Gravity is the force that pulls objects downwards (towards the centre of the earth). It&#8217;s what causes the marble to roll downwards.<\/p>\n<p>The second is <strong>energy<\/strong> (and conservation of energy). The faster an object is moving, the more energy it possesses. When objects collide, energy can be transferred from one object to another, changing their motion. When a ball hits a zigzag in the marble run, the energy is transferred from the ball to the marble run wall, and then back into the ball, causing the ball to change direction.<\/p>\n<p>The third is <strong>force<\/strong> (and the relationship between energy and force). The faster and heavier an object, the more force it will have. Heavier balls will require a slower track (or stronger magnets), else the force of the ball will push the track out.<\/p>\n<p>The fourth is <strong>friction<\/strong>. Friction occurs when two objects rub against each other (slowing movement and creating heat in the process). The texture of the ball and\/or the track will affect the friction.<\/p>\n<\/div>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-4319\" src=\"https:\/\/gosciencekids.com\/wp-content\/uploads\/2017\/06\/Make-a-DIY-magnetic-marble-run-for-the-fridge-using-toilet-paper-rolls-and-washi-tape.jpg\" alt=\"Make a DIY magnetic marble run for the fridge using toilet paper rolls and washi tape!\" width=\"600\" height=\"900\" srcset=\"https:\/\/gosciencekids.com\/wp-content\/uploads\/2017\/06\/Make-a-DIY-magnetic-marble-run-for-the-fridge-using-toilet-paper-rolls-and-washi-tape.jpg 600w, https:\/\/gosciencekids.com\/wp-content\/uploads\/2017\/06\/Make-a-DIY-magnetic-marble-run-for-the-fridge-using-toilet-paper-rolls-and-washi-tape-200x300.jpg 200w, https:\/\/gosciencekids.com\/wp-content\/uploads\/2017\/06\/Make-a-DIY-magnetic-marble-run-for-the-fridge-using-toilet-paper-rolls-and-washi-tape-100x150.jpg 100w, https:\/\/gosciencekids.com\/wp-content\/uploads\/2017\/06\/Make-a-DIY-magnetic-marble-run-for-the-fridge-using-toilet-paper-rolls-and-washi-tape-250x375.jpg 250w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<div>\n<p>Science isn&#8217;t the only subject that can be introduced here.
