You could introduce the idea of fair testing by giving each kid/group the same materials to work with. The fewer materials you have, the more challenging it is to create a marble maze that keeps the marble in motion for a long time. Want to make an epic marble maze? Why not (safely!) prop up a table to create an incline and build onto it? If speed= distance/ time, can you work out the speed at which your marble is travelling? Change the incline of your board and assess how this affects your score. Use a stopwatch to record your times and make small changes after each attempt to see if you can improve your score. We like to set kids the challenge of keeping the marble on their board and in motion for at least as many seconds as their age in years. Why not challenge kids to source their own materials? Lolly sticks are really handy to use but you can use any small items you have in your classroom/ around the house. You can create your own board using a normal tea tray or large hard-backed book. The kits contain a range of items including wooden boards, cotton reels to support the boards, lolly sticks, Lego blocks, keyboard keys, and blu-tack. What happens when they are dropped from the same height at the same time? Why do you think this might happen?Īt Science Oxford, we have our own marble maze kits which we put together and use in our clubs and lend out to local schools. Watch what happens when I drop two pieces of paper: one is in a ball and the other is not. Gravity isn’t the only force that acts on falling objects. But this may not always happen… can anyone think why?Ī. This means, if you were to drop something from a height of 9.8 metres, gravity alone would make it hit the ground in 1 second. Did you know that on Earth, gravity always has the same amount of force? The force is 9.8 metres per second. In fact, gravity is one of the reasons why the marble stays on your board (rather than flying off into the air!) Gravity always wants to pull things directly down, but with the board tilted, friction causes the ball to roll slowly down the board before falling to the floor.ģ. What would happen if you tip your board up or down slightly?Ī) There’s a force called gravity that makes the marble move downwards.
When you place your marble on a horizontal board, it may roll around a little, but it won’t travel too far.ġ.
It means that things don’t move on their own! And when things are set into motion, they will keep moving until something makes it stop.Ī perfect way to demonstrate this is by making a marble maze.
Newton’s First Law of Motion states that an object will remain at rest or in uniform motion in a straight line unless acted on by an external, unbalanced force. Important vocabulary has been underlined the first time it is used. This Instructable uses scientific terminology which you may want to introduce to your students. We delivered our club as a 90 minute workshop, but you could integrate each of these activities into your syllabus in whichever way you choose. Our clubs inspire children to pursue science and are held in our brand new science centre in Oxford, England. This club was originally developed and delivered as a Saturday Science Club for children aged 5-9 and their accompanying adults. The best thing about this lesson? It's a totally fun and legitimate class to teach in the run up to Christmas! Why? Because Newton himself was born on Christmas day. It would be a brilliant precursor to the activities in this contest that create things that move, as kids will approach the tasks with an understanding of what they're trying to achieve and how science makes it possible. The activities in this Instructable are a great way of teaching kids how and why things move, through challenges that illustrate each of Sir Isaac Newton's Laws of Motion.
