Features 1、EFFECTIVE AND SAFE: This simple balance is designed for students with their learning needs and interests in mind, long lasting and efficient, ensuring that students have a safe and reliable measurement experience while exploring the joys of science 2、LONG LASTING MATERIAL: Made of excellent plastic, the balance can be used for a long time and is not easily damaged in the classroom or home environment. So students can play and learn without worrying about the durability of the equipment 3、WITH SCALE, EASY COMPARISON: The scale has a clear scale, so students can easily compare the mass of different objects. Not only help to develop students measurement skills, but also enable them to understand the concept of quality more intuitively 4、EXPLORE VOLUME: The clear plastic scale allow students to observe and compare the volume of solids and liquids. This design stimulate students curiosity about volume and measurement, allowing them to develop observation and estimation skills in their exploration 5、YEARS OF PRACTICAL MEASUREMENT FUN: This simple scale is not only suitable for use in the classroom, but also as a teaching aid in the family playroom. Durability and efficiency ensure that students can enjoy years of practical measurement and constantly improve their scientific knowledge and skills Specification Item Type: Balance Scale Toy Material: Plastic Use: Ideal for exploring basic measurement concepts and activities, for practical learning in the classroom or at home Performance And Construction: The simple balance consist of a base, a beam, 2 tray cylinders(200ml plastic beakers), a sliding weight, 8 x 10g calibration weights, and 4 x 5g calibration weights. The main components of the simple balance are made of engineering plastic. The beam is marked with reading scale lines and equipped with a sliding weight for reading weight measurements. The minimum reading accuracy of each grid scale line is 1g. The tray cylinder is a 200ml plastic beaker, which can be used to measure solid substances of general geometric shapes and liquid flow fluids The calibration weights are made of metal, with (10g x 8) + (5g x 4) = 100g configuration Package List 1 x Beam 1 x Base 2 x 200ml Graduated Cylinder 1 x Slider 8 x 10g Weight 4 x 5g Weight
