BEAVER SCOUTS STEM Pilots – Fall 2013 Magnets Attract! PLAN Scouters should prepare the material. The magnet game is best played outside or somewhere that kids can run around. DO Activity # 1: What do magnets attract? Beaver Scouts work in groups of two to three to figure out what objects are attracted by magnets and which ones are not. • Scouters give each group a box filled with different objects (pebbles, corks, paper clips, keys, erasers, coins, iron needles or screws, etc) and some magnets. • Scouters ask Beavers to categorize the objects in any way they what. They eventually will figure out that some objects are magnetic and some are not. • When all groups are done, discuss how they organized their items. Scouters will guide the discussion towards the objects’ interaction with magnets and how they attract objects made of iron. • Discuss how magnets are used in daily life. Scouters guide Beavers through obvious uses of magnets (toys, refrigerator magnets, paperclip holders, some cabinet doors) to more invisible uses of magnets (credit and debit cards with magnetic stripes, computers, compass, motors, fans, cars). Activity # 2: How a compass works? • Beaver Scouts are divided into groups of two to three. Each Beaver has a magnet and must figure out how magnets interact with each other. They will soon find out that opposite colour poles attract each other and like colours repel each other. • Each group gets a compass and is asked to find out north. • Beavers put the compass on the floor and arrange their magnets around it in any shape they want. Which direction do the compasses point to now? Each compass will show a different direction because of the magnetic fields created by the magnets. • Beavers are asked to take away the magnets. Now what does the compass show? The compass will point to the north again. What happened? • After some discussion, Scouters explain that the compass is a magnet that shows the magnetic field of the earth and therefore points to the north. Activity #3: Magnet game • Each Beaver Scout is given a blue and a red piece of fabric (or rope). They should tie the fabrics on their wrists and each color will be a magnetic pole. • Beavers should hide their hands and gather in the middle. • On the count of three, Beavers will hold their arms up and move like a plane. They should form a magnetic chain by holding each others’ hands. But they should remember that like poles repel and unlike poles attract. • The game can be repeated several times to see if they are getting faster as a group. They can also decide what other shapes they want to create and try it out (square, circle, star, etc.). MAGNETS ATTRACT! REVIEW Here are some questions to ask once the activity is complete: • What did you learn about magnets today? What do you want to know more? • How can you use what you learned today in a camp or on a hike? • What elements of STEM were in this activity? Science? Technology? Engineering? Mathematics? • What did you like about these activities and games? What did you not like? • How would you do them differently? DescriptioN Walk on eggs, create structures with half egg shells and design and build a package that keeps the eggs safe!
