Highlights Fun STEM experiments will teach kids about engineering, physics and more3 Wooden Model Weapons to test: Catapult, Ballista and CannonFun Targets, Hoops and Buckets let kids test their aim and trajectoryTest for Accuracy, Distance and PowerIncludes a Starter Guide with Log Sheets to write results and discoveriesSTEAM and STEM kits teach kids important knowledge and skills Product Details With the ArtSkills Epic Lab Ballistic Battlers Science STEM Physics and Mechanics Kit, kids will learn to assemble and test 3 working model siege weapons This science kit is packed with options for educational fun. Kids can build a wooden Catapult, Ballista and Cannon, and then launch projectiles to hit targets. Fun science experiments are included to demonstrate machine engineering, potential energy and projectile physics Learn with STEM Building KitsSTEM stands for Science, Technology, Engineering and Math. Activity kits combining these fields are great for young, curious minds. Kids will learn to experiment, use logic, solve problems, think creatively, test their knowledge and complete hands-on projects. This is great enrichment for children, who can take these STEM skills with them into their education and their future Build Working Model MachinesThis fun science project activity lets kids assemble 3 working wooden medieval weapons. Clay is included for making projectiles, and the elastic bands create tension that allows the Catapult, Ballista and Cannon to really launch Kids can then use their models for the rest of the experiments Launch and LearnThis DIY STEM Science Kit will teach kids of all ages 6 and up about the physics and mechanics behind catapults, ballistae and cannons. Experiments are included to test for accuracy, distance, power and more. This Epic Lab Science Kit even includes Pop-Out Targets, Hoops and Buckets for practicing aiming and launching.When the experiments are complete, it's easy to keep playing and learning. Children can come up with their own experiments, compete with siblings and friends, or just play with the models What's Included?This Epic Lab Science STEM Kit for Kids includes:4 Pop-Out Wooden Model Sheets7 Rubber Bands4 Pop-Out Target Sheets3 Sticker Sheets3 Air-Dry Clay Packets3 Wood Dowels2 Pop-Out Bucket Targets2 Metal ScrewsScrewdriverMetal PinPaper Tape MeasureWood GlueSTEM Activity Booklet and Instructions Specifications STEM instructions and tips includedRecommended for children ages 6 and upConforms to ASTM D-4236 Health and Safety Standards UPC: 072125075409 Weight: 1.25 lbs RKU: SAM990004712
