriguing, instant illumination in a bag.

These red marine bivalves are fascinating to observe as they propel themselves forward by expelling jets of water.

Mounted on molded plastic base, the unit consists of a base into the top of which may be screwed one of a set of four vases of differing shapes. An aperture in the bottom has a thin rubber diaphragm across it, bearing upon the short arm of the lever pointer. A moveable index on the vertical rod enables the height of water in vases to be set at same level. The apparatus is mounted on moulded plastic base that measures 25 x 17.5cm. The experiment is performed by screwing in each vase, in turn, and filling with water to the same level. It will be seen that the given height of water will result in the same deflection of pointer whatever shape of the vase.
