Easily expand your growing output!

A dramatic visualization of air pressure. This 1000 ml bottle has a balloon attached to its neck and an additional hole in its base fitted with a rubber stopper. You cannot inflate the balloon with the stopper in place, but remove the stopper and the balloon easily inflates. Replace the stopper, fill the bottle with water, remove stopper and Whoosh! – a geyser erupts!

Nymphoides aquatica. Dicot. The green tubercles that grow from this unique plant’s short roots store nutrients and look like bananas, giving the plant its common name. It is a floating plant that grows best in shallow water. It is easily reproduced from cuttings. Size: 4–6". Package of six.

Unless otherwise noted, plants are supplied in waterproof, plastic bags that keep plants fresh and healthy. Care instructions are included. Be sure to check with your state’s Department of Agriculture for any restrictions.

The Universal Specific Gravity Kit is designed to be used with any electronic scale with a minimum capacity of 15 grams and a tare (re-zeroing) function to easily measure the specific gravity of gemstones and minerals.
Just weigh the stone "in air" on the integrated weighing platform of the scale, then without changing the setup, weigh the stone in water by placing it in the underwater weighing pan of the gem holder suspended above the platform. Plug the two values into the specific gravity equation and obtain the specific gravity of your stone.

Includes: lightweight gem holder support and underwater weighing pan, independent, spill-resistant, adjustable beaker support, beaker for filling with water - 100ml capacity, aluminum test weight, stainless steel tweezers, instructions, reproducible Specific Gravity worksheet, table of 300 common minerals/gems sorted by SG, with 6 other properties, including refractive index.

Note: shown with Boreal Balance - not included.

Specially Prepared “Real-Life” Combinations
The world is teeming with a wide variety of microlife, making studying samples of pond water complicated especially for the beginning student. To lessen the confusion, WARD’S has prepared different culture mixes that reflect protist combinations that occur in the real world, yet eliminates the hundreds of other life-forms found in a collected sample. Comes with a dichotomous key and either the Working with Algae or the Working with Protozoa manual. Supplied in a single jar.

Contents: Ocean scum.

The LaMotte ColorQ meter is a simple way to test low and high concentrations of chlorine.
