Have you ever seen a video where it looked like a car's wheels were spinning backwards even though the car was driving forward? This is called the wagon wheel effect, named after old movies where it looked like wagon wheels were spinning backwards. Even though you cannot see the effect in person, it can show up in videos of spinning objects. Find out why in this project and make your own videos of the wagon wheel effect! Read more

Have you ever made ice cream? It can be a lot of fun, and you end up with a tasty frozen treat! There is actually a lot of interesting chemistry that goes on behind making ice cream. For example, think about how you start out with refrigerated (or room-temperature) ingredients and then need to cool them down to turn them turn into ice cream. How do the ingredients change during this process? How important do you think it is that they are cooled to a certain temperature? In this science… Read more

How easy or difficult is it to build a gingerbread house? It depends on what you want your house to look like. Design possibilities are almost endless! You could make a multi-story building, try different shapes and sizes, or add extra features such as a balcony or chimney. The more complex your design gets, the more difficult it is to make sure that your house stays upright and keeps its shape. In this activity, you will become an engineer and design and build a gingerbread house that must… Read more

Have you ever heard that plastic can be made out of milk? If this sounds like something made-up to you, you may be surprised to learn that from the early 1900s until about 1945, milk was commonly used to make many different plastic ornaments, including buttons, decorative buckles, beads and other jewelry, fountain pens, the backings for hand-held mirrors, and fancy comb and brush sets. Milk plastic (usually called casein plastic) was even used to make jewelry for Queen Mary of England! In… Read more

Have you ever cooked something outside, like for a BBQ or while camping? It can be a lot of fun to be outdoors and enjoy eating the fruits — or burgers — of your cooking labors. Did you know that you can directly use solar power to cook food? This can be done using a solar oven, which is a low-cost, ecologically-friendly technology that seems to have everything going for it. In this science activity, you will build your very own simple solar oven out of a pizza box to gather the… Read more

Have you ever seen a lava lamp? They were the height of 1960's "groovy" room decorations. A few minutes after turning it on, a lava lamp has blobs of colored liquid floating towards the top of the lamp and then drifting back down. Making an actual lava lamp that you plug in would require some effort and unusual supplies, but you can create a non-electric version in just a few minutes with the help of the fizzing power of Alka-Seltzer. In this activity you can find out how to make your own… Read more
