Specifically designed to dramatically and vividly show the classroom a pollutant in water, this kit is designed to permit students the opportunity of determining the presence of animal waste by seeing a dramatic color change that occurs in a lactose broth, students can determine if E coli are present. Grades 7-12.
Learn concepts of air pollution and its harmful effects using one form of a common air pollutant, sulfur dioxide on experiments with plant life. This kit provides instruction, apparatus and materials to experiment with plant seedlings exposed to a sulfur dioxide atmosphere at a known concentration which produces an effect on plant life that can easily be observed within several days.
Observe the color and state of matter for 14 different substances. Test liquids for the presence of odor and observe the texture of solids. Test the acidity or alkalinity of liquids. Test the solubility of solids in alcohol and water. All materials included except: water, stirring rod, graduated cylinder, balance, hand lens (optional), safety glasses, test tubes or depression plate for solubility test.

Today's emphasis on the artificial and natural ingredients of the foods that we eat has placed new emphasis on the chemical composition of that food. Examine the chemical, nature of many familiar food products. Experiments in this module: Presence of sugars, starches, fats and proteins, fruit discoloration, chemical composition of milk, presence of iodine in salt, calcium propionate in bread and the qualitative test for vitamin C and sulfur dioxide.
Students will learn important fossil concepts while investigating large specimens carefully selected to illustrate ideas about their formation. The Fossil Collection comes in a sturdy storage box that contains twelve large (2" x 3") specimens nestled in an attractive and durable display tray. The Teacher's Guide, reproducible student activity "field notebook", and reference cards for each specimen will ensure the successful use of these products. Also included are four quality hand lenses and a color identification chart designed to provide clues and answers for the student user. Grades 6-12. Ages 11-18.
Build your own motorized vehicles and machines with a wireless remote control unit
Unique six button infrared remote control
Three motors can be combined to make complex vehicles and machines
Assemble up to 10 models
48-page illustrated color instruction book included
Kit comes with everything you need
Ages 8 and up
The unique six button infrared remote allows you to control three different motors simultaneously, moving each of them forward or in reverse, with easy-to-activate touch sensors. The three motors can be combined to make complex vehicles and machines in numerous configurations limited only by your imagination. Assemble ten models demonstrating different ways in which the motors can be used including a bulldozer, car, three-wheeler, crane, antique car, plow, folding car, formula one racer, three-blade dozer, and robotic arm. After you have built the models in the instructions, you can design your own remote control creations! The kit comes with three motors, remote control unit, battery holder, and building blocks. Collaborate with your fellow junior engineers to build fantastic and functional remote-control creations! The 48-page color instruction book gives illustrated step-by-step instructions for the models to help children learn through play and develop their mechanical understanding, creative thinking skills, and hand-eye coordination.
Capacity: 610 Grams Sensitivity: 0.1 Grams Calibrations: Front Beam - 10g x 0.1g, Center Beam - 500g x 100g, Rear Beam - 100g x 10g Adam's Triple Beam is today's best value for teaching mass measurement concepts from a brand scientists worldwide have trusted for over thirty years. It offers the functions and durability you need in a generous 2610g capacity plus an array of special classroom features that you will appreciate. With a larger overall body than other triple beam balances, it's the sturdiest choice for the classroom. Quality construction with strong metal housing and a stainless steel pan. Innovative built-in tripod legs allow you to do density demonstrations wherever you want (without the inconvenience of having to clamp onto a table.)
An easy way to observe and study a large frog without dissection. The Pro-Sect system displays partially dissected, 4"-5" bullfrogs. The bullfrogs are displayed in a transparent, safe-to-handle, liquid-filled, plastic tray that is moldered and sealed. Some of the internal organs such as the liver, heart, and veins and arteries have been injected with colored latex to identify their circulatory function. A comprehensive study guide provides information to assist the teacher and students. Individual internal organs are identified on a transparent overlay for study or testing purposes.

The Lawson Political Floor Globe combines an easy-to-read political world map with a traditional furniture-style floor stand. The 12" blue-ocean globe features raised relief, providing a tactile representation of major mountain ranges and other elevated terrain.
A full swing meridian allows the globe to be repositioned for convenient viewing from different angles. The globe is mounted on a single [pedestal-style] oak-toned pedestal and finished with a broad gold-toned metal base for stability and a classic appearance.
Standing approximately 36" high, the Taylor is equally suited to classrooms, libraries, offices, and home study areas.
Specifications: 12" diameter world globe; blue-ocean political map; raised-relief surface; full swing meridian; oak-toned single-pedestal stand; gold-toned metal base; approximately 36" overall height; Herff Jones model Lawson; part #5120-4004.
Please Note: This is unused older inventory manufactured more than 20 years ago. The globe's cartography reflects the geography and political boundaries of its time and should not be considered current. Some country names, borders, place names, and other geographic information may have changed.
