Have you ever wondered why some things disappear when they are put in water but other things do not? For example, you may have seen that salt disappears, or dissolves, when it is mixed in a glass of water. But when you throw a rock in a stream it will not usually dissolve, and instead it will just sink to the bottom. And then there are some things that do not act like the salt or the rock. These are called colloids. If you have made Oobleck out of cornstarch and water, then you have seen…

If you love to hit the half pipe with your snowboard or skateboard, then you have tested the strength and durability of laminates. Laminates are sandwiches of different materials that are glued together in layers to give strength and flexibility to an object. In this experiment, you can test if laminating wood can make it stronger and able to support a heavier load. How much weight can it take before it breaks?
