If you have ever tried to make bubbles using plain water, you may have seen that it does not work. This is because the surface tension of water is too high. When detergent is added to water, it lowers the surface tension so that bubbles can form. Other things can be added to this mixture, such as corn syrup or glycerin, to make a solution that is even better for creating bubbles. In this science activity, you will find out which solution creates the best bubbles! Read more

Have you ever had a sunburn? If so, you know how powerful the Sun's heat can be! Did you know that this heat can also be turned into electrical energy? You may have heard about solar cells, but what about a solar updraft tower? This very simple structure uses the sun to heat up air, which then powers a turbine within a large tower. In this activity, you will build one of these towers yourself. Do you think you can make a propeller spin with just hot air? Read more

If you could choose to be an animal, would you rather be a predator or prey? For prey animals, survival in the wild means a daily struggle to escape potential predators. Predators, on the other hand, have to work very hard to make a catch. Some prey animals have evolved clever strategies to protect or defend themselves against predators. One common strategy is camouflage. Camouflage allows animals to blend into their surroundings so predators can't see them. Will this strategy increase an… Read more

Do you remember your last parade, party, or fair? You might have been surrounded by sounds of all kinds: fireworks, music, and, maybe even the famous (or infamous) sound of kazoos. A kazoo is a very simple musical instrument, made up of a hollow pipe with a hole in it. They may be simple, but these little noisemakers are a great way to explore sound. In this activity you'll be investigating how kazoos work by building your own! Read more

Why is it important to eat healthy and exercise? If you don't, you might end up with a cardiovascular disease. These diseases are conditions that affect your heart and blood vessels. The job of your cardiovascular system is to transport blood through your heart, veins, and arteries, to provide oxygen and nutrients to your body. If this blood flow doesn't work properly anymore, it can have serious consequences. In this activity, you will find out what happens to the blood flow of people that… Read more

Have you ever heard someone say, "That plant is thirsty," or, "Give that plant a drink of water"? We know that all plants need water to survive, even bouquets of cut flowers and plants living in deserts. But have you ever thought about how the water moves within the plant? In this activity, you will put carnations in dyed water to figure out where the water goes. Where do you think the dyed water will travel, and what will this tell you about how the water moves in the cut flowers? Read more
