Apple Experiment - Will it Float? Students learn about the difference between "floating" and "sinking". Students take turns putting things in water and watching if the object sinks or floats. They will learn about the different types of things that float, and sink. Students are then shown an apple, and need to predict if the apple is going to float or sink using the iTalk2. What you do:      • Record the name of each float/sink object on the Step-by-Step         communicator, one object name per step.      • Create a "float"and a "sink" picture/symbol, each approximately         two inches in diameter. Put the symbols on either side of the iTalk2,         and record the words "float" "sink" on the respective sides. Create         a large "float" and "sink" picture/symbol. Glue each on a separate         sheet of construction paper.      • Students take turns using the Step-by-Step to read off the names of         each of the objects. As each object is named, students identify that         object from the set of objects on display.      • Put one object that floats in the water and show students the "float"         picture/symbol and explain that when something stays on the top of         the water, we say that it floats. Put one object that sinks in the         water and show students the "sink" picture/symbol and explain         that when something goes right to the bottom of the container of         the water, we say that it sinks. Instruct students that they are going         to take turns putting different objects in the water, to find out if the         object floats or sinks. Let students take turns selecting objects and         placing them in the water. Once they determine if the objects floats         or sinks place it near the "float" or "sink" paper.      • Review the types of things that float, and the types of things that         sink, and name reasons why something may float or sink.      • Show students the apple and ask them to think about whether an         apple will float or sink. Have them take turns using the iTalk2 to         predict if they think the apple will float or sink. A student or teacher         puts the apple in the water, and students say if it floats or sinks.         Students say if they made the right prediction.
