Excess Volume: Investigate the "Shrinking Liquids" Effect

Science Fair Project Idea

Scientific Method

Cooking, washing, and many industrial processes involve the mixing of liquids. How liquids behave when they are mixed is dependent on many factors. Sometimes, the mixing behavior of liquids can be quite surprising! For example, when you mix 50 mL of one liquid with 50 mL of another liquid, you might not end up with a 100 mL mixture! In this science project, you will explore this phenomenon, which we call the "excess volume" of mixtures. How do you think your mixing volumes will… Read more

You pick up litter, you reduce, reuse and recycle but did you ever consider conserving the soil? It might seem farfetched, but it turns out that soil erosion—or the wearing away of soil by water, wind and other natural forces—is a problem. Productive farmlands can disappear as nutrient-rich topsoil in fields washes away when heavy rains hit them. Waterways can get polluted as pesticides and fertilizers wash into them. Even human life and property are jeopardized, as soil erosion… Read more

With Halloween just around the corner, bloody scenes are just a block away. Whether it is dripping vampire teeth, a bloody nose, or a leaky bandage, fake blood is sure to bring characters to life, so to speak. While chocolate syrup might make convincing fake blood on black-and-white photography, it is not passable for real-life encounters or color film. In this activity, science helps you engineer your latest product: good-looking (and tasty!) fake blood. Read more
