Aluminum and Copper – A Guided Inquiry Experiment by Flinn Scientific Canada

There’s a lot of pretty chemistry in the reaction of aluminum wire with copper(II) chloride! Burnished copper crystals grow on the wire surface, and the blue color of copper(II) ions slowly fades. What relationships govern the relative amounts of aluminum and copper in this reaction? Can you predict the amount of copper that will be produced and the amount of aluminum that will be used up?

World’s First Car! and Car Safety- Veritasium

Physics is something that is directly applicable to car safety. Cars go fast, but they also sometimes collide with obstacles, which brings them to a sudden stop, subjecting the car and occupants to very high accelerations, which can cause injury or death. So the major idea to improve car safety is to reduce these accelerations and there are a number of ways to do this: Continue reading
