The Teacher's Table of the Elements is a must have for the chemistry classroom. Teach your students the elements using easy to remember characters with connections to the elements using fun associations. The kit includes a set of character cards of the most common elements used in chemistry teaching along with useful information on the back. Use the Focus Box to hone in on key characteristics of the elements. The set also includes a set of cards with the standard symbols for a more traditional view of the periodic table. The Teacher's Guide has suggested lessons and fun activities to make your table usable all year round! 50" X 60"

This unit features several improvements over the standard Brownlee. The open front spring clips make it much easier to remove the test tubes while the tubes remain submerged. The test tubes have been graduated for a clear measurement of the volume of gas generated. The black acrylic background aids in viewing the water level while supporting the test tubes. The binding posts have been repositioned for easy access and greater safety. The unit measures 140mm x 203mm x 38mm. Instructions included. Brownlee Electrolysis Apparatus

A hydrometer is an instrument used to measure the specific gravity or relative density of liquids. The ratio of the density of a particular liquid is measured by its relationship to the density of water. The hydrometer is designed to be placed into the liquid filled hydrometer jar. Heavy liquids: 1.0-2.0 in .01 divisions, overall length 11-3/4"; .02Ib

Watch these trees grow crystals before your very eyes! Be amazed as colorful crystal buds begin to appear in as little as 15 minutes and are complete within 3 hours. Your little scientist will wonder how this happens and the included instructions with study questions help guide you though the process. Don't end the fun with growing just one, as this kit includes 3 trees with ideas on various experiments to determine how different locations and elements effect the growing process. Truly a fun and beautiful learning experience!

Construct hydrocarbon molecules (alkenes, benzene, etc.), functional groups (alcohols, acids, etc.) and isomers all with the same kit! Twelve individual packets each contain models of carbon atoms, oxygen atoms, hydrogen atoms, chlorine atoms and covalent bonds. 52 pieces per pack
