Students will get hours of enjoyment building different pipe systems on your modular STEAM wall and learn valuable skills while playing. This 80 piece set offers endless configurations, perfect for encouraging creative play and simple engineering. Build a tunnel system for the 5 included colored balls to race through and teach your students about teamwork when they work together to build the fastest track. This set is sure to be a hit with your students and offers a great opportunity to teach cause and effect and reasoning skills. Build several tracks and have students guess which one will send a ball through fastest and have them explain their reasoning to improve cognitive function. Pair with our hand pump system and tool set to add another level of excitement to this pipe building system. Arrange the pipes on a solid wall or around corners for a telephone system and teach students how sound travels. To clean, wipe with a damp cloth.
