"PARKWAY PLASTICS, INC."

Snap Circuits Motion contains over 50 parts and over 165 projects to complete, all motion and physics focused.

Build your own hands-on investigations around these assortments of real feathers, fur, and fish scales. Help students discover the unique features of feathers, see how fur keeps mammals warm, and why scales have remained a fish favorite for millions of years.

This slide is coated with a special adhesive formula (also known as "Positively Charged"), which allows the specimen to adhere to the slide easily, saving time and money in laboratory procedures.

This belt-driven generator may be used with our Steam Engine (63030-00 ). Operating at approximately 1500 rpm, the generator will produce enough electricity to light the included 3.8 volt bulb. The unit is mounted on a metal base (7.6×11.4 cm) and has a V-grooved pulley for the drive belt.

Latex eye dropper bulb. 2 cc (1.2 oz.) capacity, 0.25" (6mm) bore size, 0.625" (18 mm) diameter, 1.75" (45 mm) length.

For teens and adults alike, the Deluxe Handheld Digital Microscope is a fun, educational tool. It’s well suited for hobbyists, quality control inspectors, medical professionals, and scientific researchers.

These set of extended reach screwdrivers (.093”, .125”. .141” phillips #00, phillips #0), is perfect for delicate microscope repair/adjustment. Blades are manufactured from hardened, high tensile strength, alloy steel, securely molded into the ergonomic, anti-static handle. Made in the U.S.A., and backed by a lifetime warranty.

This handy meter measures soil moisture at the root level to prevent over or underwatering. No batteries are needed, so there is nothing to replace or wear out. It includes an instruction booklet, watering guide, and special needs information for 15o plants that correspond to meter readings. Range: 0 (dry) to 10 (wet). Size: 4"L x 2 1/2"W x 1 1/2"H. Probe: 4 1/4"L.

Our newly re-designed variable micropipettes are sturdily designed with volumes ranging from 0.1 to 5000 µl.

These delightful young reader books use splendid cut-outs, eye pleasing illustrations and even an amusing song or two to guide students through the changing seasons, to teach them that weather can be observed and that weather can vary from day to day and from season to season, and that weather can affect what we do and what we wear.

Nine level conductivity meter shows the relative conductivity/resistance of liquids and solids. As the conductivity of the tested material increases, the number of glowing red LEDs will increase to a maximum of 8, which indicates a very good conductor. There will be zero glowing red LEDs if the material has a very low electrical conductivity (is a good insulator).

Investigate and experiment with 7 functioning Wheel & Axle and Inclined Plane models designed to demonstrate science and technology concepts.

Students can determine, through investigation, if the machine multiplies the force it applies to the resistance (load), if the machine changes the direction of the force they apply, and more.

Erlab’s CaptairFlow Clean Air Enclosures are designed to prevent cross-contamination for applications such as non-pathogenic cell cultures, in-vitro cultures, microbiology, homeopathic preparations, electronics, and optics where product protection is required. They feature a high efficiency filtration system that provides a particle-free workstation around the manipulation, bringing HEPA filtered clean air down to the work surface.
