Adult supervision is recommended for all projects.  \nAbout the challenges in this pack  \n\n| Frozen Bunting\u003Cbr>Science challenge\u003Cbr>When the temperature outside falls below zero,\u003Cbr>the roads can become slippery. With this challenge,\u003Cbr>you can understand why salt has such an important\u003Cbr>part to play during winter whilst creating gravity\u003Cbr>defying frozen bunting. |\n| --- |\n| Christmas Chromatography\u003Cbr>Science challenge\u003Cbr>It is a common Christmas tradition to decorate\u003Cbr>a Fir tree with colourful ornaments and tinsel.\u003Cbr>You can make your own decorations this year\u003Cbr>using chromatography. |\n| Chocolate Chimney\u003Cbr>Engineering challenge\u003Cbr>As Father Christmas makes his journey around\u003Cbr>the world, he often uses a chimney to deliver\u003Cbr>his gifts. Now you can make your own edible\u003Cbr>chimney through welding chocolate. |\n\nCircuit Christmas Card  \nEngineering challenge  \nMany people give cards around Christmas to express their good wishes. With this challenge, bring your cards to life using a simple electrical circuit that will give Rudolph his famous shining red nose or make a Christmas tree with a shining star.  \nPlease note that the activities contained in here are intended for children ages seven and above. Adult supervision is recommended for all projects.  \nSCIENCE CHALLENGE  \nFROZEN BUNTING  \nUse the effects of salt melting ice cubes to make your own frozen bunting.  \nInstructions for Frozen Bunting  \n1. Cut the cotton string to your desired length. The longer the string, the longer the bunting will be.  \n2. Fill the bowl with water and place the ice cubes in the water, allowing them to float. Then, sprinkle salt on top of one ice cube.  \n3. Lay string across one ice cube and hold for  \n30 seconds.  \n4. Gently lift the string out of the water and your ice cube will be attached. Repeat steps 2 and  \n3 to make the rest of your frozen bunting.  \nMaterials  \n\n| Medium-sized bowl |\n| --- |\n| Enough water to fill the bowl |\n| Three to five ice cubes |\n| One teaspoon of table salt |\n| Scissors |\n\nCotton string  \nHow does it work?  \nSodium chloride, also known as salt, lowers the freezing point of water, causing ice to melt even when the outside temperature is below water’s normal freezing point of 0 degrees Celsius . This is why we use salt on the roads when there’s snow and ice to make them less slippery.  \nSCIENCE CHALLENGE  \nCHRISTMAS  \nCHROMATOGRAPHY  \nMake colourful snowflakes by separating ink molecules.  \nInstructions for Christmas Chromatography  \n1. Draw circles in different colours on the coffee filter paper.  \n2. Place the filter paper over some scrap paper. Fill your straw with water and place a few drops around the middle of the filter paper. Watch the colours begin to disperse.  \n3. Wait for the coffee filter paper to dry. Once it’s dry, fold it in half four times until you get a thin triangle. Then, cut the shape as shown on your folded triangle.  \n4. Unfold the folded triangle to reveal your colourful snowflake. Tie a cotton string onto your snowflake and hang it up.  \nMaterials  \n\n| One white\u003Cbr>coffee filter paper |\n| --- |\n| Washable markers |\n| Scrap paper |\n| Straw and a cup of water |\n| Scissors |\n\nCotton string  \nHow does it work?  \nChromatography is a technique used to separate mixtures . Since ink molecules weigh different amounts, as the water moves through the coffee filter paper, it drags the lighter ink molecules with it, leaving the heavier ones behind. This causes the colour to spread apart.  \nENGINEERING CHALLENGE  \nCHOCOLATE  \nCHIMNEY  \nUse the process of welding to make a weight bearing chimney.  \nInstructions for Chocolate Chimney  \n1. Place your wax paper on a flat surface and line up the four chocolate bars. Make sure that each chocolate bar is the same size.  \n2. Take one chocolate bar and hold the lo","cbCaihhXP6Th8uXe","https://ap.wps.com/l/cbCaihhXP6Th8uXe","pdf",8252416,"English","# About the challenges in this pack\n## Frozen Bunting\n## Christmas Chromatography\n## Chocolate Chimney\n## Circuit Christmas Card","[{\"question\":\"What age range are these Christmas challenges intended for?\",\"answer\":\"The activities are intended for children ages seven and above.
