I need to collect 12 samples of elements that I can tape onto a poster boared for my science class that I could find easily in my house .If anyone could help me keep things in real simple terms .Please thank you .
Jewelry can take care of the Gold, silver, and platinumA penny has zinc w/ copper coating and nickel has copper and nickel Salt Sodium and chloride A thermometer has mercury inside of itWater has hydrogen and oxygen Chalk has calcium Aluminum foil or a baking pan has aluminum Computer chips and contact lenses have silicon in them The head of matches contain sulfur For some of the flimsy items, like water or salt, you could put ti in a small baggie and staple/tape it onto the poster board
