Forget drinking your juice. Instead, try snacking on it! Use the steps and recipes in this food science project to transform drinks into semi-solid balls that pop in your mouth. The technique is called spherification and it is part of a larger food science trend called molecular gastronomy— but we just call it yummy science!

Do you think you could build a car powered by nothing but air? A balloon-powered car is pushed forward by air escaping from a balloon, and it is fun and easy to build with materials you already have around your house. Can you imagine how you would want your own balloon-powered car to look? Can you design a car that will travel as far as possible? You can even measure your car's speed using your smartphone and a special sensor app. Get ready to grab some simple supplies to bring your idea to…

Do you filter your tap water before drinking? Many commercials claim these filters make your drinking water cleaner and safer. But what, exactly, are these filters doing and is the water really cleaner afterwards? The cleaning power comes from their filling material, called activated carbon. It exists in all kind of forms: powder, granules, foams, and blocks. Do you think it matters what type of activated carbon is inside the filter? In this activity you will investigate whether larger or…

The makers of sports drinks spend tens to hundreds of millions of dollars advertising their products each year. Among the benefits often featured in these ads are the beverages' high level of electrolytes, which your body loses as you sweat. In this science project, you will compare the amount of electrolytes in a sports drink with those in orange juice to find out which has more electrolytes to replenish the ones you lose as you work out or play sports. When you are finished, you might even…

Have you ever looked at two girls and thought they looked so similar that they must be sisters? What about a father and his son — have you ever seen a boy who looked just like how his father did when he was younger? We can often tell that two people are related because they appear to have several similar physical traits. This is because children receive half of their DNA — their genetic blueprints — from each parent. What about fingerprints — are they an inherited trait?…

Try your hand at this engineering challenge. Can you build a "launcher" device to launch a ball as far as possible and a "receiver" to catch it? Building a receiver provides an extra twist to a traditional catapult project. Add to the challenge by using a limited set of materials to build your machine and calculate a score based on your throw distance and materials used.

Have you ever had a refreshing bath using a bath bomb? A bath bomb is several ingredients mixed and molded into a shape, which becomes fizzy when it touches the water. It can be quite a relaxing experience, especially if your bath bomb has a nice fragrance or includes some bath salts. The fizz is the result of a chemical reaction taking place between different ingredients within the bath bomb. In this science project, you will get to make your own homemade bath bombs and explore how changing…
