Introducing a realistic set of the most important traffic signs kids will learn. Incorporate these signs into obstacle courses or activity stations. Create mock drivers ed routes for scooter teams. Multi-Dome Traffic Signs are not just for physical education... use them throughout your building, at outdoor events or even at your bus and pick-up areas. Multi-Dome Traffic Signs stand 36" high and have large surface areas (up to 16" by 16") so they can be seen from long distances. Multi-Dome Traffic Signs are constructed from a durable, lightweight corrugated styrene plastic, so they're safe if they tip and won't damage floors. Set includes 6 slip-on poles (no assembly required.). Dome base not included. Be sure to visit our sister site Wolverine Sports to order more multi-dome accessories and scooters.

Hanging metric weights used to extend scale capacity of Ohaus 750-S0 and 750-SW metric triple-beam balances (not included). Cast iron construction has durability and long life. The set of three attachment weights includes two 1,000g weights and one 500g weight.
Calibration weights are used to measure the weight or mass of an object using a balance or scale, or to calibrate other weights or instruments. Calibration weights can be certified or uncertified. Certified weights meet strict guidelines for accuracy and can usually be recertified. Certified weights are used in labs where a high degree of accuracy and repeatability is required. Uncertified weights are used where a lower degree of accuracy is required, including student laboratories, rough weighting operations, and measuring force. Hooked and slotted weights are often used to measure pressure, torque, and tensile strength, and to demonstrate basic laws of physics. Calibration weights differ from lab weights, which are general purpose weights used to hold an object in place, similar to a paperweight.
