This kit is great for all doubting Thomases in your elementary through high school classes. Fast, fascinating and easy. This kit includes: Two black-colored blocks with rim for holding melting ice cube in place. The "cooler" one is of aluminum, which is an excellent conductor of heat. The ?warmer" block is of plastic foam, which is a very poor conductor of heat.

• Cargille Immersion oils meet ISO standards for performance
• Available in 1/4 oz bottles
• Types A and B are used for most fluorescent microscopy applications, type NVH.
Cargille Immersion Oil is required for high magnification and to obtain sharp images with clear resolution. These Immersion oils meet ISO standards for quality. Type A (low viscosity) and Type B (high viscosity) are used for normal microscopy applications with viscosities from 150-1250 (centistokes). The greater the gap between cover glass and objective, or condenser and slide, the more desirable high viscosity becomes. Type B is recommended when there is a larger gap between your cover slip and the objective. For extremely large gaps, NVH is required.
Sturdy plastic impact car features a graduated spring scale and a slide that is displaced on impact against an obstacle. Includes activity guide.

These Impact Recovery Sign Posts are more durable than steel posts, and are designed to withstand bumper hits and return to original position, without damaging the sign or vehicle. The unit’s anti-twist reactive spring assembly rebounds the panel to its upright, forward facing position when struck. Overall height of unit is 60”. Posts and panels are constructed of flexible plastic that is resistant to UV light, ozone and hydrocarbons.
The 5’ high Stop sign is ideal for permanent use in parking lots, garages, or other areas not covered by statutory requirements. The sign is made of a 24”x 24” white plastic panel with silver flexible High Intensity sheeting with red ink.
Recommended Uses:
• For permanent use within parking lots and parking garages.
• For temporary use by police, by emergency crews and during special events where temporary traffic control is needed.

Recommended Uses: Ideal for delineating crosswalks to reduce the risk of injury, death, and property damage.
These In-Street Pedestrian Crosswalk Signs provide enhanced conspicuity at un-signalized intersections in order to alert motorists to local laws concerning yielding to or stopping for pedestrians in crosswalks. The effectiveness of these pedestrian safety signs have been repeatedly supported by independent studies to demonstrate distinct changes in motorist behavior and accident incidence following installation.
Take care to avoid creating a trip hazard when using any sign in a crosswalk. Ensure that sign bases are installed outside the crosswalk area.
Bases NOT included (Order separately as indicated below)

This robustly constructed inertia demonstrator works reliably every time and is a great improvement on traditional versions of this classic experiment. A steel ball rests on a thin metal card on top of a pillar, and a spring-loaded catch is mounted next to the pillar. When the catch is released, a piston strikes the edge of the metal card sharply. The card flies out from under the ball, which remains in place on top of the pillar due to its large inertial mass. The card is tethered to the aluminum base for easy recovery after the experiment.
